Abstract:
A semiconductor device comprising:a semiconductor substrate of a first conductivity type having a main surface;first and second impurity regions of a second conductivity type formed on the main surface of said semiconductor substrate with a predetermined space defining a channel region between each other;a first floating gate electrode formed on said channel region with a first gate insulating film therebetween and having an end overlapping with said first impurity region;a control gate electrode formed on an upper surface of said first floating gate electrode with a first interlayer insulating film therebetween; anda second floating gate electrode formed on an upper surface and a side surface of said control gate electrode with a second interlayer insulating film therebetween and formed on said channel region with a second gate insulating film therebetween to have an end overlapping with said second impurity region.
