Abstract:
1. A reactor for electrochemically processing a microelectronic workpiece, the reactor comprising: a reactor head assembly including a workpiece contact for providing electrochemical processing power to a surface of a workpiece held by the reactor head assembly, the reactor head assembly being movable between a workpiece loading/unloading position and a workpiece processing position; a reactor base assembly including a movable electrode assembly having an electrode surface that is movable along a plane that is generally parallel to the surface of a workpiece held by the reactor head assembly when the reactor head assembly is in the workpiece processing position; and a gap adjustment assembly disposed on the reactor base assembly to mechanically adjust the spacing that is present between the electrode surface and the surface of the microelectronic workpiece, including a central region of the workpiece surface, during processing thereof.
