| Abstract: | Etchings of CVD diamond films using oxygen plasmas produced by DC glow discharge, microwave discharge and electron cyclotron resonance（ECR）discharge are investigated. The surface morphologies of the diamond films before and after etching by three kinds of plasmas are analyzed using scanning electron microscopy. The etching mechanisms of etching are discussed respectively through comparing the differences of the morphology of the etched diamond films. Finally, etching models are developed according to the theories of plasma sheath. |
