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 apparatus is described. The apparatus includes a FINFET device having a channel. The channel is composed of a first semiconductor material that is epitaxially grown on a subfin structure beneath the channel. The subfin structure is composed of a second semiconductor material that is different than the first semiconductor material. The subfin structure is epitaxially grown on a substrate composed of a third semiconductor material that is different than the first and second semiconductor materials. The subfin structure has a doped region to substantially impede leakage currents between the channel and the substrate.
