[0203] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the relevant applications and are not intended to limit the scope of this disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the relevant applications are shown in the accompanying drawings.

[0204] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing embodiments of this disclosure only and is not intended to be limiting of this disclosure.

[0205] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0206] It should be noted that the terms "first, second, third" used in the embodiments of this disclosure are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0207] Before introducing the embodiments of this disclosure, we first define three directions that may be used in the plane to describe the three-dimensional structure in the following embodiments. Taking the Cartesian coordinate system as an example, the three directions may include a first direction, a second direction, and a third direction.

[0208] Please see Figure 1 A semiconductor chip (specifically, a memory chip or a logic chip) may include a top surface on the front side and a bottom surface on the back side opposite to the front side. Ignoring the flatness of the top and bottom surfaces, the direction intersecting (e.g., perpendicular) with the top and bottom surfaces of the semiconductor chip is defined as a third direction. On the top surface of the semiconductor chip, two mutually perpendicular directions are defined, namely a first direction and a second direction, where the first direction is perpendicular to one edge of the semiconductor chip, and the second direction is perpendicular to the other edge of the semiconductor chip.

[0209] Please see Figure 1 A semiconductor chip includes a substrate, one side of which is used to fabricate devices (such as transistors, capacitors, etc.) forms an active surface. Multiple metal layers, such as M1, M2, M3, etc., are distributed between the substrate and its top surface. Figure 1 The diagram also shows two types of conductive vias (e.g., silicon conductive vias), both used to enable signal connections between different stacked chips.

[0210] like Figure 1 As shown, for a type 1 conductive via, it penetrates the bottom surface and the top surface in a third direction, and the conductive via is connected to the internal circuitry of the chip through a metal layer.

[0211] like Figure 1 As shown, for type 2 conductive vias that penetrate the substrate only along a third direction, signal transmission is achieved in conjunction with a contact structure that penetrates the top surface along the third direction. The contact structure and the conductive via are not directly electrically connected, but rather indirectly connected through a metal layer. For example: Figure 1 The contact structure is connected to M4, and M4 is connected to M1 via M3 and M2 in sequence. M1 is then connected to the conductive via. Of course, in other embodiments, the contact structure and the conductive via can also be designed to be directly electrically connected.

[0212] Furthermore, the types of conductive vias are not limited to the two types mentioned above; the examples are merely illustrative. In particular, the illustrations presented in this disclosure are not intended to be actual views of any particular microelectronic device or its components, but are merely idealized representations used to describe illustrative embodiments. Therefore, the drawings are not necessarily to scale.

[0213] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0214] In one embodiment, a memory chip and a logic chip are provided. Both the memory chip and the logic chip include multiple conductive vias extending through the chip in a third direction. These conductive vias are used to enable signal transmission between different chips, and all conductive vias can be located at any position. Specifically, every four conductive vias can be functionally considered as a group of conductive vias, but the individual positions of these four conductive vias are not limited.

[0215] In one specific embodiment, eight of the aforementioned memory chips and one logic chip are stacked to form a 3D memory device. Simultaneously, the conductive vias of the eight memory chips are aligned along a third direction, and the nine aligned conductive vias along the third direction are connected to form an electrical path. See also... Figure 2A This illustrates a signal transmission diagram of a chip stacking structure. (Example) Figure 2A As shown, the chip stacking structure includes memory chips 0-7 and logic chips. Figure 2A For each memory chip, only 4 conductive vias D0 to D3 are shown, and these 4 conductive vias D0 to D3 belong to the same conductive via group. At this time, the conductive vias D0 in 8 memory chips and 1 logic chip are aligned to form a single electrical path, and the conductive vias D1 in 8 memory chips and 1 logic chip are aligned to form a single electrical path... The remaining conductive vias are similar.

[0216] At the same time, each memory chip and logic chip is also equipped with multiple driver circuits. Figure 2A Only one driving circuit is shown in the image (the rest are not shown), and each conductive via is connected to one driving circuit; each memory chip also has multiple data selectors (e.g., Figure 2A In the configuration (mux0~7), each via group corresponds to one data selector. That is, all the vias in a via group are connected to the data port of the data selector through their respective drive circuits. In other words, the data selector can choose which via transmits the signal to the memory chip or which via outputs the signal from the memory chip.

[0217] For the overall storage device, different regions in different memory chips are managed by different channels (e.g., CH0, CH1, CH4, CH5). The signal Signal_CH0 of channel CH0 is transmitted through an electrical path consisting of "conductive via D0 in the logic chip, conductive via D0 in memory chip 0, conductive via D0 in memory chip 1, conductive via D0 in memory chip 2, conductive via D0 in memory chip 3, conductive via D0 in memory chip 4, conductive via D0 in memory chip 5, conductive via D0 in memory chip 6, and conductive via D0 in memory chip 7". The selection signals of the data selector mux0 in memory chip 0 and the data selector mux4 in memory chip 4 are both SEL_C0, that is, the signal Signal_CH0 can enter memory chip 0 and memory chip 4 through the aforementioned electrical path; the signal output process can be understood similarly.

[0218] As can be seen from the above, memory chip 0 only needs to obtain signals from conductive via D0, memory chip 1 only needs to obtain signals from conductive via D1, and so on. That is, each memory chip only needs to obtain signals from one of the conductive vias in a group of conductive vias. It is worth noting that different memory chips may need to obtain signals from different conductive vias. However, since all memory chips need to be designed with the exact same structure during manufacturing (to maximize cost and labor savings), all conductive vias in the memory chip need to be designed with corresponding drive structures and data selectors to achieve structural consistency. Furthermore, when using… Figure 2A In the chip stacking structure shown, each conductive via corresponds to a driving circuit. During the operation of this chip stacking structure, it is necessary to drive all the driving circuits of all memory chips in the same channel. This results in a large load and large parasitic capacitance, which seriously affects the performance of the chips, restricts the transmission efficiency, increases power consumption, and also limits the number of chips stacked in the three-dimensional device.

