摘要: An improved method for removing a photoresist mask from an etched aluminum pattern after etching the pattern in a chlorine containing plasma has been created. The method is a two step process, in which a first stripping step is in a plasma containing O.sub.2 and H.sub.2 O and a second stripping step is in a plasma containing O.sub.2.
