Abstract:
1. A drive system for a process tool for performing electrochemical processes, the drive system comprising: a frame that is adapted to receive a substrate holder, wherein said substrate holder is adapted to hold in place a substrate at a predefined process position in an interior of said frame at a substrate height level; a movable electrode assembly that is adapted to be scanned across said predefined process position along a linear scan path and in a substantially horizontal plane; a drive assembly connected to and adapted to move said movable electrode assembly, wherein said drive assembly comprises an electric motor and a power transmission apparatus operatively coupled to said electric motor, wherein said power transmission apparatus is positioned at a first height level and extends along one outer sidewall of said frame, and wherein said first height level is above said substrate height level; and a control unit operatively coupled to said drive assembly, wherein said control unit is adapted to control movement of said movable electrode assembly along said linear scan path.
