Abstract:
An insulated gate transistor comprising:source regions;drain regions;channel regions provided between said source and drain regions;a gate electrode, said gate electrode having at least two opposing portions which face each other; anda gate insulative film provided between said channel regions and said gate electrode, said gate insulative film also having at least two opposing portions which face each other,wherein said transistor has a semiconductor region which is provided so as to be in contact with said channel regions, said semiconductor region has the same conductivity type as said channel regions and has an impurity concentration higher than that of said channel regions, and said semiconductor region is maintained at a predetermined potential during operation of the transistor, wherein at least a portion of said semiconductor region is disposed between said opposing portions of said gate electrode and between said opposing portions of said gate insulative film, and wherein the portion of semiconductor region extends between the opposing portions of said gate insulative film and is in contact with each of the opposing portions of said rate insulative film.
