Patent ID: 8633068

Claim:
A method of actuating a semiconductor device comprising: providing a transistor including: a substrate; a first electrically conductive material layer stack positioned on the substrate, the first electrically conductive material layer stack including a reentrant profile; an electrically insulating material layer that conforms to the reentrant profile of the first electrically conductive material layer stack, and is in contact with at least a portion of the substrate; a semiconductor material layer that conforms to the reentrant profile, and is in contact with the electrically insulating material layer; a second electrically conductive material layer, a source electrode including a first discrete portion of the second electrically conductive material layer, the source electrode being in contact with a first portion of the semiconductor material layer and adjacent to the first electrically conductive material layer stack, a drain electrode including a second discrete portion of the second electrically conductive material layer, the drain electrode being in contact with a second portion of the semiconductor material layer and adjacent to the first electrically conductive material layer stack; a third electrically conductive material layer in contact with a third portion of the semiconductor material layer, the third electrically conductive material layer being positioned on the third portion of the semiconductor material layer located over the first electrically conductive material layer stack but not in electrical contact with the first electrically conductive material layer stack, the third electrically conductive material layer being physically and electrically separated from the source electrode and the drain electrode; applying a voltage between the source electrode and the drain electrode; and applying a voltage to the first electrically conductive material layer stack to modulate a resistance between the source electrode and the drain electrode.
