Chemical contribution of oxygen to silicon carbide plasma etching kinetics in a distributed electron cyclotron resonance (DECR) reactor

Etching experiments are performed in a distributed ECR reactor on both 3C- and 6H-SiC. An SF6/O2 gas mixture, F saturation conditions, and constant ion bombardment energy and flux are used, allowing the study of O2 contribution exclusively. In these conditions, results demonstrate the neutrality of...

Zusammenfassung:Etching experiments are performed in a distributed ECR reactor on both 3C- and 6H-SiC. An SF6/O2 gas mixture, F saturation conditions, and constant ion bombardment energy and flux are used, allowing the study of O2 contribution exclusively. In these conditions, results demonstrate the neutrality of O2 on SiC etching mechanisms. 21 refs.
