Title:
ELECTROLYTIC PROCESSING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO2003029531
Kind Code:
A3
Abstract:
There is provided an electrolytic processing apparatus and method which, while omitting a CMP treatment entirely or reducing a load upon a CMP treatment to the least possible extent, can process a conductive material formed in the surface of a substrate to flatten the material, or can remove (clean) extraneous matter adhering to the surface of a workpiece such as a substrate. The electrolytic processing apparatus includes: a pair of electrodes disposed at a given distance; an ion exchange disposed between the pair of electrodes; and a liquid supply section for supplying a liquid between the pair of electrodes. The electrolytic processing method includes: providing an electrode section having a pair of electrodes disposed at a given distance with an ion exchanger being interposed; and bringing the electrode into contact with or close to a workpiece while supplying a fluid to the ion exchanger, thereby processing the surface of the workpiece.
