Abstract
In a method of fabricating a semiconductor device on a substrate having a pillar pattern, a gate electrode is formed on the pillar pattern without etching the latter. A conductive pattern is filled between adjacent pillar patterns, a spacer is formed above the conductive pattern and surrounding sidewalls of each pillar pattern, and the gate electrode is formed by etching the conductive pattern using the spacer as an etch barrier.
