Patent ID: 8847232

Claim:
A transistor comprising: a substrate; a first electrically conductive material layer positioned on the substrate, the first electrically conductive material layer having a thickness; a second electrically conductive material layer in contact with and positioned on the first electrically conductive material layer, the second electrically conductive material layer overhanging and extending beyond the first electrically conductive material layer, the second electrically conductive material layer including a reentrant profile in which a first portion of the second electrically conductive material layer overhangs a second portion of the second electrically conductive material layer; an electrically insulating material layer conformally positioned over the second electrically conductive material layer, the first electrically conductive material layer, and at least a portion of the substrate, the electrically insulating material layer having a thickness wherein the thickness of the first electrically conductive layer is twice the thickness of the electrically insulating material layer; and a semiconductor material layer that conforms to and is in contact with the electrically insulating material layer.
