Patent ID: 7241372

Claim:
A method for removing plating liquid from a substrate-contacting portion, or its vicinity, of a sealing member at an inner circumferential edge of a substrate holding member, said method comprising: while supporting a substrate on said sealing member, within a housing having said substrate holding member, rotating said substrate holding member, and thereby rotating said sealing member, to remove plating liquid from said substrate and said sealing member; removing said substrate from said housing; then moving a nozzle head toward said housing such that said nozzle head is positioned close to said substrate-contacting portion of said sealing member, said nozzle head having a plating liquid suction nozzle and a cleaning liquid injection nozzle; while rotating said substrate holding member, and thereby rotating said sealing member, sucking plating liquid remaining on said substrate-contacting portion, or its vicinity, of said sealing member via said plating liquid suction nozzle; and while sucking plating liquid remaining on said substrate-contacting portion, or its vicinity, of said sealing member, (i) ejecting cleaning liquid toward said substrate-contacting portion, or its vicinity, of said sealing member via said cleaning liquid ejection nozzle, and (ii) sucking the cleaning liquid from said substrate-contacting portion, or its vicinity, of said sealing member via said plating liquid suction nozzle.
