[0048] It is important to understand that the following content provides many different embodiments or examples to implement different components of the provided subject. Specific examples of the various components and their arrangements are described below to simplify the explanation. Of course, these are merely examples and are not intended to limit the embodiments of this utility model. For example, the dimensions of the components are not limited to the range or values ​​of one embodiment of this disclosure, but may depend on the processing conditions and / or required nature of the components. Furthermore, the embodiments in the following description where the first component is formed above or on the second component include those where the first and second components are formed in direct contact, and may also include embodiments where additional components may be formed between the first and second components, such that the first and second components are not in direct contact. In addition, different examples in the disclosure may use repeated reference numerals and / or words. These repeated numerals or words are for simplification and clarity purposes and are not intended to limit the relationships between the various embodiments and / or the described appearance structures.

[0049] Furthermore, to facilitate the description of the relationship between one element or component and another (or multiple elements or components) in the accompanying drawings, spatially related terms such as "below," "under," "lower part," "above," "upper part," and similar terms may be used. In addition to the orientations shown in the drawings, spatially related terms also cover different orientations of the device during use or operation. The device may also be positioned otherwise (e.g., rotated 90 degrees or located in other orientations), and the descriptions using the spatially related terms will be interpreted accordingly.

[0050] Packaging technologies (such as 3D integrated circuits (3D-ICs) and chip-on-a-bed (CoWoS) technologies) involve stacking semiconductor chips (also known as integrated circuits or dies) together to enhance performance while reducing footprint. Semiconductor chips can take many forms. In one example, a semiconductor chip includes a chip substrate, chip components formed on the chip substrate (e.g., passive electronic components such as resistors, capacitors, and inductors, and active electronic components such as transistors), conductive layers interconnecting the chip components, and interconnect structures formed on the bottom and / or top surfaces of the conductive layers.

[0051] Interconnect structures are used in semiconductor packaging to form electrical connections between stacked semiconductor chips or between semiconductor chips and interposers or substrates. They can be combinations of microbumps, solder balls, copper pillars, metal and dielectric interconnect structures, other forms of interconnects created through, for example, hybrid bonding, tape-automated bonding (TAB), wire bonding, flip-chip bonding, other suitable interconnect structures, or combinations thereof. For example, an electrical connection between a pair of semiconductor chips in a package can be established by aligning an interconnect structure of one semiconductor chip with a node on the other semiconductor chip. The interconnect structure is then bonded to the node using a reflow soldering process. Next, an insulating material is used to fill the gap between the interconnect structure and the semiconductor chip to provide a stronger mechanical connection between the semiconductor chips. The package then undergoes a cooling phase to solidify the solder joints, thereby forming a permanent and reliable electrical connection between the semiconductor chips.

[0052] In some examples, during the fabrication of a device having this packaging technology, the semiconductor chips of the device are oriented or aligned relative to each other to ensure proper bonding using interconnect structures. This step in the fabrication process is prone to error. If misalignment occurs between the semiconductor chips, the interconnect structure connected to a node of one of the semiconductor chips (e.g., receiving a supply voltage) may inadvertently connect to, for example, an electrical ground node of another semiconductor chip, resulting in an electrical short circuit in the device. The systems and methods described in some examples herein mitigate this drawback by symmetrically arranging the interconnect structures of the semiconductor chips relative to the x-axis, y-axis, or both. Regardless of the orientation of the semiconductor chips, this ensures proper bonding of the semiconductor chips to the substrate, interposer, or another semiconductor chip, which will be described in detail below.

[0053] Figure 1 A cross-sectional schematic diagram of an exemplary device 100 is provided for various embodiments of the present invention.

The package substrate 110 may have horizontal conductors (or interconnect structures) therein, vertical conductors (or vias) therein, and / or through-silicon vias (TSVs) passing through it, and conductive bumps 110' on its bottom surface. Examples of materials used for the package substrate 110 include silicon, germanium, group III-V semiconductor materials, other suitable semiconductor materials, and the aforementioned alloys. The horizontal conductors, vertical conductors, TSVs, and conductive bumps 110' may be made of copper, aluminum, nickel, barrier metals (e.g., titanium, tungsten, and tantalum), gold, tin, other suitable conductive materials, or the aforementioned alloys. In some embodiments, the package substrate 110 is omitted from the device 100.

[0054] Intermediate layer 120 is mounted on package substrate 110 and includes intermediate substrate 120a, redistribution layer (RDL) 120b formed in intermediate substrate 120a, and intermediate bumps 120c formed on the bottom surface of intermediate substrate 120a. Intermediate layer 120 may further include horizontal conductors (or interconnect structures), vertical conductors (or vias), and / or through-silicon vias (TSVs) embedded in intermediate substrate 120a. Examples of materials used for intermediate substrate 120a may be silicon, germanium, group III-V semiconductor materials, other suitable semiconductor materials, and alloys thereof. Redistribution layer 120b, horizontal conductors, vertical conductors, TSVs, and intermediate bumps 120c may be made of copper, aluminum, nickel, barrier metals (e.g., titanium, tungsten, and tantalum), gold, tin, other suitable conductive materials, or alloys thereof.

