Abstract

A semiconductor device according to the present invention has an n-type MIS transistor. The n-type MIS transistor has a first active region surrounded by a device isolation region in a semiconductor substrate, a first gate insulating film having a first high-dielectric-constant insulating film containing a first metal for adjustment, and a first electrode formed on the first gate insulating film. A protrusion amount of one end of the first high-dielectric-constant insulating film on the first device isolation part is smaller than a protrusion amount of an end of the first gate electrode above the first device isolation part.
