Abstract:
A semiconductor device includes an active pillar on a substrate. A first source/drain region is disposed at a top end of the active pillar and has a greater width than the active pillar. A first insulating layer is disposed on a sidewall of the active pillar and a second insulating layer is disposed on at least a bottom surface of the first source/drain region. A gate electrode is disposed on the first insulating layer and the second insulating layer. A second source/drain region is disposed in the substrate at a bottom end of the active pillar. Methods of fabrication are also described.

Claim (Index 30):
A method of fabricating a semiconductor device, the method comprising:\n forming an active pillar protruding from a surface of a semiconductor substrate; forming a first source/drain region in the semiconductor substrate at a bottom end of the active pillar; forming a first insulating layer covering a lower portion of the active pillar and exposing an upper portion of the active pillar; forming a second source/drain region on the exposed upper portion of the active pillar, the second source/drain region having a greater width than the active pillar and spaced apart from the first insulating layer; forming a spacer on a sidewall and a bottom surface of the second source/drain region to be in contact with an upper sidewall of the active pillar; removing the first insulating layer to expose a bottom surface of the spacer and a portion of a sidewall of the active pillar; and forming a gate electrode on the bottom surface of the spacer and on the sidewall of the active pillar.
