Abstract
A semiconductor device includes: a transistor having source and drain regions; first and second contact electrodes embedded in a first interlayer insulating film, and electrically connected to the source region and the drain region, respectively; a third electrode embedded in a second interlayer insulating film positioned in an upper layer of the first interlayer insulating film, and electrically connected to the first contact electrode; a wiring pattern embedded in a third interlayer insulating film positioned in an upper layer of the second interlayer insulating film, and electrically connected to the third contact electrode; and a fourth contact electrode embedded in at least the second and third interlayer insulating films, and electrically connected to the second contact electrode, wherein side surfaces of the wiring pattern along an extending direction of the wiring pattern coincide with side surfaces of the third contact electrode along an extending direction of the wiring pattern.
