Abstract:
A field effect transistor structure comprising:(A) a substrate; (B) a source electrode comprising a lower conductive oxide disposed atop a first area of said substrate and an upper conductive oxide disposed atop said lower conducting oxide; (C) a drain electrode laterally separated from said source electrode, wherein said drain electrode comprises said lower conductive oxide disposed atop a second area of said substrate and said upper conductive oxide disposed atop said lower conductive oxide; (D) a channel oxide layer atop an exposed region of said substrate and atop said source and drain electrodes, wherein said exposed region lies between and laterally separates said source electrode and said drain electrode, wherein said channel oxide layer covering said exposed region forms a channel in said device; (E) a gate oxide material covering said channel oxide layer; (F) a first and a second filled contact opening, each extending, respectively, in depth through said gate oxide material and said channel oxide layer to said upper conductive oxide of said source and drain electrode, and each said filled contact opening being filled with a conductive metal; and (G) a gate electrode disposed atop said gate oxide material, wherein said gate electrode is laterally positioned between said first and second filled contact openings.
