Abstract: A semiconductor device includes a semiconductor substrate, a phase change switching device formed over the semiconductor substrate and including a strip of phase change material connected between an RF input contact and an RF output contact, and a heating element thermally coupled to the strip of phase change material, and a silicon adhesion layer that forms a direct interface with a first surface of the strip of phase change material and separates the first surface from a dielectric material formed thereon.
