Abstract

A vertical transistor includes two portions of a gate conductor that extend within a layer of insulator. An opening extending through the later of insulator includes source, channel and drain regions form by epitaxy operations. A thickness of the portions of the gate conductor decreases in the vicinity of the channel region.
