Method of salicide formation with a double gate silicide
摘要:
A method of forming a self-aligned silicide (salicide) with a double gate silicide. The method improves transistor speed by lowering the leakage current in the source and drain areas and lowering the polysilicon sheet resistance of the gate. As a result of one embodiment of the present method, a silicide is formed over the gate area which is advantageously thicker than silicide formations over the source and drain areas.
