Extract

Dry etching of indium-based III–V materials in chlorine-based gases is difficult because of the low vapor pressure of the indium chloride by-product. Recently, reactive ion etching of InP(1,2), and GaAs(3,4) using methane, hydrogen and argon mixture in which volatile organometallic group III compounds are formed has been employed. In this paper, we report the reactive ion etching of indium-based materials using CH4:H2:Ar and SiCl4:Ar mixtures.
