In an embodiment, the functional circuitry 110 and the cache circuitry 112 form a processor and are in signal communication with the first interface circuitry 120. For example, the processor is connected to the first interface circuitry 120 to send or receive signals through the first interface circuitry 120 in order to communicate with the second semiconductor die 200.

The transceiver 124 and the receiver 126 are connected to the first bonding component 130 in a one-to-one manner to establish signal transmission with the second semiconductor die 200. In some embodiments, the interface logic circuit 122 is configured to provide control logic for built-in self-test (BIST), training, repair, parity check functions, and design-for-testability (DFT) logic.
[0033] In some embodiments, the first interface circuit 120 includes flip-flop (FF) units, multiplexers, and other components for establishing interconnection circuits to the second semiconductor die 200. The multiplexers in some embodiments are of a double data rate (DDR) type based on the input data at the flip-flops. Figure 3 As shown, a single clock is provided by the first interface circuit 120 and the second interface circuit 220. The timing of the flip-flop and the multiplexer is controlled by the single clock.
[0034] In some embodiments, the first interface circuit 120 can receive instructions according to the intention of the core circuit (e.g., functional circuit 110) of the first semiconductor die 100 and provide output to the second semiconductor die 200 via the transceiver 124 and the corresponding bonding component 130.

The first interface circuit 120 may also receive a response from the second semiconductor die 200 via the corresponding bonding component 130 and receiver 126, and then transmit the data Rx_data inward to the core circuit (e.g., functional circuit 110) of the first semiconductor die 100.
[0035] In this example, see Figures 1 to 3 The second semiconductor die 200 includes a functional circuit 210, a second interface circuit 220, and a second bonding component 230. The second functional circuit 210 may include: Figure 2 The static random access memory circuit shown in FIG. Figure 3As shown, the second interface circuit 220 includes an interface logic circuit 222, a transceiver 224, and a receiver 226.

Similarly, the transceiver 224 in the second interface circuit 220 is connected to the corresponding receiver 126 in the first interface circuit 120 via the corresponding bonding component 130 and the corresponding bonding component 230. In addition, the timing of the second interface circuit 220 is controlled by a single clock. Figure 3 As shown, the interface logic circuit 222 can provide a second semiconductor die 220 (eg, Figure 1 As shown) outputs a response, for example, data Rx_data, and receives data Tx_data from the other second semiconductor die 220.
[0036] Figure 4 Schematically illustrates the configuration of the interface of a semiconductor device according to some embodiments of the present disclosure. Figure 4 In the embodiment, semiconductor device 1000 includes a first semiconductor die 100 and a second semiconductor die 200. Specifically, first semiconductor die 100 and second semiconductor die 200 are interconnected by interface 300. First semiconductor die 100 may include functional circuit 110, first interface circuit 120, and first bonding component 130. Second semiconductor die 200 may include functional circuit 210, second interface circuit 220, and second bonding component 230. Figure 4 The component configuration of the interface 300 is intended to be presented, and the configuration of the functional circuit 110 and the functional circuit 210 is not limited to the relationship shown in the figure.
[0037] In this embodiment, the first bonding component 130 can be configured at a predetermined pitch determined based on the bonding technology. Specifically, the first bonding component 130 is configured in the first bonding array region R130. The first interface circuit 120 is configured in a region that is smaller than the first bonding array region R130 and is substantially entirely located within the first bonding array region R130. As described above, the first bonding component 130 is connected to the transceiver 124 and the receiver 126 in the first interface circuit 120 in a one-to-one manner, and the pitch of the transceiver 124 and the receiver 126 can be smaller than the pitch of the first bonding component 130. In some embodiments, a portion of the first interface circuit 120 overlaps with one or more of the first bonding components 130. In this embodiment, the functional circuit 110 communicates signals with the first interface circuit 120. In some embodiments, a portion of the functional circuit 110 can be configured within the first bonding array region R130 and / or can overlap with one or more of the first bonding components 130.
[0038] The second bonding component 230 can be arranged at a predetermined pitch determined by the bonding technology. Specifically, the second bonding component 230 is arranged in the second bonding array region R230. The second bonding component 230 can be arranged corresponding to the first bonding component 130, such that the second bonding array region R230 is substantially a mirror image of the first bonding array region R130. Therefore, the second bonding component 230 is connected to the first bonding component 130 in a one-to-one manner. The second interface circuit 220 is arranged in an area smaller than the second bonding array region R230 and is substantially entirely located within the second bonding array region R230. As described above, the second bonding component 230 is connected to the transceiver 224 and the receiver 226 in the second interface circuit 220 in a one-to-one manner. The pitch between the transceiver 224 and the receiver 226 can be smaller than the pitch of the second bonding component 230. In some embodiments, a portion of the second interface circuit 220 overlaps with one or more portions of the second bonding component 230. In this embodiment, the functional circuit 210 communicates signals with the second interface circuit 220. In some embodiments, the functional circuit 210 may be disposed within the second bonding array region R230 and / or may overlap with one or more of the second bonding elements 230 .
[0039] In some embodiments, the configuration area of the first interface circuit 120 may be independent of the configuration of the first bonding component 130, and the configuration area of the second interface circuit 220 may be independent of the configuration of the second bonding component 230. For example, Figure 5 and Figure 6 Schematically illustrates the configuration of interface circuits and bonding components according to some embodiments of the present disclosure. Figure 5 In the embodiment, the interface circuit 20 may refer to the first interface circuit 120 or the second interface circuit 220 in the aforementioned embodiment, the bonding component 30 may refer to the first bonding component 130 or the second bonding component 230 in the aforementioned embodiment, and the bonding array area R1 may refer to the first bonding array area R130 or the second bonding array area 230 in the aforementioned embodiment. The bonding components 30 are arranged in a 5×5 array at a pitch P1, and the bonding components 30 are arranged in the bonding array area R1 having an area A1. The interface circuit 20 is configured in a prescribed area R2 having an area A2. As described in the previous embodiment, the interface circuit 20 may include an interface logic circuit, a transceiver, and a receiver that can be manufactured using a semiconductor manufacturing process at the nanometer level or smaller. Therefore, the physical implementation of the interface circuit 20 requires a smaller space. As Figure 5 As shown, area A2 is smaller than area A1. In this embodiment, interface circuit 20 is completely configured within bonding array region R2. In some embodiments, other circuits can be configured in the space between the boundaries of area A2 and area A1 to optimize the space utilization of the semiconductor device.
[0040] In such Figure 6 In another embodiment shown, the bonding elements 30 are arranged in a 5×5 array at a pitch P2, and the bonding elements 30 are arranged in a bonding array region R3 having an area A3. Figure 5 and Figure 6 , pitch P2 is greater than pitch P1 and area A3 is greater than area A2, but interface circuit 20 is still configured within the specified region R2 of area A2. Notably, interface circuit 20 can be adapted to various designs of the bonding array region without reconfiguring the components within interface circuit 20. In other words, the configuration of interface circuit 20 can be independent of the configuration of the corresponding bonding component 30. In some embodiments, other circuits can be configured in the space between the boundaries of area A2 and area A3 to optimize space utilization of the semiconductor device.

