Abstract: Multigate devices and fabrication methods that mitigate the layout effects are described. In conventional processes to fabricate multigate semiconductor devices such as FinFET devices, long isolation cut masks may be used. This can lead to undesirable layout effects. To mitigate or eliminate the layout effect, fabrication methods are proposed in which the interlayer dielectric (ILD) layer remains intact at the gate cut location during the fabrication process.

Abstract: Nanowire channel structures of continuously stacked nanowires for complementary metal oxide semiconductor (CMOS) devices are disclosed. In one aspect, an exemplary CMOS device includes a nanowire channel structure that includes a plurality of continuously stacked nanowires. Vertically adjacent nanowires are connected at narrow top and bottom end portions of each nanowire. Thus, the nanowire channel structure comprises a plurality of narrow portions that are narrower than a corresponding plurality of central portions. A wrap-around gate material is disposed around the nanowire channel structure, including the plurality of narrow portions, without entirely wrapping around any nanowire therein. The exemplary CMOS device provides, for example, a larger effective channel width and better gate control than a conventional fin field-effect transistor (FET) (FinFET) of a similar footprint. The exemplary CMOS device further provides, for example, a shorter nanowire channel structure than a conventional nanowire FET.

Abstract: Cell circuits having a diffusion break with avoided or reduced adjacent semiconductor channel strain relaxation and related methods are disclosed. In one aspect, a cell circuit includes a substrate of semiconductor material and a semiconductor channel structure(s) of a second semiconductor material disposed on the substrate. The semiconductor material applies a stress to the formed semiconductor channel structure(s) to induce a strain in the semiconductor channel structure(s) for increasing carrier mobility. A diffusion break comprising a dielectric material extends through a surrounding structure of an interlayer dielectric, and the semiconductor channel structure(s) and at least a portion of the substrate. The relaxation of strain in areas of the semiconductor channel structure(s) adjacent to the diffusion break is reduced or avoided, because the semiconductor channel structure(s) is constrained by the surrounding structure.

Abstract: Systems and methods for dummy gate tie-offs in a self-aligned gate contact (SAGC) cell are disclosed. In particular, exemplary aspects contemplate a two-part etching process to remove hardmasks formed from different materials from adjacent elements. A metal fill material may then be used to tie off the adjacent elements. The use of the two-part etching process allows SAGC techniques to be used for a first portion of a cell while still providing a technique to allow a tie-off in a second portion of the cell. The tie-off may be used with a dummy gate to provide isolation between cells.
