  • Plating catalyst and method
    Patent number: 10066299
    Abstract: A solution including a precious metal nanoparticle and a polymer polymerized from at least two monomers, (1) a monomer having two or more carboxyl groups or carboxyl acid salt groups and (2) a monomer which has ? electron-available features. The solution is useful for a catalyst of a process for electroless plating a metal on non-conductive surface.
    Type: Grant
    Filed: February 24, 2013
    Date of Patent: September 4, 2018
    Assignee: ROHM AND HAAS ELECTRONIC MATERIALS LLC
    Inventors: Suk Kwan Kwong, Weijuan Zhou, Wenjia Zhou, Dennis Chit Yiu Chan, Dennis Kwok-Wai Yee
