The photo-electrochemical oxidation and etching process was demonstrated in view of the damage-free etching for GaN and related materials. The photo-electrochemical oxidation was selectively conducted on the opened area of the SiO2-masked GaN surface. The Ga-oxide films were easily removed by the alkaline-treatments, where lower-damaged surface was obtained as compared with the surface obtained after the conventional dry-etching. Such low-damage etching process was very useful to fabricate the recessed-gate structure in AlGaN/GaN HEMTs. The threshold-voltage of HEMTs was precisely controlled with the etching depth with accuracy in a nanometer-range. |
