Abstract:
A semiconductor device, comprising:conductive transfer gates comprising conductive parts; contact plugs adjacent to said conductive transfer gates, each contact plug and each conductive transfer gate having a respective upper surface, wherein the upper surfaces of the contact plugs and the upper surfaces of the conductive transfer gates are substantially coplanar; said each conductive transfer gate having a gate insulating film, a gate electrode layer, and side walls for covering sides of said gate insulating film and said gate electrode layer; said contact plugs adjacent to said gate electrode layer, said side wall interposed therebetween: a first interlayer insulating film having a surface which defines the same surface as the upper surfaces of said conductive transfer gates and said contact plugs; a second interlayer insulating film Formed on said first interlayer insulating film; and diameter-reduced contact plugs which are smaller than said contact plugs and extend through said second interlayer insulating film to conduct to said contact plugs, respectively.