[0219] In another embodiment, please refer to Figure 2B This illustrates signal transmission in another chip stacking structure. Specifically, Figure 2B Only some conductive vias (D0~D3) are marked; others are omitted. However, for... Figure 4 For example, the markings for conductive vias aligned along a third direction are the same. Figure 2BAs shown, the chip stack structure also includes eight memory chips and one logic chip aligned along a third direction. However, the conductive vias in each memory chip are rotatably connected to another conductive via at a different position in another memory chip, achieving a spiral upward connection as a whole. That is, the signal Signal_CH0 of channel CH0 is transmitted through “conductive via D0 in logic chip 0 – conductive via D1 in memory chip 0 – conductive via D2 in memory chip 1 – conductive via D3 in memory chip 2 – conductive via D0 in memory chip 3 – conductive via D1 in memory chip 4 – conductive via D2 in memory chip 5 – conductive via D3 in memory chip 6 – conductive via D0 in memory chip 7”, and the other signals are similar.

[0220] In this way, memory chip 0 can obtain the signal Signal_CH0 through the output terminal of the conductive via D0 in the logic chip, memory chip 1 can obtain the signal Signal_CH1 through the input terminal of the conductive via D0 in memory chip 0, memory chip 2 can obtain the signal Signal_CH4 through the input terminal of the conductive via D0 in memory chip 1, memory chip 3 can obtain the signal Signal_CH5 through the input terminal of the conductive via D0 in memory chip 2, and so on. For each memory chip, only one conductive via is needed to connect to the driving circuit in each group of conductive vias, and no data selector is required, which reduces the number of devices and thus reduces parasitic capacitance. However, compared to Figure 2A The conductive via direct connection configuration. Figure 2B The process of rotary connection of through-holes in medium-voltage systems is more complex, specifically... Figure 2B A horizontal interconnect structure needs to be set between adjacent conductive vias in each memory chip. Figure 2B (Only one is marked with a pentagram in the image). The signal interconnect structure can be a metal interconnect, a conductive via, etc. To achieve the rotating connection of the conductive via, the input signal signal_CH0 must first be transmitted upwards from the conductive via D0 of the logic chip to the interconnect structure below the conductive via D0 of the memory chip 0 (not directly connected to the conductive via D0 of the memory chip 0), and then horizontally transmitted from the interconnect structure below the conductive via D0 of the memory chip 0 to the conductive via D1 of the memory chip 0. That is: Figure 2B The structure shown requires the signal to pass through the interconnect structure in each memory chip during the signal transmission process, and the output signal is similar. This inevitably leads to an increase in parasitic resistance and also increases the complexity of the manufacturing process.

[0221] In particular, Figure 2A and Figure 2BIn the chip stacking structure, all chips are active-facing, meaning that different memory chips are stacked back-to-back, and memory chips and logic chips are also stacked back-to-back, that is, the bottom surface of the upper chip is in contact with the top surface of the lower chip.

[0222] In summary, on the one hand, Figure 2A The chip stacking structure requires numerous conductive vias to transmit the corresponding signals. Combined with the associated driver circuitry and data selectors, this results in a large load and parasitic capacitance. Figure 2B The chip stacking structure has a large parasitic resistance due to its rotational configuration; on the other hand... Figure 2A and Figure 2B All existing stacking structures have certain problems and cannot be directly applied to face-to-face stacking structures. Specifically, if we want to further realize face-to-face chip stacking structures, one approach is to use two sets of masks to create two different chips, one as the active-facing chip and the other as the active-facing chip. This approach has high process complexity and uncontrollable costs. Another approach is to create an additional set of conductive vias and connect both sets of conductive vias to the same driving circuit within the memory chip. However, this leads to complex internal wiring of the memory chip, increasing both process complexity and power consumption.

[0223] In another embodiment of this disclosure, see Figure 11 This illustration shows a structural schematic diagram of a memory chip 10 provided in an embodiment of this disclosure, which can be specifically understood as a cross-sectional schematic diagram of the active surface. For example... Figure 11 As shown, the memory chip 10 includes m channels ( Figure 11 (Taking m=4 as an example for illustration), m channels are arranged sequentially along the first direction. Each channel includes a first storage array area, a channel signal area, and a second storage array area distributed sequentially along the second direction. The center of each channel signal area coincides with the center of its respective channel.

[0224] The center of the active surface of the memory chip 10 and its adjacent area are defined as the global signal region 20, and the center point of the global signal region 20 coincides with the center point of the active surface; the m channels are symmetrical about the global signal region 20. Both the global signal region 20 and the channel signal regions are penetrated by a number of conductive vias along a third direction, and the third direction is perpendicular to the active surface.

[0225] Here, the conductive via can be a through-silicon via (TSV), specifically a vertical interconnect structure that penetrates a silicon wafer / chip. Alternatively, in other embodiments, it can be other conductive vias with conductive functions, without specific limitations. Furthermore, the conductive via can take the form of type 1 described above, or the form of type 2 described above.

[0226] For global signal region 20, each conductive via is used to transmit global signals, which are shared by all areas of the memory chip. Specifically, global signals include, but are not limited to: reset signals, power-on signals, stack identifier signals SID / CID, power-related signals Voltage Monitor, and timing-related signals Timing Aligner. In some cases, global signal region 20 may also refer to the pad area. Global signals can be test signals for Design for Test (DFT), through which the operating status of the internal circuitry and the transmission status of related signals can be determined. Furthermore, because the DFT pin pads in a logic chip are generally located in the middle of the chip, the conductive vias for global signals such as DFT are preferably located in a narrower area in the middle of the chip, i.e., ... Figure 3 The location of the global signal region 20 is shown. Conversely, for the channel signal region, each conductive via is used to transmit a channel signal, and each channel signal is only used by the corresponding channel.