Figure 7 As shown, semiconductor die 500 includes substrate 502, electronic components of functional circuit 510, interface circuit 520, bonding component 530, and electronic components of interconnect wiring structure 504. Substrate 502 can be a semiconductor substrate including an isolation region or a semiconductor substrate. The electronic components for functional circuit 510 and the electronic components for interface circuit 520 are formed in substrate 502. Bonding component 530 is electrically connected to the electronic components in interface circuit 520 via interconnect wiring structure 504.
[0042] The electronic components for functional circuit 510 and the electronic components for interface circuit 520 may include active components such as transistors, passive components such as capacitors, resistors, etc., or a combination thereof. In some embodiments, the electronic components for functional circuit 510 and the electronic components for interface circuit 520 may be partially integrated into substrate 502 and manufactured using nanoscale or smaller semiconductor manufacturing processes.

In some embodiments, the bonding component 530 includes microbumps formed in the form of conductive balls / pillars, etc.
[0044] In this embodiment, some electronic components of the interface circuit 520 are electrically connected to corresponding bonding components 530 via the interconnect wiring structure 504. These electronic components include a transceiver and a receiver. In some embodiments, a portion of the electronic components of the interface circuit 520 overlaps with one or more of the bonding components 530. Specifically, the bonding components 530 are disposed within the bonding array region R530, and the interface circuit 520 is disposed within the bonding array region R530. The interface circuit 520 occupies a smaller area than the bonding array region R530, and the area between the outermost components of the interface circuit 520 and the boundary of the bonding array region R530 can be used for other chip-level layout and routing to optimize the pitch utilization of the substrate 502.
[0045] Functional circuit 510 can be configured adjacent to interface circuit 520, and a portion of functional circuit 510 can be located within bonding array region R530. In some embodiments, a portion of the electronic components of functional circuit 510 overlap with one or more bonding components 530. Functional circuit 510 can be in signal communication with interface circuit 520, such that electrical signals from functional circuit 510 can be transmitted to bonding component 530 via interface circuit 520, and signals input from bonding component 530 can be transmitted to functional circuit 510 via interface circuit 520.
[0046] The interconnect wiring structure 504 includes multiple metal layers Mx that establish interleaved signal transmission paths between the electronic components of the interface circuit 520 and the bonding assembly 530. The configuration of the electronic components of the interface circuit 520 can be independent of the configuration of the corresponding bonding assembly 530. For example, when viewed from a top view, the electronic components (transceivers or receivers) of the interface circuit 520 and the corresponding bonding assembly 530 for transmitting the same signal can be located in two separate locations, while other components (transceivers or receivers) of the interface circuit 520 and the corresponding bonding assembly 530 can be located in two separate locations. The interface circuit 520 and / or the bonding assembly 530 can be located between two separate locations. In an alternative embodiment, two adjacent electronic components (transceivers or receivers) of the interface circuit 520 can be separated by a pitch that is smaller than the pitch of the two corresponding bonding assemblies 530 to which they are connected.
[0047] The structure of the semiconductor die 500 may be considered as an embodiment of the first semiconductor die 100 or the second semiconductor die 200 described in the previous embodiments. For example, the functional circuit 510 may be Figures 2 to 4 In the embodiment of the functional circuit 110 or the functional circuit 210 shown, the interface circuit 520 may be Figures 2 to 4 In the embodiment of the first interface circuit 120 or the second interface circuit 220 shown, the bonding component 530 may be Figure 3The embodiment of the first bonding component 130 or the second bonding component 230 shown. Therefore, the interface circuit 520 and the bonding component 530 can be Figures 1 to 4 A portion of the interface 300 is shown. In addition, Figure 5 and Figure 6 The illustrated configuration of the interface circuit 20 and the bonding assembly 30 can be adapted to the structure of the semiconductor die 500 , making the interface circuit 520 compatible with various bond array designs.

