Abstract
Vertically stacked Field Effect Transistors (FETs) are created where a first FET and a second FET are controllable independently. The vertically stacked FETs may be connected in series or in parallel, thereby suitable for use as a portion of a NAND circuit or a NOR circuit. Epitaxial growth over a source and drain of a first FET, and having similar doping to the source and drain of the first FET provide a source and drain of a second FET. An additional epitaxial growth of a type opposite the doping of the source and drain of the first FET provides a body for the second FET.
