Abstract
The present invention relates to aqueous, alkaline plating bath compositions for electroless deposition of ternary and quaternary cobalt alloys Co-M-P, Co-M-B and Co-M-B—P, wherein M is selected from the group consisting of Mn, Zr, Re, Mo, Ta and W which comprise a propargyl derivative as the stabilizing agent. The cobalt alloy layers derived there from are useful as barrier layers and cap layers in electronic devices such as semiconducting devices, printed circuit boards, and IC substrates.
