Abstract:
In a plasma processing method, a carbon-containing film is formed on surfaces of components in a chamber by using a plasma of a carbon-containing gas, and a silicon-containing film whose film thickness is determined based on a film thickness of the carbon-containing film is formed on a surface of the carbon-containing film by a silicon-containing gas. Then, a target object is loaded into the chamber and processed by a plasma of a processing gas after the formation of the silicon-containing film. The silicon-containing film is removed from the surface of the carbon-containing film by using a plasma of a fluorine-containing gas after the target object processed by the plasma is unloaded from the chamber, and the carbon-containing film is removed from the surfaces of the components by using a plasma of an oxygen-containing gas.

Claim (Index 1):
A plasma processing method comprising:\n a first film forming step of forming a carbon-containing film on surfaces of components in a chamber by using a plasma of a carbon-containing gas; a second film forming step of forming a silicon-containing film whose film thickness is determined based on a film thickness of the carbon-containing film on a surface of the carbon-containing film by a silicon-containing gas; a plasma processing step of processing a target object loaded into the chamber by using a plasma of a processing gas after the formation of the silicon-containing film; a first removal step of removing the silicon-containing film from the surface of the carbon-containing film by using a plasma of a fluorine-containing gas after the target object processed by the plasma is unloaded from the chamber; and a second removal step of removing the carbon-containing film from the surfaces of the components by using a plasma of an oxygen-containing gas.
