Inductively coupled plasma etching of InP in N-2/H-2 is demonstrated. The d
ependence of etch rates on N-2/H-2 composition, radio frequency power and e
tching pressure is presented. An optimized process is developed and shown t
o be suitable for the slow, well-controlled, etching of InP-based nanostruc
tures, while yielding excellent surface morphology. (C) 2001 American Insti
