<p>A thin body MOSFET with conducting surface channel extensions and gate-controlled channel sidewalls is described. One embodiment is a MOSFET comprising a semiconductor substrate; a channel layer disposed on a top surface of the substrate; a gate dielectric layer interposed between a gate electrode and the channel layer; and dielectric extension layers disposed on top of the channel layer and interposed between the gate electrode and Ohmic contacts. The gate dielectric layer comprises a first material, the first material forming an interface of low defectivity with the channel layer. In contrast, the dielectric extensions comprise a second material different than the first material, the second material forming a conducting surface channel with the channel layer.</p> |
