摘要：
We report an experimental study of GaAs etching by ICP-RIE based on Cl-2:N-2 chemistry. The influence of the RF source power, the chlorine dilution, the RF platen power, and the process pressure at several substrate temperatures are investigated. An optimized process is proposed to get routinely GaAs nanowires of 1 mu m high and about 30 nm in diameter with a full top-down approach combining electron beam lithography and Ni lift-off steps.
