Abstract:
1. An apparatus comprising: a semiconductor substrate; a first Field Effect Transistor (FET) on the semiconductor substrate, the first FET further comprising a first source, a first drain, a first gate dielectric, a first body, and a first gate electrode, the first gate electrode coupled to a first source of a first logical signal; a second FET, the second FET further comprising a second source, a second drain, a second gate dielectric, a second body, and a second gate electrode, the second gate electrode coupled to a second source of a second logical signal, the second source of the second logical signal not being the first source of the first logical signal, the second gate electrode being above the first gate electrode relative to a top surface of the semiconductor substrate; a first epitaxial layer of similar doping as the first drain and the first source, the first epitaxial layer grown over the first drain and the first source; an oxide created over the first source to electrically isolate the first source from the first epitaxial layer over the first source; and a second epitaxial layer of opposite doping as the first drain and the first source grown over the first epitaxial growth, the first epitaxial layer comprising the second drain and the second source, and the second epitaxial growth forming the second body.
