Abstract
A radio frequency (RF) switch includes a heating element, thermally conductive and electrically insulating layer over the heating element, a wetting dielectric layer over the thermally conductive and electrically insulating layer, and a phase-change material (PCM) over the wetting dielectric layer. At least one cladding dielectric layer can be situated over sides and/or over a top surface of the PCM. Each of the wetting dielectric layer, phase change material, and cladding dielectric layer can comprise at least germanium. A transitional dielectric layer can be situated between the thermally conductive and electrically insulating layer and the wetting dielectric layer. A contact uniformity support layer can be situated over the cladding dielectric layer.
