Abstract
A semiconductor device including an isolation insulating film having a first thickness that is located between a drain region and a source region; a gate electrode formed over a region located between the isolation insulating film and the source region and that includes a part serving as a channel; an interlayer insulating film formed so as to cover the gate electrode; and a contact plug formed to reach the inside of the isolation insulating film while penetrating the interlayer insulating film, wherein the contact plug includes a buried part that is formed from the surface of the isolation insulating film up to a depth corresponding to a second thickness thinner than the first thickness.
