Abstract

Semiconductor structures and methods for forming a semiconductor structure are provided. An active semiconductor region is disposed in a substrate. A gate is formed over the substrate. Source and drain regions of a transistor are formed in the active semiconductor region on opposite sides of the gate. The drain region has a first width, and the source region has a second width that is not equal to the first width.
