IMPROVED STABILIZATION AND PERFORMANCE OF AUTOCATALYTIC ELECTROLESS PROCESSES

摘要

Disclosed is a method of plating a substrate with a metal using anautocatalytic electroless plating bath wherein the bath is operated above itscloud point temperature such that at least two phases are present in the bath.An autocatalytic electroless plating bath for coating silver metal is alsodescribed. A method for autocatalytic plating of silver metal directly onto asilicon surface without the need for an intervening layer of metal is alsodisclosed. The deposits of silver obtained are uniform, non-porous and haveelectrical properties . The technique can be applied for different processesand bath formulations i.e. different metals, complexing agents and reducingagents .
