Abstract: Self-aligned gate endcap (SAGE) architectures without fin end gaps, and methods of fabricating self-aligned gate endcap (SAGE) architectures without fin end gaps, are described. In an example, an integrated circuit structure includes a semiconductor fin having a cut along a length of the semiconductor fin. A gate endcap isolation structure has a first portion parallel with the length of the semiconductor fin and is spaced apart from the semiconductor fin. The gate endcap isolation structure also has a second portion in a location of the cut of the semiconductor fin and in contact with the semiconductor fin.

Abstract: An integrated circuit interconnect structure includes a metallization level above a first device level. The metallization level includes an interconnect structure coupled to the device structure, a conductive cap including an alloy of a metal of the interconnect structure and either silicon or germanium on an uppermost surface of the interconnect structure. A second device level above the conductive cap includes a transistor coupled with the conductive cap. The transistor includes a channel layer including a semiconductor material, where at least one sidewall of the conductive cap is co-planar with a sidewall of the channel layer. The transistor further includes a gate on a first portion of the channel layer, where the gate is between a source region and a drain region, where one of the source or the drain region is in contact with the conductive cap.

Abstract: Integrated circuit structures having source or drain structures and germanium N-channels are described. In an example, an integrated circuit structure includes a fin having a lower fin portion and an upper fin portion, the upper fin portion including germanium. A gate stack is over the upper fin portion of the fin. A first source or drain structure includes an epitaxial structure embedded in the fin at a first side of the gate stack. A second source or drain structure includes an epitaxial structure embedded in the fin at a second side of the gate stack. Each epitaxial structure includes a first semiconductor layer in contact with the upper fin portion, and a second semiconductor layer on the first semiconductor layer. The first semiconductor layer comprises silicon, germanium and phosphorous, and the second semiconductor layer comprises silicon and phosphorous.
