Abstract:
Disclosed is a method of forming a vertical pillar-type field effect transistor (FET). One or more semiconductor pillars are formed by epitaxial deposition in one or more openings, respectively, that extend through a first dielectric layer and that have high aspect ratios in two directions. The first dielectric layer is etched back and the following components are formed laterally surrounding the semiconductor pillar(s): a first source/drain region above and adjacent to the first dielectric layer, a second dielectric layer on the first source/drain region, a gate on the second dielectric layer and a gate cap on the gate. The gate cap extends over the top surface(s) of the semiconductor pillar(s). A recess is formed in the gate cap to expose at least the top surface(s) of the semiconductor pillar(s) and a second source/drain region is formed within the recess. Also disclosed is the vertical pillar-type FET structure.

Claim (Index 1):
A field effect transistor comprising:\n a substrate; at least one semiconductor pillar having a bottom surface immediately adjacent to the substrate and a top surface opposite the bottom surface; a first dielectric layer above and immediately adjacent to the substrate and laterally surrounding a lower portion of the semiconductor pillar; above the first dielectric layer and laterally surrounding the semiconductor pillar, a first source/drain region immediately adjacent to the first dielectric layer, a second dielectric layer on the first source/drain region, a gate on the second dielectric layer, and a gate cap on the gate, the gate cap having a recess that exposes at least the top surface of the semiconductor pillar and the recess having a bottom that is above and physically separated from a top of the gate; and a second source/drain region within the recess.
