Patent ID: 7040961

Claim:
A method for manufacturing an article, the article having a resist layer to be used and removed during manufacture of the article, comprising the steps of: carrying out an implant process on the article via the resist layer; and removing the resist layer and residues remaining after the implant process by: generating free radicals from one or more reactant gases remote from the article, wherein the article is contained in a processing chamber; introducing the free radicals into proximity of the article in the processing chamber, wherein the free radicals react with the resist layer and residues remaining after the implant process; and supplying a cryogenic cleaning medium into the processing chamber, wherein the cryogenic cleaning medium removes residue present after the free radicals react with the resist layer and residues remaining after the implant process; wherein the reactant gases are selected to result in residue having weakened bonds, wherein the residue is removed with the cryogenic cleaning medium; wherein the resist layer and residues are removed from the article.
