III-V compound semiconductor MOSFETs using Ga/sub 2/O/sub 3/(Gd/sub 2/O/sub 3/) as gate dielectric

We report a III-V based metal oxide semiconductor field effect transistor (MOSFET) technology using Ga/sub 2/O/sub 3/(Gd/sub 2/O/sub 3/) as the gate insulator. Enhancement-mode p- and n-channel, depletion-mode n-channel GaAs MOSFETs, and enhancement-mode n-channel In/sub 0.53/Ga/sub 0.47/As MOSFETs were demonstrated.
