ABSTRACT:
An oxide layer is thermally grown over a semiconductor body, and openings are etched in the oxide layer to expose portions of the surface of the semiconductor body. Then, epitaxial regions are grown from the semiconductor body into the openings in the oxide layer, which epitaxial regions will eventually become the active regions of devices.
