Inductively coupled plasma etching of gan
WebA systematic study of the nonselective and smooth etching of GaN/AlGaN heterostructures was performed using Cl 2 /Ar/BCl 3 inductively coupled plasmas (ICP). Nonselective etching can be realized by adjusting the BCl 3 ratio in the Cl 2 /Ar/BCl 3 mixture (20%–60% WebIn this study, planar inductively coupled Cl2 /Ar and Cl2 /BCl3 plasmas were used to etch n-GaN, and the effects of process parameters such as gas combination and gas pres …
