Abstract:
A deposition polishing system comprising:a polishing deposition machine adapted to provide an interface to control said deposition polishing system; a polishing pad component coupled to said polishing deposition machine, said polishing pad component adapted to polish and impede deposition on portions of a wafer surface; a plating bath coupled to said wafer holder, said plating bath is adapted to hold a plating solution; and a wafer holder coupled to said polishing deposition machine, said wafer holder adapted to hold said wafer inside of said plating bath, wherein said polishing pad component agitate said plating solution which enhances the redistribution of copper ions included in said plating solution and transports said plating solution to a volume inside an interconnection trench etched into said wafer.
