Abstract:
A semiconductor device, comprising:an outer surface of a semiconductor layer defining a trench isolation structure and an active region; an epitaxial layer deposited outwardly from he trench isolation structure; a first insulator layer grown outwardly from he epitaxial layer; a second insulator layer grown outwardly from the first insulator layer; a third insulator grown outwardly from the second insulator; a gate stack formed outwardly from the epitaxial layer, the gate stack comprising a portion of the first insulator layer, a portion of the econd insulator layer, a portion of the third insulator, and a gate formed proximate the third insulator layer, the gate having a narrow region and a wide region; and a source/drain implant region in the active region formed by heating the epitaxial layer to a temperature sufficient to allow for the epitaxial layer to form the source/drain implant region.
