摘要:
A MOS transistor process includes the following steps. A gate structure is formed on a substrate. A source/drain is formed in the substrate beside the gate structure. After the source/drain is formed, (1) at least a recess is formed in the substrate beside the gate structure. An epitaxial structure is formed in the recess. (2) A cleaning process may be performed to clean the surface of the substrate beside the gate structure. An epitaxial structure is formed in the substrate beside the gate structure.
