Resumo
The kinetics of GaAs etching in CF2Cl2 and CF2Cl2/N2 is investigated. It is shown that the shape of the dependences of the etching rate on the gas flow rate is determined by the energy of the ions bombarding the treated surface. It is demonstrated that, when a plasma-forming gas is diluted in a ratio of 1/1, the etching rate of the sample decreases by a factor of approximately 1.6. An increase in power (Wrf or Wbias) leads to significant changes in the GaAs etching rate.
