Abstract:
An integrated circuit field effect transistor comprising:an integrated circuit substrate;spaced apart source/drain regions in the integrated circuit substrate, at a face thereof;an insulating film on the face, between the spaced apart source/drain regions;a gate electrode on a portion of the insulating film, between the spaced apart source/drain regions such that the insulating film extends from beneath the gate electrode to outside the gate electrode, the gate electrode comprising:a first conductive layer comprising titanium nitride on the insulating film; anda second conductive layer on the first conductive layer, which is wider than the first conductive layer and which extends beyond the first conductive layer towards the source/drain regions;wherein the insulating film is thicker beneath the first conductive layer compared to outside the first conductive layer.