[0055] Semiconductor chip 130 includes a chip substrate 130a, a device layer 130b, a conductive layer 130c, and multiple interconnect structures 130d. Examples of materials used for the chip substrate 130a include silicon, germanium, group III-V semiconductor materials, other suitable semiconductor materials, and the aforementioned alloys. The device layer 130b is formed on the bottom surface of the chip substrate 130a and includes multiple chip components, such as passive electronic components (e.g., resistors, capacitors, and inductors) and active electronic components (e.g., transistors). The conductive layer 130c is formed above the chip substrate 130a and the device layer 130b, interconnecting the chip components of the device layer 130b, and includes horizontal wires (or interconnect structures) and vertical wires (or vias). The interconnect structures 130d are formed on the top and bottom surfaces of the conductive layer 130c. The conductive layer 130c and the interconnect structures 130d may be made of copper, aluminum, nickel, barrier metals (e.g., titanium, tungsten, and tantalum), gold, tin, other suitable conductive materials, or the aforementioned alloys.

[0056] Semiconductor chip 130 also includes a sealant 130e covering a chip substrate 130a, a device layer 130b, and a conductive layer 130c, which protects the semiconductor chip 130 from external environmental influences. Examples of materials used for sealant 130e include epoxy mold compounds (EMC), silicone resins, and polyurethane. Semiconductor chip 140 is located between a portion of interposer 120 and semiconductor chip 130. Semiconductor chip 150 is mounted on another portion of interposer 120. Semiconductor chip 160 is bonded to the top surface of semiconductor chip 140. Semiconductor chip 170 is bonded to semiconductor chip 150. Semiconductor chip 180 is stacked on the top surface of semiconductor chip 130.

[0057] Although device 100 is exemplified as a three-dimensional integrated circuit or a chip-on-a-chip package on a substrate, it should be understood that after reading this document, device 100 can be manufactured using other suitable semiconductor packaging technologies.

[0058] Figure 2 This is a bottom (or top) view of the interconnect structure 200 of an exemplary semiconductor chip 130 according to various embodiments of the present invention. Figure 2 As shown, the exemplary interconnect structure 200 includes a supply voltage (Vdd) interconnect structure, a supply voltage (Vss) interconnect structure, a transmitter (Tx) interconnect structure, and a receiver (Rx) interconnect structure. In this exemplary embodiment, the semiconductor chip 130 further includes a plurality of chip nodes connected to the conductive layer 130c. The chip nodes include a supply voltage (Vdd) node that receives the supply voltage (Vdd) signal, a supply voltage (Vss) node that receives the supply voltage (Vss) signal, a plurality of transmitter (Tx) nodes (each transmitter (Tx) node transmits a corresponding one of a plurality of signals, such as a data signal), and a plurality of receiver (Rx) nodes (each receiver (Rx) node receives a corresponding one of a plurality of signals, such as a data signal).

[0059] Please refer to Figure 2Supply voltage (Vdd) interconnect structures are connected to supply voltage (Vdd) nodes and extend along the x-axis and y-axis. In this exemplary embodiment, the supply voltage (Vdd) interconnect structures are symmetrical with respect to the x-axis and y-axis. For example, the number of supply voltage (Vdd) interconnect structures on one side of the x-axis is the same as the number of supply voltage (Vdd) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other with respect to the x-axis. Similarly, the number of supply voltage (Vdd) interconnect structures on one side of the y-axis is the same as the number of supply voltage (Vdd) interconnect structures on the other side of the y-axis, and their positions are mirror images of each other with respect to the y-axis. In some embodiments, the supply voltage (Vdd) interconnect structures are arranged on both sides of the x-axis and y-axis.

[0060] In an alternative embodiment, the supply voltage (Vdd) interconnect structure is asymmetrical with respect to the y-axis. For example, the number of supply voltage (Vdd) interconnect structures on one side of the y-axis is greater than or less than the number of supply voltage (Vdd) interconnect structures on the other side of the y-axis. As another example, the number of supply voltage (Vdd) interconnect structures on one side of the y-axis is the same as the number of supply voltage (Vdd) interconnect structures on the other side of the y-axis. In this further example, the supply voltage (Vdd) interconnect structures do not form a mirror image with respect to the y-axis.

