A semiconductor device according to one embodiment includes: a semiconductor substrate comprising an element isolation region; two gate electrodes formed in substantially parallel on the semiconductor substrate via respective gate insulating films; two channel regions each formed in regions of the semiconductor substrate under the two gate electrodes; a source/drain region formed in a region of the semiconductor substrate sandwiching the two channel regions; a first stress film formed so as to cover the semiconductor substrate and the two gate electrodes; and a second stress film formed in at least a portion of a void, the void being formed in a region between the two gate electrodes.