[0227] Please see Figure 3 The active surface includes a first axis AA' and a second axis BB'. The first axis AA' is parallel to the first side of the logic chip 70, and the first axis AA' and the second axis BB' intersect each other perpendicularly at the center point of the active surface. Figure 3 In this embodiment, the first axis AA' extends along a first direction, and the second axis BB' extends along a second direction; in other embodiments, the first axis AA' may extend along a second direction, and the second axis BB' may extend along a first direction.

[0228] For the global signal region 20, the multiple conductive vias are divided into multiple conductive via groups. That is, the global signal region 20 is penetrated by n conductive via groups along a third direction, where n is a positive integer. Please refer to [link to relevant documentation]. Figure 4 Each conductive via group includes four normal conductive vias (D0, D1, D2, D3), and the first normal conductive via D0 and the second normal conductive via D1 are symmetrical about the first axis AA', the third normal conductive via D2 and the fourth normal conductive via D3 are symmetrical about the first axis AA', and the first normal conductive via D0 and the fourth normal conductive via D3 are symmetrical about the second axis BB'.

[0229] Please see Figure 4 The memory chip 10 also includes n selection circuits 30, and the internal circuitry of the memory chip 10 includes n internal port groups (In0 to In2). Due to space limitations, Figure 4 Only one group of conductive vias and one group of internal ports are shown.

[0230] The i-th selection circuit 30 is configured to receive and, based on the selection signal, electrically connect the four normal conductive vias in the i-th conductive via group to the four internal ports in the i-th internal port group, with the correspondence between the four normal conductive vias and the four internal ports determined based on the selection signal.

[0231] For ease of explanation, each i-th internal port group includes the i-th first internal port In0, the i-th second internal port In1In0, the i-th third internal port In3In1, and the i-th fourth internal port In3In2.

[0232] Please refer to Table 1. The i-th selection circuit is configured as follows: (1) If the selection signal is the first preset value, the first normal conductive via D0, the second normal conductive via D1, the third normal conductive via D2, and the fourth normal conductive via D3 in the i-th conductive via group are electrically connected to the i-th fourth internal port In3, the i-th third internal port In3, the i-th second internal port In1, and the i-th first internal port In0, respectively, i.e., case 1 in Table 1; (2) If the selection signal is the second preset value, the first normal conductive via D0, the second normal conductive via D1, the third normal conductive via D2, and the fourth normal conductive via D3 in the i-th conductive via group are electrically connected to the i-th second internal port In1, the i-th first internal port In0, the i-th fourth internal port In3, and the i-th third internal port In3, respectively, i.e., case 1 in Table 1; (3) If the selection signal is the second preset value, the first normal conductive via D0, the second normal conductive via D1, the third normal conductive via D2, and the fourth normal conductive via D3 in the i-th conductive via group are electrically connected to the i-th second internal port In1, the i-th first internal port In0, the i-th fourth internal port In3, and the i-th third internal port In3, respectively, i.e., case 1 in Table 1; Case 2 in 1; (3) If the selected signal is the third preset value, then the first normal conductive via D0, the second normal conductive via D1, the third normal conductive via D2, and the fourth normal conductive via D3 in the i-th conductive via group are electrically connected to the i-th third internal port In3, the i-th fourth internal port In3, the i-th first internal port In0, and the i-th second internal port In1, which is Case 3 in Table 1; (4) If the selected signal is the fourth preset value, then the first normal conductive via D0, the second normal conductive via D1, the third normal conductive via D2, and the fourth normal conductive via D3 in the i-th conductive via group are electrically connected to the i-th fourth internal port In3, the i-th third internal port In3, the i-th second internal port In1, and the i-th first internal port In0, which is Case 4 in Table 1.

[0235] Please refer to the above. Figure 2A or Figure 2BLogic chips and multiple memory chips 10 are stacked along a third direction to form a chip stack structure; in the chip stack structure, every four memory chips 10 form one stack unit. Each memory chip 10 has a chip location identifier (CID) and a chip location identifier (SID). The CID indicates the position of the memory chip 10 in its respective stack unit; the SID indicates the position of the stack unit to which the memory chip 10 belongs within its respective chip stack structure.

[0236] Taking a chip stacking unit consisting of one logic chip and eight memory chips 10 stacked together (each stacking unit consists of four memory chips 10, for a total of two stacking units) as an example, the CID has two sub-signals CID[1:0], the SID has two sub-signals SID[1:0], and the chip location identification code CID[1:0] is decoded from the chip location identification signal group CID0[3:0]. Specifically, during the normal operation phase of the memory chips 10, they are numbered from the logic chip side (i.e., from bottom to top), and the CID[1:0] and SID[1:0] of each chip are shown in Table 2. During the initialization phase of the memory chips 10, they are numbered from the side away from the logic chip (i.e., from top to bottom). This case is not shown for now, but it can be understood accordingly.

[0237] Table 2

[0238]

[0239] Specifically, in this embodiment, the different memory chips 10 are positioned differently in the chip stack structure. For ease of explanation, the active surface of each memory chip 10 (the plane containing the first and second directions) is divided into a low-order transmission region and a high-order transmission region. Please refer to [link to relevant documentation]. Figure 5A The arrow on each chip points to the high-order transmission area.

