The reactive ion etching of GaAs has been investigated in BCl3 plasma discharges. Etching rates have been characterized as functions of pressure (10–25 mTorr), power density (∼0.05–0.5W/cm2), and Cl2/BCl3 gas compositions. Rates of ∼12–20 nm/min have been obtained, and are significantly lower than for other chlorinated plasmas. Etching profiles exhibit a high degree of anisotropy and smooth surface morphologies.
