Abstract

Abstract A semiconductor device comprises, at least, an insulative layer; a semiconductor layer provided in contact with the insulative layer; first and second electrodes provided in contact with the semiconductor layer; and a third electrode provided through the insulative layer. The semiconductor layer has a crystallite layer whose average grain diameter lies within a range from 50 to 350 Å and an amorphous layer.
