Patent ID: 8331185

Claim:
A semiconductor device comprising: (a) a semiconductor substrate, (b) an internal circuitry having a first transistor element formed over the semiconductor substrate, (c) at least one fuse program circuit having a second transistor element formed over the semiconductor substrate, the fuse program circuit including a fuse element, and (d) a plurality of metal interconnection layers formed over the first transistor element and the second transistor element; wherein the fuse element is formed of the metal interconnection layers and includes copper material, wherein the second transistor element connected in series to the fuse element is formed for selectively passing a current for blowing the fuse element, wherein the second transistor element includes a plurality of unit transistors connected in parallel and arranged in a first direction in plan view, wherein the unit transistors respectively have gate electrodes, source regions and drain regions extending in a second direction perpendicular to the first direction in plan view, wherein each of the source regions and each of the drain regions are arranged alternately to each other with a space between, wherein each of the gate electrodes is arranged between the source regions and the drain regions, wherein a first film material of a first gate insulation film of the first transistor is the same as a second film material of a second gate insulation film of each of the unit transistors, and wherein a first film thickness of the first gate insulation film is the same as a second film thickness of the second gate insulation film.
