Abstract

A method of manufacturing an integrated circuit with a strained semiconductor channel region. The method can provide a double gate structure. The gate structure can be provided in and above a trench. The trench can be formed in a compound semiconductor material such as a silicon-germanium material. The strained semiconductor can increase the charge mobility associated with the transistor. A silicon-on-insulator substrate can be used.
