Patent ID: 7164175

Claim:
A semiconductor device comprising: a semiconductor substrate; a plurality of insulating films provided on a surface of the semiconductor substrate so as to be perpendicular to the surface; a first and second semiconductor films each having a thickness thinner than a gate length and provided on a first and second side surface of each of said plurality of insulating films; a plurality of gate electrodes each provided so as to interpose the corresponding first and second semiconductor films and the corresponding insulating films in between from upper side; a first wiring which selectively connects the plurality of gate electrodes with one another; a second wiring which selectively connects the plurality of gate electrodes with the first and second semiconductor films and the first and second semiconductor films with one another; and a plurality of wiring contacts which are selectively connected to the plurality of gate electrodes and the first and second semiconductor films; wherein a 6-transistor-structure SRAM (Static Random Access Memory) cell is configured in such a manner that, said plurality of insulating films include at least a first, second, third, and fourth insulating films, and the first wiring connects a first and fourth gate electrodes provided on the corresponding first and fourth insulating films with each other, the second wiring connects a second gate electrode provided on the second insulating film and the first semiconductor film provided on a first side surface of the fourth insulating film with each other and a first and second semiconductor film provided on a first and second side surface of the third insulating film with each other, and the plurality of wiring contacts are connected to the first and fourth gate electrodes provided on the first and fourth insulating films, the second semi-conductor film provided on the second side surface of the first insulating film, the first and second semiconductor films provided on the first and second side surfaces of the second insulating film, the first and second semiconductor films provided on the first and second side surfaces of the third insulating film, and the first semiconductor film provided on the first side surface of the fourth insulating film.
