Abstract
A selectivity study of the etching of lattice matched (LM) InCaAs/InAl As on InP and metamorphic (MM) InGaAs/InAlAs on GaAs in succinic acid: hydrogen peroxide solutions is reported. Selectivities as high as 70 and 1030 are? respectively, obtained for the LM and MM InGaAs on InAlA s. Observations and measurements with an atomic force microscope of na rrow recess and under-resist etch on LM InP materials are also present ed. The ability of these solutions for fabrication of InGaAs/InAlAs he terojunction field effect transistors is discussed. (C) 1996 American Vacuum Society.
