Abstract: Described herein are apparatuses, methods, and systems associated with a deep trench via in a three-dimensional (3D) integrated circuit (IC). The 3D IC may include a logic layer having an array of logic transistors. The 3D IC may further include one or more front-side interconnects on a front side of the 3D IC and one or more back-side interconnects on a back side of the 3D IC. The deep trench may be in the logic layer to conductively couple a front-side interconnect to a back-side interconnect. The deep trench via may be formed in a diffusion region or gate region of a dummy transistor in the logic layer. Other embodiments may be described and claimed.

Abstract: Integrated circuit structures having front side signal lines and backside power delivery are described. In an example, an integrated circuit structure includes a plurality of gate lines extending over a plurality of semiconductor nanowire stack or fin channel structures within a cell boundary. A plurality of trench contacts is extending over a plurality of source or drain structures within the cell boundary, individual ones of the plurality of trench contacts alternating with individual ones of the plurality of gate lines. A first signal line, a second signal line, a third signal line, and a fourth signal line are over the plurality of gate lines and the plurality of trench contacts within the cell boundary. A backside power delivery line is coupled to one of the plurality of trench contacts within the cell boundary.

Abstract: An integrated circuit includes a first device having a first source or drain region, and a second device having a second source or drain region that is laterally adjacent to the first source or drain region. A conductive source or drain contact includes (i) a lower portion in contact with the first source or drain region, and extending above the first source or drain region, and (ii) an upper portion extending laterally from above the lower portion to above the second source or drain region. A dielectric material is between at least a section of the upper portion of the conductive source or drain contact and the second source or drain region. In an example, each of the first and second devices is a gate-all-around (GAA) device having one or more nanoribbons, nanowires, or nanosheets as channel regions, or is a finFet structure having a fin-based channel region.

Abstract: An integrated circuit includes a first device and a laterally adjacent second device. The first device includes a first body including semiconductor material extending from a first source region to a first drain region, and a first gate structure on the first body. The second device includes a second body including semiconductor material extending from a second source region to a second drain region, and a second gate structure on the second body. A gate cut including dielectric material is between and laterally separates the first gate structure and the second gate structure. The first body is separated laterally from the gate cut by a first distance, and the second body is separated laterally from the gate cut by a second distance. In an example, the first and second distances differ by at least 2 nanometers. In an example, the first and second devices are fin-based devices or gate-all-around devices.
