Abstract

A plating method and apparatus for a substrate fills a metal, e.g., copper, into a fine interconnection pattern formed in a semiconductor substrate. The apparatus has a substrate holding portionhorizontally holding and rotating a substrate with its surface to be plated facing upward. A seal materialcontacts a peripheral edge portion of the surface, sealing the portion in a watertight manner. A cathode electrodepasses an electric current upon contact with the substrate. A cathode portionrotates integrally with the substrate holding portionAn electrode arm portionis above the cathode portionand movable horizontally and vertically and has an anodeface-down. Plating liquid is poured into a space between the surface to be plated and the anodebrought close to the surface to be plated. Thus, plating treatment and treatments incidental thereto can be performed by a single unit.
