چکیده انگلیسی
Beta phase Gallium trioxide (β-Ga2O3) thin film was grown by metal organic chemical vapor deposition technology. Mixture gases of SF6 and Ar were used for dry etching of β-Ga2O3 thin film by inductively coupled plasma (ICP). The effect of SF6/Ar (etching gas) ratio on etch rate and film etching damage was studied. The etching rate and surface roughness were measured using F20-UN thin film analyzer and atomic force microscopy showing that the etching rate in the range between 30 nm/min and 35 nm/min with an improved surface roughness was obtained when the reactive mixed gas of SF6/Ar was used. The analysis of X-ray diffraction and transmission spectra further confirmed the non-destructive crystal quality. This work demonstrates that the properly proportioned mixture gases of SF6/Ar is suitable for the dry etching of β-Ga2O3 thin film by ICP and can serve as a guide for future β-Ga2O3 device processing.
