Abstract
A semiconductor device is formed by patterning a semiconductor layer to create a vertical active region and a horizontal active region, wherein the horizontal active region is adjacent the vertical active region. The semiconductor layer overlies an insulating layer. A spacer is formed adjacent the vertical active region and over a portion of the horizontal active region. At least a portion of the horizontal active region is oxidized to form an isolation region. The spacer is removed. A gate dielectric is formed over the vertical active region after removing the spacer. A gate electrode is formed over the gate dielectric. However, forming the spacer is optional.
