Abstract:
Disclosed is a semiconductor structure that includes a vertical field effect transistor (VFET) with a U-shaped semiconductor body. The semiconductor structure can be a standard VFET or a feedback VFET. In either case, the VFET includes a lower source/drain region, a semiconductor body on the lower source/drain region, and an upper source/drain region on the top of the semiconductor body. Rather than having an elongated fin shape, the semiconductor body folds back on itself in the Z direction so as to be essentially U-shaped (as viewed from above). Using a U-shaped semiconductor body reduces the dimension of the VFET in the Z direction without reducing the end-to-end length of the semiconductor body. Thus, VFET cell height can be reduced without reducing device drive current or violating critical design rules. Also disclosed is a method of forming a semiconductor structure that includes such a VFET with a U-shaped semiconductor body.

Claim (Index 26):
