Abstract
A computer program storage product includes instructions for forming a fin field-effect-transistor. The instructions are configured to perform a method. The method includes implanting a dopant into an exposed portion of a semiconductor substrate within a cavity. The cavity is formed in a dielectric layer on the semiconductor substrate. The cavity exposes the portion of the semiconductor substrate within the cavity. A semiconductor layer is epitaxially grown within the cavity atop the dopant implanted exposed portion of the semiconductor substrate. A height of the cavity defines a height of the epitaxially grown semiconductor.
