Claim Text:
1. A method comprising the steps of: providing a first dielectric layer including a first opening on a first surface of a semiconductor layer, such that the first opening defines an exposed portion of the first surface of the semiconductor layer; providing a second dielectric layer on a surface of the first dielectric layer opposite the semiconductor layer and in the first opening; removing a first portion of the second dielectric layer, such that a second portion of the second dielectric layer remains in the first opening; substantially removing the first dielectric layer; growing an epitaxial layer on the exposed portion of the first surface of the semiconductor layer not covered by the second portion of the second dielectric layer; and removing the second portion of the second dielectric layer to define one or more contact windows in the epitaxial insulating layer through which a portion of the first surface of the semiconductor layer is exposed.
