    • PROBLEM TO BE SOLVED: To provide a semiconductor device and a method for manufacturing thereof, which is equipped with a protective insulating film which is little in substrate oxidation, and does not cause the drive power reduction of a PMOS. SOLUTION: A CMOS includes an NMISFET having a first protective insulating film 5 covering the surface of an N-type source-drain region and the periphery of a first gate electrode, and a PMISFET having a second protective insulating film 6 covering a P-type source-drain region 8 formed in both sides of a second gate electrode and the periphery of the second gate electrode, wherein the first protective insulating film 5 consists of one layer or more, the one layer is a silicon nitride film or an silicon oxynitride film, a portion contacting a semiconductor substrate among the second protective insulating film 6 is an silicon oxide film, and wherein the distance from the silicon substrate under the second protective insulating film 6 to the silicon nitride film or the silicon oxynitride film is longer than the distance from the silicon substrate under the first protective insulating film 5 to the silicon nitride film or the silicon oxynitride film.
