Abstract:
A MOSFET comprising:a layer of semiconductor material; a gate formed over the layer of semiconductor material, the gate including a gate electrode and a gate dielectric formed from a high-K material, the gate dielectric separating the gate electrode and the layer of semiconductor material; a source and a drain each formed by selective in-situ doped epitaxy and located adjacent opposite sides of the gate so as to define a body region from the layer of semiconductor material between the source and the drain and under the gate, wherein an upper portion of each of the source and the drain adjacent the body region extend higher than the gate dielectric and a lower portion of each of the source and the drain form a junction with the body region; a liner disposed adjacent each sidewall of the gate electrode, said liners separating the gate electrode from the upper portion of the source and the drain; and a sidewall spacer disposed adjacent each of the liners, the sidewall spacers disposed on the upper portions of the source and drain and defining the lateral placement of a source contact and a drain contact.
