    摘要: A method for imparting stress to the channel region of a transistor is provided. In accordance with the method, a semiconductor layer (307) is provided which has a dielectric layer (305) disposed beneath it. A trench (319) is created which extends through the semiconductor layer and into the dielectric layer, and the trench is backfilled with a stressor material (320), thereby forming a trench isolation structure. A channel region (326) is defined in the semiconductor layer adjacent to the trench isolation structure.
