We report the processing and DC and microwave characteristics of a novel thin-film silicon-on-sapphire MOS transistor which utilizes a sidewall process to realize a deep sub-micron gate length without the use of lithography. The device also incorporates an asymmetric lightly doped drain region for high breakdown voltage. Devices with 0.15 and 0.25 μm gate lengths have been fabricated. A FET with a 0.25 μm gate length and 1.0 μm LDD length had an ft=9 GHz, fmax=27 GHz and breakdown voltage of 13 volts
