Abstract
A processing apparatus includes a first chamber having a gas first inlet and a first gas outlet, a plasma generator that generates a plasma in the first chamber, and a second chamber having a second gas inlet and a second gas outlet. A control unit controls the first inlet to provide a carbon containing gas to the first chamber and control the plasma generator to apply a first plasma to a silicon-containing film of a substrate to a first depth. The control unit controls the second gas inlet to apply another gas inside the second chamber and deposit a second part of the protection film over the first part of the protection film. The control unit controls a supply of a fluorocarbon gas through the first gas inlet and control the plasma generator to generate a second plasma to etch the silicon-containing film to a second depth.
