Selective electroless plating of vias in VLSI devices |
摘要 |
Selective electroless plating of cobalt or nickel is utilized to form conductive plugs in high-aspect-ratio vias in VLSI devices. Particularly good results are obtained when an active or catalytic film is formed on the via bottoms to serve as a plating base.