[0240] In this embodiment of the disclosure, the positions of the memory chips 10 are divided into four categories: the top surfaces of the memory chips in the first and third categories face upward along a third direction, and the top surfaces of the memory chips in the second and fourth categories face downward along a third direction; the active surface of each memory chip is divided into a low-level transmission region and a high-level transmission region, and the low-level transmission regions in the memory chips in the first category, the high-level transmission regions in the memory chips in the second category, the high-level transmission regions in the memory chips in the third category, and the low-level transmission regions in the memory chips in the fourth category are aligned along a third direction.

[0241] In one stacking method, please refer to Figure 5A(1) The first memory chip 11 is in the first type position, the second memory chip 12 is in the second type position, the third memory chip 13 is in the third type position, and the fourth memory chip 14 is in the fourth type position;

[0242] For another stacking method, please refer to Figure 5B (1) The first memory chip 11 is in the first type position, the second memory chip 12 is in the fourth type position, the third memory chip 13 is in the third type position, and the fourth memory chip 14 is in the second type position.

[0243] The storage chip 10 further includes a decoding circuit 21 configured to receive a chip location identification code CID[1:0]. If the chip location identification code CID[1:0] indicates a first type of location, the circuit outputs a selection signal with a first preset value; if the chip location identification code CID[1:0] indicates a second type of location, the circuit outputs a selection signal with a second preset value; if the chip location identification code CID[1:0] indicates a third type of location, the circuit outputs a selection signal with a third preset value; and if the chip location identification code CID[1:0] indicates a fourth type of location, the circuit outputs a selection signal that conforms to a fourth preset value.

[0244] In other embodiments, the decoding circuit 21 may also generate a selection signal based on CID0[3:0].

[0245] In some embodiments, see Figure 6 Each group of conductive vias also includes a first redundant conductive via R0, a second redundant conductive via R1, a third redundant conductive via R2 and a fourth redundant conductive via R3. Figure 6 We'll use a = 1 as an example for now, but a can take other positive integer values. For example... Figure 6 As shown, a first redundant conductive via R0 and a second redundant conductive via R1 are symmetrical about the first axis AA', a third redundant conductive via R2 and a fourth redundant conductive via R3 are symmetrical about the first axis AA', and a first redundant conductive via R0 and a fourth redundant conductive via R3 are symmetrical about the second axis BB'.

[0246] For each group of conductive vias, a first redundant conductive vias R0, a second redundant conductive vias R1, a first normal conductive vias D0 and a second normal conductive vias D1 constitute a repair unit, and a third redundant conductive vias R2, a fourth redundant conductive vias R3, a third normal conductive vias D2 and a fourth normal conductive vias D3 constitute another repair unit.

[0247] The selection circuit 30 is further configured to, when any normal conductive via fails, use other conductive vias of the same repair unit to replace the failed normal conductive via and electrically connect it to the corresponding internal port. For example, assuming the selection signal is a first preset value, if the first normal conductive via D0 is not failed, the selection circuit 30 electrically connects the first normal conductive via D0 to the first internal port In0; if the first normal conductive via D0 fails, it electrically connects other conductive vias of the same repair unit to the first internal port In0.

[0248] It should be noted that via failure refers to the failure of the signal transmission channel formed by the via and other vias aligned along a third direction (belonging to other memory chips). In other words, for multiple vias aligned along a third direction, damage to any one via will cause the signal transmission channel to fail, and the other vias will also fail even if they are not damaged.

[0249] Here, a normal conductive via refers to a conductive via designed from the outset to transmit valid signals, while a redundant conductive via refers to a conductive via designed from the outset not to transmit any signals. However, when any normal conductive via fails, a redundant conductive via can be converted into a normal conductive via to transmit valid signals, so that the memory can still function normally. That is, for the same repair unit, when any normal conductive via fails, the valid signal transmitted by the normal conductive via is switched to the next conductive via in the same repair unit along a preset switching direction. Specifically: (1) If the next conductive via being switched to is a redundant conductive via, the repair ends, and the redundant conductive via becomes a new normal conductive via; (2) If the next conductive via being switched to is another normal conductive via, the signal originally transmitted by the switched normal conductive via continues to be switched to its next conductive via along the preset switching direction.

[0250] Thus, via the selection circuit 30, any conductive via in any repair unit is electrically connected to the internal circuitry of the logic chip 10 when transmitting a valid signal, and is electrically isolated from the internal circuitry of the logic chip 10 when not transmitting a valid signal.

[0251] The following example, using a=1, provides a redundant repair logic example to better understand the foregoing explanation. However, this example is not the only solution. In this specific embodiment, each normal conductive via can be repaired via two other conductive vias; but this is merely an example. In other embodiments, more redundant conductive vias can be provided, or each normal conductive via can be repaired via an additional number of other conductive vias.

[0252] In some embodiments, see Figure 6The selection circuit 30 is specifically configured such that if the first normal conductive via D0 fails, a first redundant conductive via R0 or a fourth normal conductive via D3 is used to replace the first normal conductive via D0 and electrically connect it to the corresponding internal port; if the fourth normal conductive via D3 fails, a fourth redundant conductive via R3 or a first normal conductive via D0 is used to replace the fourth normal conductive via D3 and electrically connect it to the corresponding internal port; and if the second normal conductive via D1 fails, a second redundant conductive via R1 or a third normal conductive via D2 is used to replace the second normal conductive via D1 and electrically connect it to the corresponding internal port; and if the third normal conductive via D2 fails, a third redundant conductive via R2 or a second normal conductive via D1 is used to replace the third normal conductive via D2 and electrically connect it to the corresponding internal port.

