GaN, AlxGa1-xN and InxGa1-xN were prepared by dry etching with Cl2/Ar/O2 plasma. The etch rates and selectivities were determined for the nitrides using an inductively-coupled plasma reactor. Results showed that the oxygen flow rate and the plasma parameters significantly affected the etch characteristics of the semiconductors.
