Abstract
To increase a schottky barrier height (SBH) for In0.52AlAs layer, in-situ Ar plasma pre-treatment method was proposed. Through the pre-treatment of Ar plasma before schottky metallization, a SBH of + 1.05 eV for In0.52AlAs layer was obtained by C-V measurement for a vertical type schottky diode. It was thought to be an effective removal of native oxide on InAlAs layer. More pre-treatment would result in a decrease of SBH due to a plasma induced damage effect. This process was applied to fabricate In0.52AlAs/In0.53GaAs/InP HEMT, which led to an improvement in sub-threshold leakage, sub-threshold swing and reverse breakdown voltage characteristics.
