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 40):
The method of  claim 38 , further comprising:\n forming a first insulating layer covering a lower portion of the active pillar and exposing an upper portion of the active pillar before forming the second source/drain region; and removing the first insulating layer to expose a bottom surface of the spacer and a portion of a sidewall of the active pillar after forming the spacer.
