Sapphire is used as the substrate in the production of Silicon-on-Sapphire (SoS) wafers used in the production of high-performance radio frequency integrated circuits (RFICs). Mobile devices, smart phones and other electronics benefit from SoS RFICs through reduced energy consumption, improved performance, and smaller form factors – as compared to less efficient RFIC technologies.

SoS RFICs are produced on larger-diameter R-plane sapphire substrates and offer a more environmentally-friendly alternative to arsenic-based Gallium Arsenide (GaAs) wafers. Rubicon Technology provides six- and eight-inch polished sapphire wafers for production of SoS RFICs, with other sizes available upon request.