[0253] It should be noted that if a normal conductive via is used to replace another failed normal conductive via, then another redundant conductive via is also needed to replace the fourth normal conductive via D3 in electrical connection to the corresponding internal port, until a redundant conductive via is enabled. For example, if the fourth normal conductive via D3 replaces the first normal conductive via D0 in electrical connection to the corresponding internal port, then it may also be necessary to enable the fourth redundant conductive via R3 in electrical connection to the fourth normal conductive via D3 in electrical connection to the corresponding internal port.

[0254] In this way, the repair unit in the logic chip 10 has a four-quadrant symmetry relationship, and the normal conductive vias therein also have a four-quadrant symmetry relationship. Thus, the chip stack structure formed by the logic chip and the memory chip 10 (which also has this characteristic) can achieve the signal rotation transmission effect through the direct connection configuration of the conductive vias. The parasitic resistance and parasitic capacitance are relatively small, as can be seen in the following description. At the same time, the redundancy repair function of the above structure can also be realized through the four-quadrant symmetrical repair unit, thereby improving the stability of the chip.

[0255] In one specific embodiment, please refer to Figure 7 The selection signals include a first selection signal Ch0 and a second selection signal Ch1. The i-th selection circuit 30 includes an i-th first selection circuit 31, an i-th second selection circuit 32, an i-th first signal output circuit 33, and an i-th second signal output circuit 34.

[0256] For the i-th first selection circuit 31, one side is coupled to the first normal conductive via D0, the fourth normal conductive via D3, the first redundant conductive via R0 and the fourth redundant conductive via R3 in the i-th conductive via group, and the other side is coupled to the i-th first secondary node Sec0 and the i-th fourth secondary node Sec3.

[0257] The i-th first selection circuit 31 is configured to receive and, based on the first via state parameter group and the first selection signal Ch0, electrically connect one of the coupled conductive vias to the i-th first secondary node Sec0, and electrically connect the other coupled conductive via to the i-th fourth secondary node Sec3.

[0258] For the i-th second selection circuit 32, one side is coupled to the second normal conductive via D1, the third normal conductive via D2, the second redundant conductive via R1 and the third redundant conductive via R2 in the i-th conductive via group, and the other side is coupled to the i-th second-level node Sec1 and the i-th third-level node Sec2.

[0259] The i-th second selection circuit 32 is configured to receive and, based on the second via state parameter group and the first selection signal Ch0, electrically connect one of the coupled conductive vias to the i-th second-level node Sec1, and electrically connect the other coupled conductive via to the i-th third-level node Sec2.

[0260] The i-th first signal output circuit 33 is configured to receive and, based on the second selection signal Ch1, electrically connect the i-th first primary node Sec0 to the i-th first internal port In0, and electrically connect the i-th fourth secondary node Sec3 to the i-th fourth internal port In3; or, electrically connect the i-th second primary node Sec1 to the i-th first internal port In0, and electrically connect the i-th third secondary node Sec2 to the i-th fourth internal port In3.

[0261] The i-th second signal output circuit 34 is configured to receive and, based on the second selection signal Ch1, electrically connect the i-th second secondary node Sec1 to the i-th second internal port In1, and electrically connect the i-th third secondary node Sec2 to the i-th third internal port In2; or, electrically connect the i-th first primary node Sec0 to the i-th second internal port In1, and electrically connect the i-th fourth secondary node Sec3 to the i-th third internal port In3.

[0262] Assuming that when a normal conductive via fails, it is preferentially repaired using another redundant conductive via; only if both the normal conductive via and the corresponding redundant conductive via fail will another normal conductive via be used for repair. The following provides a specific selection circuit.

[0263] Please see Figure 7 The i-th first selection circuit 31 includes the i-th first repair circuit 311, the i-th second repair circuit 312, and the i-th first selection output circuit 313;

[0264] For the i-th first repair circuit 311, one side is coupled to the first redundant conductive via R0, the first normal conductive via D0 and the fourth normal conductive via D3 in the i-th conductive via group, and the other side is coupled to the i-th first primary node Middle0; the first repair circuit 311 is configured to receive and, based on the i-th first via state parameter group, electrically connect one of the three coupled first normal conductive via D0, first redundant conductive via R0 and fourth normal conductive via D3 to the i-th first primary node Middle0;

[0265] For the i-th second repair circuit 312, one side is coupled to the first normal conductive via D0, the fourth normal conductive via D3, and the fourth redundant conductive via R3 in the i-th conductive via group, and the other side is coupled to the i-th fourth primary node Middle3; the second repair circuit 312 is configured to receive and, based on the i-th first via state parameter group, connect one of the three coupled to the i-th fourth primary node Middle3.

[0266] The i-th first selection output circuit 313 is configured to receive and select the first signal Ch0, and then electrically connect the i-th first primary node Middle0 to the i-th first secondary node Sec0, and electrically connect the i-th fourth primary node Middle3 to the i-th fourth secondary node Sec3; or, electrically connect the i-th fourth primary node Middle3 to the i-th first secondary node Sec0, and electrically connect the i-th first primary node Middle0 to the i-th fourth secondary node Sec3.

[0267] In one specific embodiment, the following premise is given: the first preset value refers to the selection signal Ch[1:0] = 00, the second preset value refers to the selection signal Ch[1:0] = 10, the third preset value refers to the selection signal Ch[1:0] = 11, and the fourth preset value refers to the selection signal Ch[1:0] = 01. For a feasible structure of the first selection output circuit 313, please refer to [link to relevant documentation]. Figure 8 .

