    摘要: The present disclosure provides a thermo-mechanically reliable copper TSV and a technique to form such TSV during BEOL processing. The TSV constitutes an annular trench which extends through the semiconductor substrate. The substrate defines the inner and outer sidewalls of the trench, which sidewalls are separated by a distance within the range of 5 to 10 microns. A conductive path comprising copper or a copper alloy extends within said trench from an upper surface of said first dielectric layer through said substrate. The substrate thickness can be 60 microns or less. A dielectric layer having interconnect metallization conductively connected to the conductive path is formed directly over said annular trench.

    摘要: A tool that allows three dimensional chip circuit designs to be checked subsequent to 3D design layer mirroring. The 3D chip design is converted to a corresponding 2D chip design by mirroring one or more design layers from the mirrored side of a 3D design and merging those design layers with unmirrored design layers from the unmirrored side of a 3D design. The converted circuit design can be processed by standard verification checks. The tool may also receive design layers corresponding to an integrated circuit that will pass through multiple semiconductor chips. Each design cell is examined to determine if it corresponds to a mirrored or unmirrored side of its respective semiconductor chip. If the respective design cell corresponds to the mirrored side, the design cell is mirrored. All mirrored cells are then merged with the unmirrored design cells in the correct order. The merged design is processed by standard verification checks. The tool also has the capability to create terminal metal abstracts for two adjoining chips. One of the abstracts is mirrored and then merged with the other for connectivity and alignment checking.

    摘要: A TSV can be formed having a top section via formed through the top substrate surface and a bottom section via formed through the bottom substrate surface. The top section cross section can have a minimum cross section corresponding to design rules, and the top section depth can correspond to a workable aspect ratio. The top section via can be filled or plugged so that top side processing can be continued. The bottom section via can have a larger cross section for ease of forming a conductive path therethrough. The bottom section via extends from the back side to the bottom of the top section via and is formed after the substrate has been thinned. The TSV is can be completed by forming a conductive path after removing sacrificial fill materials from the joined top and bottom section vias.

    摘要: A through-silicon via (TSV) structure forming a unique coaxial or triaxial interconnect within the silicon substrate. The TSV structure is provided with two or more independent electrical conductors insulated from another and from the substrate. The electrical conductors can be connected to different voltages or ground, making it possible to operate the TSV structure as a coaxial or triaxial device. Multiple layers using various insulator materials can be used as insulator, wherein the layers are selected based on dielectric properties, fill properties, interfacial adhesion, CTE match, and the like. The TSV structure overcomes defects in the outer insulation layer that may lead to leakage. A method of fabricating such a TSV structure is also described.
