Abstract:
Disclosed are embodiments of a semiconductor structure that includes a vertical field effect transistor (VFET). The VFET has a fin-shaped body that includes a semiconductor fin and an isolation fin. The semiconductor fin extends vertically between lower and upper source/drain regions. The isolation fin is adjacent to and in end-to-end alignment with the semiconductor fin. The VFET gate has a main section that wraps around an outer end and opposing sidewalls of the semiconductor fin and an extension section that extends from the main section along at least the opposing sidewalls of a lower portion the isolation fin and, optionally, around an outer end of that lower portion. A gate contact lands on the isolation fin and extends along the opposing sidewalls and, optionally, the outer end of the isolation fin down to the extension section. Also disclosed are method embodiments for forming these structures.

Claim (Index 4):
The method of  claim 3 , the replacing comprising:\n forming a fin cut opening in the end portion of the semiconductor fin immediately adjacent to the isolation region, the fin cut opening extending through the end portion and into the substrate; and filling the fin cut opening with a second isolation material that is different from the first isolation material to form the isolation fin.
