Abstract

A method of manufacturing an integrated circuit with a channel region containing germanium. The method can provide a double planar gate structure. The gate structure can be provided over lateral sidewalls of channel region. The semiconductor material containing germanium can increase the charge mobility associated with the transistor. An epitaxy process can form the channel region. A silicon-on-insulator can be used.