[0061] Similarly, supply voltage (Vss) interconnect structures are connected to supply voltage (Vss) nodes and arranged on both sides of the x-axis and y-axis. In this exemplary embodiment, the supply voltage (Vss) interconnect structures are symmetrical with respect to the x-axis and y-axis. For example, the number of supply voltage (Vss) interconnect structures on one side of the x-axis is the same as the number of supply voltage (Vss) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other with respect to the x-axis. Similarly, the number of supply voltage (Vss) interconnect structures on one side of the y-axis is the same as the number of supply voltage (Vss) interconnect structures on the other side of the y-axis, and their positions are mirror images of each other with respect to the y-axis.

[0062] In an alternative embodiment, the supply voltage (Vss) interconnect structure is asymmetrical with respect to the y-axis. For example, the number of supply voltage (Vss) interconnect structures on one side of the y-axis is greater than or less than the number of supply voltage (Vss) interconnect structures on the other side of the y-axis. As another example, the number of supply voltage (Vss) interconnect structures on one side of the y-axis is the same as the number of supply voltage (Vss) interconnect structures on the other side of the y-axis. In this further example, the supply voltage (Vss) interconnect structures do not form a mirror image with respect to the y-axis.

[0063] Transmitter (Tx) interconnect structures (e.g., a specific number) are connected to specific transmitter (Tx) nodes and arranged on both sides of the x-axis and y-axis. In this exemplary embodiment, the transmitter (Tx) interconnect structures are symmetrical with respect to the x-axis. For example, the number of transmitter (Tx) interconnect structures on one side of the x-axis is the same as the number of transmitter (Tx) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other with respect to the x-axis.

[0064] Furthermore, such as Figure 2 As shown, the transmitter (Tx) interconnect structure is asymmetrical with respect to the y-axis. For example, the number of transmitter (Tx) interconnect structures on one side of the y-axis is greater than or less than the number of transmitter (Tx) interconnect structures on the other side of the y-axis. As another example, the number of transmitter (Tx) interconnect structures on one side of the y-axis is the same as the number of transmitter (Tx) interconnect structures on the other side of the y-axis. In this other example, the transmitter (Tx) interconnect structures do not form a mirror image with respect to the y-axis.

[0065] Similarly, receiver (Rx) interconnect structures (e.g., a specific number) are connected to specific receiver (Rx) nodes and arranged on both sides of the x-axis and y-axis. In this exemplary embodiment, the receiver (Rx) interconnect structures are symmetrical with respect to the x-axis. For example, the number of receiver (Rx) interconnect structures on one side of the x-axis is the same as the number of receiver (Rx) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other with respect to the x-axis.

[0066] Furthermore, such as Figure 2 As shown, the receiver (Rx) interconnect structure is asymmetrical with respect to the y-axis. For example, the number of receiver (Rx) interconnect structures on one side of the y-axis is greater than or less than the number of receiver (Rx) interconnect structures on the other side of the y-axis. As another example, the number of receiver (Rx) interconnect structures on one side of the y-axis is the same as the number of receiver (Rx) interconnect structures on the other side of the y-axis. In this other example, the receiver (Rx) interconnect structures do not form a mirror image with respect to the y-axis.

[0067] As described above, the semiconductor chip 130 includes interconnect structures 200 on its top and bottom surfaces. The interconnect structures 200 on the top surface of the semiconductor chip 130 are symmetrical about the x-axis, and the interconnect structures 200 on the bottom surface of the semiconductor chip 130 are also symmetrical about the x-axis. Even when the semiconductor chip 130 is rotated 180° about the x-axis, this configuration ensures that the semiconductor chip 130 is correctly bonded to another semiconductor chip (e.g., semiconductor chip 140) or an interposer (e.g., interposer 120).

[0068] Figure 3This is a bottom (or top) view of the interconnect structure 300 of an exemplary semiconductor chip 130 according to various embodiments of the present invention. Figure 3 As shown, the difference between the exemplary interconnect structure 300 and the interconnect structure 200 is that the transmitter (Tx) interconnect structures are symmetrical with respect to the y-axis. For example, the number of transmitter (Tx) interconnect structures on one side of the y-axis is the same as the number of transmitter (Tx) interconnect structures on the other side of the y-axis, and their positions are mirror images of each other with respect to the y-axis.

[0069] Furthermore, such as Figure 3 As shown, the transmitter (Tx) interconnect structure is asymmetrical with respect to the x-axis. For example, the number of transmitter (Tx) interconnect structures on one side of the x-axis is greater than or less than the number of transmitter (Tx) interconnect structures on the other side of the x-axis. As another example, the number of transmitter (Tx) interconnect structures on one side of the x-axis is the same as the number of transmitter (Tx) interconnect structures on the other side of the x-axis. In this other example, the transmitter (Tx) interconnect structures do not form a mirror image with respect to the x-axis.

[0070] Similarly, the receiver (Rx) interconnect structures are symmetrical with respect to the y-axis. For example, the number of receiver (Rx) interconnect structures on one side of the y-axis is the same as the number of receiver (Rx) interconnect structures on the other side of the y-axis, and their positions are mirror images of each other with respect to the y-axis.

