Claim Text:
1. A method of making a semiconductor device, comprising: forming a sacrificial layer on a semiconductor substrate; forming a gate electrode on the sacrificial layer, wherein the gate electrode is composed of a single crystalline semiconductor material; removing a portion of the sacrificial layer over regions adjacent to the gate electrode that will become a source region and a drain region: implanting/diffusing ions into the source region and the drain region adjacent to the gate electrode while implanting/diffusing ions into the gate electrode, wherein the ions implanted into the gate electrode are the opposite conductivity type to the conductivity type of the semiconductor substrate; and then removing the remainder of the sacrificial layer, wherein removal of the sacrificial layer creates an air layer between the gate electrode and the semiconductor substrate, wherein the gate electrode is vertically movable within the air layer.
