Abstract
We have investigated RIBE processes for etching InP and related materials using the non-corrosive CH4/H2/Ar gas chemistry. The etch rates, surface morphology and etch profiles and have been studied as a function of plasma parameters and gas mixtures. The equipment has been an inductively coupled RF ion gun with a two grid extraction system. Chamber pressure during the process has been about 10 -4 mbar. Sample temperatures depended somewhat on the energy and etch time but were always maintained below 100 C
