Abstract :
GaAs MESFETs were fabricated using different surface pre-treatments such as photochemical passivation and RF plasma pre-treatments. Detailed electrical characterization of MESFETs was subsequently carried out. The results point out that the use of RF plasma pre-treatments is beneficial to GaAs MESFET device technology. GaAs MESFETs fabricated using RF plasma pre-treatment exhibit improved electrical characteristics and better thermal stability
