AbstractAlGaAs/GaAs based high electron mobility transistors (HEMTs) with Cu/Ti metallized gates have been fabricated. Copper gates were used to achieve low gate resistance and to minimize the hydrogen induced device degradation. The DC measurement of the processed AlGaAs/GaAs HEMTs with Cu/Ti gates shows comparable performance to similar Au based GaAs HEMTs. The Cu-based HEMTs were also subjected to elevated temperature testing under 5% H2 –N2 forming gas up to 250°C and 8 hours and no degradation due to hydrogen effects was found.
