Claim:
1. A method of removing photoresist scum and electroplating metal into photoresist features, the method comprising: (a) receiving a substrate in a multi-tool electroplating apparatus, the multi-tool electroplating apparatus comprising: (b) generating a reducing plasma from a reducing plasma generation gas in the plasma generation chamber; (c) flowing the reducing plasma from the plasma generation chamber into the plasma treatment chamber to thereby expose the substrate to the reducing plasma, react the photoresist scum with the reducing plasma, and remove at least a portion of the photoresist scum; and (d) transferring the substrate to the electroplating module and electroplating metal on the metal seed layer in the photoresist features.
