Abstract

Electroless plating is performed to deposit conductive materials on work pieces such as partially fabricated integrated circuits. Components of an electroless plating bath are separately applied to a work piece by spin coating to produce a very thin conductive layer (in the range of a few hundred angstroms). The components are typically a reducing agent and a metal source.
