Abstract
A thin-film transistor and SRAM memory cell include thin-film source and drain regions (12, 14) separated by an opening (22) and overlying and insulating layer (11). A thin-film channel layer (16) overlies the thin-film source and drain regions (12, 14) and a portion of the insulating layer (11) exposed by the opening (22). A thin-film gate electrode (20) is positioned in the opening (22) and defines a thin-film channel region (24) in the thin-film channel layer (16). The thin-film gate electrode (20) is separated from the thin-film channel region (24) by a gate dielectric layer (18). The thin-film channel region (24) extends along vertical wall surfaces (26, 28) of the thin-film source and drain regions (12, 14) providing an extended channel length for the thin-film transistor.
