Patent ID: 7288156

Claim:
In a substrate processing chamber, a method for cleaning a substrate having one of a resist film and a polymer residue on a surface of said substrate, comprising: providing a water vapor producing arrangement that includes at least a heating arrangement for heating water to produce water vapor and a first aperture configured to supply said water vapor at a first temperature to said surface of said substrate; and providing a water mist producing arrangement including at least a second aperture configured to supply a water mist containing a gas and water particles to said surface of said substrate, said water mist being supplied to said surface substrate at a second temperature lower than said first temperature; supplying said water vapor to said surface of said substrate; and thereafter supplying said water mist to said surface of said substrate after supplying said water vapor has started, wherein said water mist is configured to at least partially peel said one of said resist film and said polymer residue.