[0268] like Figure 8As shown, each selection output circuit 313 may include four enable transmission gates. The first enable transmission gate is coupled between the first primary node Middle0 and the first secondary node Sec0; the second enable transmission gate is coupled between the first primary node Middle0 and the fourth secondary node Sec3; and the enable terminal of the first enable transmission gate receives the inverted signal of the first selection signal Ch0, while the enable terminal of the second enable transmission gate receives the first selection signal Ch0. The third enable transmission gate is coupled between the fourth primary node Middle3 and the first secondary node Sec0; the fourth enable transmission gate is coupled between the fourth primary node Middle3 and the fourth secondary node Sec3; and the enable terminal of the third enable transmission gate receives the first selection signal Ch0, while the enable terminal of the fourth enable transmission gate receives the inverted signal of the first selection signal Ch0. The structures of the first signal output unit 33 and the second signal output unit 34 are similar.

[0269] In one specific embodiment, the i-th first via state parameter group includes a first state parameter R0E, a second state parameter D0E, a third state parameter D3E, and a fourth state parameter R3E, which correspond one-to-one to indicate whether the first redundant conductive via R0, the first normal conductive via D0, the fourth normal conductive via D3, and the fourth redundant conductive via R3 in the i-th conductive via group are ineffective; when any state parameter is in an enabled state, it indicates that the corresponding conductive via is not ineffective; when any state parameter is in a disabled state, it indicates that the corresponding conductive via is ineffective.

[0270] Please see Figure 8 The i-th first repair circuit 311 includes a first switching unit 412, a second switching unit 422, a third switching unit 432, a first logic unit 411, a second logic unit 421, and a third logic unit 431;

[0271] The first logic unit 411 is configured to output a first control signal Ctr1 in an enabled state only when the state parameter group of the i-th first via meets the first preset condition; wherein, the first preset condition means that the first state parameter R0E is in an enabled state and the second state parameter D0E is in a disabled state, or that both the first state parameter R0E and the second state parameter D0E are in an enabled state and both the third state parameter D3E and the fourth state parameter R3E are in a disabled state; the first switching unit 412 is configured to control the i-th first redundant conductive via R0 to be electrically connected to the i-th first primary node Middle0 only when the first control signal Ctr1 is in an enabled state.

[0272] Thus, R0 replacing D0 (R0 is electrically connected to the first primary node Middle0) occurs in the following two cases: (1) R0 is not faulty and D0 is faulty, please refer to Figure 9A as well as Figure 9E(2) If R0 and D0 are not faulty but D3 and R3 are both faulty, then the faulty D0 needs to replace the faulty D3 and be electrically connected to the corresponding internal port. Therefore, R0 also needs to replace D0. Please refer to [link to relevant documentation]. Figure 9B .

In this case, the faulty D1 needs to replace the faulty D2 and be electrically connected to the corresponding internal port, so R1 also needs to replace D1.

In this case, the faulty D2 needs to replace the faulty D1 and be electrically connected to the corresponding internal port, so R2 also needs to replace D2.

[0305] Please see Figure 10 The eleventh logic unit 651 is configured to output the eleventh control signal Ctr11, which is enabled, only under the eleventh preset condition of the eleventh state parameter group of the i-th second via. The eleventh preset condition means that the seventh state parameter D2E is enabled, and at least one of the sixth state parameter D1E and the fourth state parameter R3E is enabled. The eleventh switching unit 652 is configured to control the i-th third normal conductive via D2 to be electrically connected to the i-th fourth primary node only when the eleventh control signal Ctr11 is enabled.

[0306] Thus, D2 can function normally (D2 is electrically connected to the third primary node Middle2) under the following conditions: (1) D2 is not faulty and at least one of D1 and R1 is not faulty.

[0307] Please see Figure 10 The twelfth logic unit 661 is configured to output the twelfth control signal Ctr12, which is enabled, only under the twelfth preset condition of the twelfth state parameter group of the i-th second via. The twelfth preset condition means that the eighth state parameter R2E and the seventh state parameter D2E are both disabled, and the sixth state parameter D1E is enabled. The twelfth switching unit 662 is configured to control the i-th second normal conductive via D1 to be electrically connected to the i-th fourth primary node only when the twelfth control signal Ctr12 is enabled.

[0308] Thus, D1 replaces D2 and is electrically connected to the corresponding internal port in the following situation (D1 is electrically connected to the third primary node Middle2): D1 and R1 both fail and D2 does not fail.

[0309] In a specific embodiment, referring to FIG9, when the enable state is high and the disable state is low, the seventh logic unit 611 includes a seventh NOT gate 701, a seventh AND gate 702 and a seventh OR gate 703; the eighth logic unit 621 includes an eighth AND gate 711 and an eighth OR gate 712; the ninth logic unit 631 includes a ninth NOT gate 721 and a ninth AND gate 722; the tenth logic unit 641 includes a tenth NOT gate 731, a tenth AND gate 732 and a tenth OR gate 733; the eleventh logic unit 651 includes an eleventh AND gate 741 and an eleventh OR gate 742; and the twelfth logic unit 631 includes a twelfth NOT gate 751 and a twelfth AND gate 752.

The other input of the twelfth AND gate 752 receives the sixth state parameter D1E, and the twelfth AND gate 752 outputs the twelfth control signal Ctr12.

[0312] It should also be noted that the conductive vias mentioned above can at least be embodied as through-silicon vias (TSVs), specifically a vertical interconnect structure that penetrates the silicon wafer / memory chip 10, for example... Figure 1 Type 1 in the above; of course, conductive vias can also be used. Figure 1 Type 2 in the diagram, together with the contact structure, enables signal transmission. In other embodiments, other electrical connection structures can also be selected as conductive vias.

[0313] Conductive vias can be fabricated using one or more of the following processes: pre-via, mid-via, post-via, and back-via. Pre-via refers to a via fabrication process where the via structure is created before the device, such as a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), is manufactured. Mid-via fabrication involves creating the via structure during the manufacturing process, often after device formation but before the stack-up. Post-via fabrication involves forming the via from the front side of the wafer after the back-end of line (BEOL) process. Back-via fabrication involves creating the via structure from the back side of the wafer after the BEOL process. In other words, pre-via fabrication can mean creating the via first, then the circuitry; mid-via fabrication can mean creating the circuitry and part of the metal layer first, then the via, and finally the remaining via; post-via and back-via fabrication can mean creating the circuitry and metal layer first, then the via.

