Abstract

Magnetron reactive ion etching has been receiving much attention since it offers low pressure, and low bias etching conditions with little damage. We have developed a process model for this process and present simulation results for boron trichloride etching of GaAs. The computed etch rates are uniform in the center with higher rates at the edges of the wafer. Flow rates and pressure can be optimized to improve uniformity. The etch rates with the aid of the magnetron are shown to be higher than the rates tor conventional reactive ion etching.