[0071] Furthermore, such as Figure 3 As shown, the receiver (Rx) interconnect structure is asymmetrical with respect to the x-axis. For example, the number of receiver (Rx) interconnect structures on one side of the x-axis is greater than or less than the number of receiver (Rx) interconnect structures on the other side of the x-axis. As another example, the number of receiver (Rx) interconnect structures on one side of the x-axis is the same as the number of receiver (Rx) interconnect structures on the other side of the x-axis. In this other example, the receiver (Rx) interconnect structures do not form a mirror image with respect to the x-axis.

[0072] As described above, the semiconductor chip 130 includes interconnect structures 300 on its top and bottom surfaces. The interconnect structures 300 on the top surface of the semiconductor chip 130 are symmetrical about the y-axis, and the interconnect structures 300 on the bottom surface of the semiconductor chip 130 are also symmetrical about the y-axis. Even when the semiconductor chip 130 is rotated 180° about the y-axis, this configuration ensures that the semiconductor chip 130 is correctly bonded to another semiconductor chip (e.g., semiconductor chip 140) or an interposer (e.g., interposer 120).

[0073] Figure 4 This is a bottom (or top) view of the interconnect structure 400 of an exemplary semiconductor chip 130 according to various embodiments of the present invention. Figure 3 As shown, the exemplary interconnect structure 400 differs from interconnect structures 200 and 300 in that the transmitter (Tx) interconnect structures are symmetrical with respect to the x and y axes. For example, the number of transmitter (Tx) interconnect structures on one side of the x-axis is the same as the number of transmitter (Tx) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other with respect to the x-axis. Similarly, the number of transmitter (Tx) interconnect structures on one side of the y-axis is the same as the number of transmitter (Tx) interconnect structures on the other side of the y-axis, and their positions are mirror images of each other with respect to the y-axis.

[0074] The receiver (Rx) interconnect structure is symmetrical with respect to the x and y axes. For example, the number of receiver (Rx) interconnect structures on one side of the x-axis is the same as the number of receiver (Rx) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other with respect to the x-axis. Similarly, the number of receiver (Rx) interconnect structures on one side of the y-axis is the same as the number of receiver (Rx) interconnect structures on the other side of the y-axis, and their positions are mirror images of each other with respect to the y-axis.

[0075] As described above, the semiconductor chip 130 includes interconnect structures 400 on its top and bottom surfaces. The interconnect structures 400 on the top surface of the semiconductor chip 130 are symmetrical with respect to the x and y axes, and the interconnect structures 400 on the bottom surface of the semiconductor chip 130 are also symmetrical with respect to the x and y axes. Even when the semiconductor chip 130 is rotated 180° about the x-axis or y-axis, or rotated 90°, 180°, or 270° about an axis transverse to the x and y axes, this configuration ensures that the semiconductor chip 130 is correctly bonded to another semiconductor chip (e.g., semiconductor chip 140) or an interposer (e.g., interposer 120).

[0076] Figure 5 This is a bottom (or top) view of the interconnect structure 500 of an exemplary semiconductor chip 130 according to various embodiments of the present invention. Figure 5 As shown, the exemplary interconnect structure 500 differs from interconnect structures 200, 300, and 400 in that interconnect structure 500 also includes clock pulse (clk) interconnect structures. The chip node also includes clock pulse nodes for transmitting or receiving clock pulse signals. The clock pulse interconnect structures are connected to the clock pulse nodes and are positioned relative to the y-axis. In this exemplary embodiment, the clock pulse interconnect structures are symmetrical about the x-axis. For example, the number of clock pulse (clk) interconnect structures on one side of the x-axis is the same as the number of clock pulse (clk) interconnect structures on the other side of the x-axis, and their positions are mirror images of each other relative to the x-axis.

[0077] In an alternative embodiment, the interconnect structure 500 further includes a second clock pulse (clk) interconnect structure connected to the clock pulse node and positioned relative to the x-axis. In this alternative embodiment, the second clock pulse (clk) interconnect structure is asymmetrical with respect to the y-axis. For example, the number of second clock pulse (clk) interconnect structures on one side of the y-axis is greater than or less than the number of second clock pulse (clk) interconnect structures on the other side of the y-axis. As another example, the number of second clock pulse (clk) interconnect structures on one side of the y-axis is the same as the number of second clock pulse (clk) interconnect structures on the other side of the y-axis. In this further example, the second clock pulse (clk) interconnect structures do not form a mirror image with respect to the y-axis.

[0078] Because multiple interconnect structures are connected to the clock pulse node, the clock pulse signal is more evenly distributed, reducing or eliminating the time difference (skew) between different points of the device 100 that receive the same clock pulse signal.
