Patent ID: 6849547

Claim:
A process for removing a metallized surface from a workpiece, wherein a kinetic removal mechanism for removal of said metallized surface is characterized by a formation step for formation of a removable surface film surface and an abrasive step for removal of said film, said process comprising: causing said workpiece to contact a polishing member while effecting relative motion between said workpiece and said polishing member; causing a polishing solution having less than 1 wt % of a polishing abrasive to be distributed at a contact area between said workpiece and said polishing member through at least one bore formed in a platen connected to said polishing member to affect a removal rate for removal of said film during said abrasive step; establishing a temperature at said contact area by heating or cooling said polishing solution before causing said polishing solution to be distributed to said contact area; and controlling the temperature at said contact area by circulating a heat exchange fluid through at least a portion of said platen.
