Abstract:
A method of forming a semiconductor structure includes forming at least one fin disposed over a substrate, wherein sidewalls of the at least one fin includes a first portion proximate a top surface of the substrate having a tapered profile and a second portion disposed above the first portion. The method also includes forming a bottom source/drain region surrounding at least part of the first portion of the sidewalls of the at least one fin having the tapered profile and forming a bottom spacer disposed over a top surface of the bottom source/drain region surrounding at least part of the second portion of the sidewalls of the at least one fin. The at least one fin provides a channel for a vertical field-effect transistor.

Claim (Index 5):
The method of  claim 1 , further comprising:\n depositing a spacer over the oxide, the hard mask layer and exposed sidewalls of the at least one fin; and etching the spacer to remove portions of the spacer disposed on the top surface of the hard mask layer and the oxide and to leave portions of the spacer disposed on sidewalls of the hard mask layer and on the second portion of the sidewalls of the at least one fin.
