Abstract:
A semiconductor device having six transistors including first and second load transistors, first and second driver transistors and first and second access transistors, and having a lead connection structure wherein at least two lead layers are electrically interconnected via contact holes, said semiconductor device comprising:a semiconductor substrate having a principal plane;a first and a second impurity region having opposite conductivities formed on said principal plane of said semiconductor substrate;a first insulating film which is formed on said first and second impurity regions and which has a first through hole reaching a surface of said first impurity region;first lead formed on said first insulating film and connected electrically via said first through hole to said first impurity region to form a drain region outgoing lead for two of said six transistors;a second insulating film formed so as to cover said first lead; anda second lead formed on said second insulating film, said second lead being electrically connected to said second impurity region via a second through hole penetrating said first insulating film, said first lead and said second insulating film to form a drain region outgoing lead for two of said six transistors;wherein interconnection of said first and said second impurity regions is accomplished by connecting said first lead, said second lead and said second impurity region inside said second through hole; andwherein one of said first lead and said second lead is constituted by a polycrystal silicon film.
