Abstract:
1. A manufacturing method of a semiconductor device comprising: forming an n-channel metal-oxide-semiconductor transistor in a first region on a surface of a semiconductor substrate and a p-channel metal-oxide-semiconductor transistor in a second region on the surface of the semiconductor substrate; forming a contracting film in the first region, in the second region, and in a third region and a fourth region on the surface of the semiconductor substrate; and performing an ion implantation into the contracting film to relax a stress of the contracting film in the first region, the second region, and the fourth region, and leave a stress of the contracting film in the third region, wherein the first region is in contact with the third region in a first direction, the second region is in contact with the third region in a second direction perpendicular to the first direction, the fourth region is in contact with the first region in the second direction and is in contact with the second region in the first direction, a channel width direction of the n-channel metal-oxide-semiconductor transistor is parallel to the second direction, a channel width direction of the p-channel metal-oxide-semiconductor transistor is parallel to the second direction, and the first direction and the second direction are perpendicular to a normal line to the surface of the semiconductor substrate.
