Abstract

We report on the development of mm-wave GaN-on-Si AlGaN HEMTs integrated with a 3 level Cu damascene BEOL flow on 200mm Si <111> wafers. Optimizations of the gate metal stack, contact resistance and gate length scaling to 110nm result in devices with a peak gm of 430 mS/mm and an fMAX of 135 GHz. While wafer warp was found to increase slightly through the processing of 3 levels of 1μm thick Cu metal, no significant deterioration was observed between devices measured at Metal 1 and Metal 3.
