The extensions lie beneath the gate in contact with the gate dielectric. The material of the gate dielectric and the amount of its protrusion beyond the gate electrode are selected so that epitaxial procedures and related procedures do not cause bridging between the gate electrode and the source/drain extensions. Methods of fabricating the MOSFET are described.
