Semiconductor device and method of manufacturing semiconductor device

摘要

A semiconductor device including an NMOS region and a PMOS region in the same substrate, wherein the semiconductor device includes a strained Si layer which is provided on the substrate in the NMOS region and in which the surface has a plane orientation different from that of the substrate, and a strained SiGe layer which is provided on the substrate in the PMOS region and which is composed of a stained layer having the same plane orientation as that of the surface of the substrate; and a method of manufacturing the same.
