Abstract

This study has provided considerable insight into the impact of device down scaling on the characteristics of RF devices. This type of RF devices, featuring a thin p-layer based on a semi-insulating substrate, is free from the unwanted parasitic effects resulting from traditional conducting substrates. We fabricated 4H-SiC RF MOSFETs with fT/fMAX of 0.7/1.5 GHz and, in so doing, identified the key issues associated with short channel effects, influencing device mobility and the RF characteristics of RF MOSFETs on a semi-insulating substrate.
