Abstract
In a semiconductor device, a first p-type MIS transistor includes: a first gate insulating film formed on a first active region; a first gate electrode formed on the first gate insulating film; a first side-wall insulating film; a first p-type source/drain region; a first contact liner film formed over the first active region; a first interlayer insulating film formed on the first contact liner film; and a first contact plug formed to reach the top surface of the first source/drain region. The first contact liner film has a slit extending, around a corner at which the side surface of the first side-wall insulating film intersects the top surface of the first active region, from the top surface of the first contact liner film toward the corner.