The second interface circuit 520B is disposed within the second bonding array region R530B. The interface logic circuit, the transceiver, and the receiver in the second interface circuit 520B are disposed within the second bonding array region R530B. The transceiver and the receiver in the second interface circuit 520B are electrically connected to the second bonding element 530B, respectively. The pitch of the transceiver and the receiver in the second interface circuit 520B are smaller than the pitch of the second bonding element 530B. A portion of the second interface circuit 520B overlaps with one or more of the second bonding elements 530B.
[0056] In some embodiments, the method for configuring the interface 600 of the semiconductor device 2000 may include providing a first bonding array region R530A for configuring the first bonding component 530A implemented in the first semiconductor die 500A. In some embodiments, the first bonding array region R530A may be determined based on a specified rule for arranging the first bonding components 530A at a pitch. For example, the first bonding array region R530A may be configured to arrange the first bonding components 530A at a pitch ranging from 6 microns to 16 microns, but the present invention is not limited thereto. In other alternative embodiments, the pitch or the first bonding components 530A may be determined based on the design of the product.
[0057] Subsequently, the method further provides a first interface circuit 520A implemented within a first bonding array region R530A in the first semiconductor die 500A. The first interface circuit 520A may include interface logic circuitry, a transceiver, and a receiver fabricated using a semiconductor manufacturing process. The electronic components in the first interface circuit 520A may have dimensions as small as approximately nanometers. Typically, the dimensions and connections of the electronic components in the first interface circuit 520A are predetermined, thereby determining the area within which the interface circuit 520A is configured.
[0058] In this embodiment, the first interface circuit 520A is connected via Figure 8 The illustrated interconnect wiring structure 504A is electrically connected to the corresponding first bonding element 530A, providing a path for signal transmission. Therefore, the first interface circuit 520A is configured within the first bonding array region R530A, regardless of the relative position of the first bonding element 530A. Furthermore, the same specifications for the size and connection relationships of the electronic components in the first interface circuit 520A are compatible with various pitch designs of the first bonding element 530A, providing flexible design rules for manufacturing the first semiconductor die 500A of the semiconductor device 2000. Since the first interface circuit 520A requires a smaller area, the substrate has more space for other circuits or components, increasing the design flexibility of the semiconductor device 2000.
[0059] The method also includes providing a second interface circuit 520B and a second bonding component 530B implemented in a second semiconductor die 500B. Similar to the first semiconductor die 500A, the second bonding component 530B in the second semiconductor die 500B can be configured in a second bonding array region R530B, and the second interface circuit 520B in the second semiconductor die 500B can be configured within the second bonding array region R530B. Furthermore, the configuration of the second interface circuit 520B can be independent of the configuration of the second bonding component 530B. Therefore, the same dimensions and component connection relationships in the second interface circuit 520B are compatible with various pitch designs of the second bonding component 530B. In some embodiments, the second bonding array region R530B can be used to arrange the second bonding components 530B at a pitch ranging from 6 microns to 16 microns, but the present disclosure is not limited thereto. In other alternative embodiments, the pitch or the second bonding component 530B can be determined based on the design of the product.
[0060] The method further includes bonding the first bonding element 530A to the second bonding element 530B. In an embodiment, the second bonding array region R530B may be substantially a mirror image of the first bonding array region R530A, and the first semiconductor die 500A and the second semiconductor die 500B are bonded in a face-to-face manner. Figure 8As shown, first semiconductor die 500A further includes an internal interconnect wiring structure 504A that establishes a path for signal transmission, so the configuration of first interface circuit 520A can be independent of the configuration of first bonding element 530A. Similarly, second interface circuit 520B in second semiconductor die 500B is electrically connected to second bonding element 530B via internal interconnect wiring structure 504B, and the configuration of second interface circuit 520B can be independent of the configuration of second bonding element 530B.
[0061] In summary, the semiconductor device according to some embodiments of the present disclosure includes a plurality of semiconductor dies bonded in a face-to-face manner. The interface between the semiconductor dies includes an interface circuit and a bonding component formed in each semiconductor die. The interface circuit can be configured in a determined area compatible with various pitch designs of the bonding component. Therefore, the configuration of the interface is flexible. In addition, the interface circuit is concentrated in the determined area, so that the substrate implemented together with the interface circuit can have a flexible pitch utility.