[0314] In summary, the present disclosure provides a memory chip that transmits four different global signals through four different normal conductive vias, resulting in high signal transmission efficiency. Furthermore, each of the four different normal conductive vias corresponds to four redundant conductive vias, enabling redundancy repair. The chip stack structure formed by this memory chip and a logic chip (which also possesses this characteristic) achieves signal rotation transmission through the direct connection configuration of the conductive vias, resulting in relatively low parasitic resistance and capacitance.

Both the global signal region 20 and the channel signal regions are penetrated by a number of conductive vias along a third direction, and the third direction is perpendicular to the active surface. For the global signal region 20, each conductive via is used to transmit a global signal, and the global signal is shared by all areas of the memory chip 10; for the channel signal regions, each conductive via is used to transmit a channel signal, and each channel signal is only used by the corresponding channel.

[0317] Specifically, the global signal region 20 of the logic chip 70 and the memory chip 10 have the same area, but the active surface area of ​​the logic chip 70 may be greater than or equal to the active surface area of ​​the memory chip 10.

[0359] This disclosure provides a logic chip 70 that transmits four different global signals through four different normal conductive vias, resulting in high signal transmission efficiency. Simultaneously, each of the four different normal conductive vias corresponds to four redundant conductive vias, enabling redundancy repair. The chip stack structure formed by this memory chip and the logic chip (which also has this characteristic) achieves signal rotation transmission through the direct connection configuration of the conductive vias, resulting in relatively small parasitic resistance and capacitance.

[0360] In another embodiment of this disclosure, see [reference needed]. Figure 16 This illustrates a schematic diagram of the composition of a chip stacking structure 90 provided in an embodiment of this disclosure. For example... Figure 16 As shown, the chip stacking structure 90 includes the aforementioned logic chip 70 and at least one stacking unit, and the logic chip 70 and at least one stacking unit are stacked sequentially along a third direction; each stacking unit includes a first memory chip 11, a second memory chip 12, a third memory chip 13 and a fourth memory chip 14 stacked along a third direction; the logic chip 70, and the first memory chip 11, the second memory chip 12, the third memory chip 13 and the fourth memory chip 14 are all based on the aforementioned memory chip 10.

[0361] For each stacking unit, the first memory chip 11 and the second memory chip 12 are stacked face-to-face, the second memory chip 12 and the third memory chip 13 are stacked back-to-back, and the third memory chip 13 and the fourth memory chip 14 are stacked face-to-face; the first memory chip 11 and the logic chip 70 in the first stacking unit are stacked back-to-face, or the first memory chip 11 and the logic chip 70 in the first stacking unit are stacked back-to-back.

[0362] In this embodiment of the disclosure, face-to-face stacking means that the top surfaces of two chips are approximately aligned along a third direction; back-to-back stacking means that the top surfaces of two chips are approximately aligned along a third direction; face-to-back stacking means that the top surface of one chip is approximately aligned with the bottom surface of another chip along a third direction. Unless otherwise specified, "chip" can refer to either a logic chip or a memory chip. In the chip stacking structure 90, the center points of all chips, the first axis AA' and the second axis BB' of the top surface are aligned along a third direction.

[0363] It should be noted that, in one possibility, for two chips connected face-to-face, the bonding surfaces (the positions where the conductive vias are aligned along the third direction) are electrically connected through a hybrid bonding structure (also known as bonding pillars); for two chips connected back-to-back or back-to-face, the bonding surfaces (the positions where the conductive vias are aligned along the third direction) are electrically connected through conductive bumps (UBumps, also known as microbumps).

[0364] In another possibility, for two chips connected face-to-face, or for two chips connected back-to-back, or for two chips connected back-to-face, the bonding surfaces (positions where the conductive vias are aligned along a third direction) of both are connected by a hybrid bonding structure.

[0365] In another possibility, for two chips connected face-to-face, or for two chips connected back-to-back, or for two chips connected back-to-face, the mating surfaces (positions where the conductive vias are aligned along a third direction) of both are connected by conductive bumps.

[0366] Here, the above chip can refer to either logic chip 70 or memory chip 10.

[0367] It should be noted that, compared to conductive bump technology, face-to-face bonding using hybrid bonding technology allows for a tighter fit between adjacent memory chips, virtually eliminating gaps. This significantly reduces the height of the chip stack structure, which is one of the advantages of face-to-face stacking. Of course, two memory chips connected back-to-back can also be linked using a hybrid bonding structure, but its connection performance is weaker than that achieved through conductive bump technology. Therefore, in this embodiment, the chip stack structure 90 supports face-to-face stacking, resulting in better performance.

[0368] As mentioned above, the logic chip 70 or each memory chip can be divided into a high-order transmission region and a low-order transmission region. In the following figures, the arrows for each chip are uniformly located in the high-order transmission region of the chip. In particular, the high-order transmission region and low-order transmission region in this embodiment of the disclosure are merely two regions that distinguish the memory chip, and do not have any other additional limitations. They are not related to the high-order data and low-order data commonly referred to in the data transmission process.

[0369] When the logic chip 30 and the first memory chip 11 are stacked back-to-back and the logic chip 30 and the fourth memory chip 14 are arranged in the same way, a first specific implementation method and a second specific implementation method are provided; when the logic chip 30 and the first memory chip 11 are stacked back-to-back and the logic chip 30 and the second memory chip 12 are arranged in the same way, a third specific implementation method and a fourth specific implementation method are provided, as detailed below.

