Patent ID: 8847226

Claim:
A transistor comprising: a substrate; a first electrically conductive material layer positioned on the substrate; a second electrically conductive material layer in contact with and positioned on the first electrically conductive material layer, the second electrically conductive material layer itself including a first 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, the first electrically conductive material layer extending in opposite directions, the first electrically conductive material layer being sized and positioned to end in both directions before the second electrically conductive material layer ends such that the second electrically conductive material layer defines a second reentrant profile relative to the first electrically conductive material layer in which the second electrically conductive material layer overhangs the first electrically conductive material layer, wherein the first reentrant profile is different from the second reentrant profile, 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; and a semiconductor material layer that conforms to and is in contact with the electrically insulating material layer.
