Abstract: Transistor structures comprising a gate electrode, or “gate,” that is self-aligned to underlying channel material. A mask material employed for patterning the channel material is further employed to define a cap of mask material having a larger width that protects a portion of gate material during a gate etch. The cap is therefore self-aligned to the channel material so that an amount by which a gate material extends laterally beyond the channel material is ensured to be symmetrical about a centerline of the channel material.

Abstract: Techniques for improved extreme ultraviolet (EUV) patterning using assist features, related transistor structures, integrated circuits, and systems, are disclosed. A number of semiconductor fins and assist features are patterned into a semiconductor substrate using EUV. The assist features increase coverage of absorber material in the EUV mask, thereby reducing bright field defects in the EUV patterning. The semiconductor fins and assist features are buried in fill material and a mask is patterned that exposes the assist features and covers the semiconductor fins. The exposed assist features are partially removed and the protected active fins are ultimately used in transistor devices.

Abstract: An integrated circuit interconnect structure includes a first metallization level including a first metal line having a first sidewall and a second sidewall extending a length in a first direction. A second metal line is adjacent to the first metal line and a dielectric is between the first metal line and the second metal line. A second metallization level is above the first metallization level where the second metallization level includes a third metal line extending a length in a second direction orthogonal to the first direction. The third metal line extends over the first metal line and the second metal line but not beyond the first sidewall. A conductive via is between the first metal line and the third metal line where the conductive via does not extend beyond the first sidewall or beyond the second sidewall.

Abstract: Integrated circuit (IC) devices include transistors with gate, source and drain contact metallization, some of which are jumpered together by a metallization that is recessed below a height of other metallization that is not jumpered. The jumper metallization may provide a local interconnect between terminals of one transistor or adjacent transistors, for example between a gate of one transistor and a source/drain of another transistor. The jumper metallization may not induce the same pitch constraints faced by interconnect line metallization levels employed for more general interconnection. In some examples, a static random-access memory (SRAM) bit-cell includes a jumper metallization joining two transistors of the cell to reduce cell height for a given feature patterning capability.

Abstract: Metal spacer-based approaches for fabricating conductive lines/interconnects are described. In an example, an integrated circuit structure includes a substrate. A first spacer pattern is on the substrate, the first spacer pattern comprising a first plurality of dielectric spacers and a first plurality of metal spacers formed along sidewalls of the first plurality of dielectric spacers, wherein the first plurality of dielectric spacers have a first width (W1). A second spacer pattern is on the substrate, where the second spacer pattern interleaved with the first spacer pattern, the second spacer pattern comprising a second plurality of dielectric spacers having a second width (W2) formed on exposed sidewalls of the first plurality of metal spacers, and a second plurality of metal spacers formed on exposed sidewalls of the second plurality of dielectric spacers.

Abstract: Back-side transistor contacts that wrap around a portion of source and/or drain semiconductor bodies, related transistor structures, integrated circuits, systems, and methods of fabrication are disclosed. Such back-side transistor contacts are coupled to a top and a side of the source and/or drain semiconductor and extend to back-side interconnects. Coupling to top and side surfaces of the source and/or drain semiconductor reduces contact resistance and extending the metallization along the side reduces transistor cell size for improve device density.