[0370] In the first specific embodiment, such as Figure 17A As shown, assuming that the logic chip 70 and each memory chip's respective first axis AA' divides the chip into a high-order transmission region and a low-order transmission region (i.e., the first axis AA' extends along the first direction), the high-order transmission region of the logic chip 70, the high-order transmission region of the first memory chip 11, the low-order transmission region of the second memory chip 12, the low-order transmission region of the third memory chip 13, and the high-order transmission region of the fourth memory chip 14 are aligned along the third direction; the low-order transmission region of the logic chip 70, the low-order transmission region of the first memory chip 11, the high-order transmission region of the second memory chip 12, the high-order transmission region of the third memory chip 13, and the low-order transmission region of the fourth memory chip 14 are aligned along the third direction.

[0371] At this point, according to the aforementioned classification rules: the top surface of the memory chips in the first and third categories faces upward along the third direction, and the top surface of the memory chips in the second and fourth categories faces downward along the third direction; the active surface of each memory chip is divided into a low-level transmission region and a high-level transmission region, and the low-level transmission region in the memory chip in the first category, the high-level transmission region in the memory chip in the second category, the high-level transmission region in the memory chip in the third category, and the low-level transmission region in the memory chip in the fourth category are aligned along the third direction.

[0372] At this time, the first memory chip 11 is in the first type position, the second memory chip 12 is in the second type position, the third memory chip 13 is in the third type position, and the fourth memory chip 14 is in the fourth type position.

[0373] In the second specific embodiment, such as Figure 18A As shown, assuming that the second axis BB' of each logic chip 70 and each memory chip divides the chip into a high-order transmission region and a low-order transmission region (i.e., the second axis BB' extends along the first direction), the high-order transmission region of logic chip 70, the low-order transmission region of the first memory chip 11, the low-order transmission region of the second memory chip 12, the high-order transmission region of the third memory chip 13, and the high-order transmission region of the fourth memory chip 14 are aligned along the third direction; the low-order transmission region of logic chip 70, the high-order transmission region of the first memory chip 11, the high-order transmission region of the second memory chip 12, the low-order transmission region of the third memory chip 13, and the low-order transmission region of the fourth memory chip 14 are aligned along the third direction.

[0374] Similarly, the first memory chip 11 is a first-class position, the second memory chip 12 is a second-class position, the third memory chip 13 is a third-class position, and the fourth memory chip 14 is a fourth-class position.

[0375] Please see Figure 17B or Figure 18B For the first and second specific embodiments, each through hole has the following alignment relationship:

[0378] The second normal conductive via D1 in the i-th conductive via group of logic chip 70, the third normal conductive via D2 in the i-th conductive via group of each first memory chip 11, the fourth normal conductive via D3 in the i-th conductive via group of each second memory chip 12, the first normal conductive via D0 in the i-th conductive via group of each third memory chip 13, and the second normal conductive via D1 in the i-th conductive via group of each fourth memory chip 14 are aligned along a third direction and form a normal signal transmission channel; assuming it is used to transmit SignalC;

[0379] The first normal conductive via D0 in the i-th conductive via group of logic chip 70, the fourth normal conductive via D3 in the i-th conductive via group of each first memory chip 11, the third normal conductive via D2 in the i-th conductive via group of each second memory chip 12, the second normal conductive via D1 in the i-th conductive via group of each third memory chip 13, and the first normal conductive via D0 in the i-th conductive via group of each fourth memory chip 14 are aligned along a third direction and form a normal signal transmission channel, assuming it is used to transmit SignalD.

[0380] against Figure 17AFor a schematic diagram of the signal transmission of the / B chip stacking structure, please refer to [link / reference]. Figure 19 , Figure 18A In the chip stacking structure of / B, only the connection relationship between the internal ports and conductive vias in the logic chip 70 is different. That is to say, regardless of... Figure 17A / B or Figure 18A / B, the correspondence between the four internal ports and conductive vias, and the specific signals in each chip is shown in Table 3 below. Although the first memory chip 11 to the fourth memory chip 14 adopt different placement methods, the first internal port In0 of each chip receives the same signal SignalA, the second internal port In1 of each chip receives the same signal SignalB, the third internal port In2 of each chip receives the same signal SignalC, and the fourth internal port In3 of each chip receives the same signal SignalD. In particular, in Figure 19 In this context, the internal ports / signal ports are coupled to the corresponding conductive vias rather than being directly electrically connected. For example, the first internal port In0 in the first memory chip 11 is coupled to the first conductive via D0, and so on.

[0405]

[0406] At the same time, from Figures 17A-22BIt can be seen that for the chip stack structure 90, the signal transmission path from bottom to top will be similar to the following form: the fourth conductive via D3 in the logic chip 70 — the first conductive via D0 in the first memory chip 11 — the second conductive via D1 in the second memory chip 12 — the third conductive via D2 in the third memory chip 13 — the fourth conductive via D3 in the fourth memory chip 14… . In other words, for the chip stack structure 90, from a physical point of view, the conductive vias are still in a direct connection configuration. However, from the absolute position of the conductive vias on the active surface, the conductive vias can also be regarded as a functional rotation configuration. That is, a signal transmission effect similar to that in Figure 2 (i.e., a rotational transmission effect such as conductive via D0-conductive via D1-conductive via D2-conductive via D3…) is achieved through a physically direct connection configuration. In short, Figure 2B The chip stacking structure 90 in the present invention requires a physical spiral structure, which necessarily includes lateral interconnection structures. However, the chip stacking structure 90 in this embodiment is physically a direct connection structure, which does not require lateral interconnection structures. This significantly reduces parasitic resistance and greatly improves transmission speed and transmission performance.
