    摘要: A method of plating a metal layer on a work piece includes exposing a surface of the work piece to a plating solution, and supplying a first voltage at a negative end of a power supply source to an edge portion of the work piece. A second voltage is supplied to an inner portion of the work piece, wherein the inner portion is closer to a center of the work piece than the edge portion. A positive end of the power supply source is connected to a metal plate, wherein the metal plate and the work piece are spaced apart from each other by, and are in contact with, the plating solution.

    摘要: Presented herein is a method for electrolessly forming a metal cap in a via opening, comprising bringing a via into contact with metal solution, the via disposed in an opening in a substrate, and forming a metal cap in the opening and in contact with the via, the metal cap formed by an electroless chemical reaction. A metal solution may be applied to the via to form the metal cap. The metal solution may comprises at least cobalt and the cap may comprise at least cobalt, and may optionally further comprise tungsten, and wherein the forming the cap comprises forming the cap to further comprise at least tungsten. The metal solution may further comprise at least hypophosphite or dimethylaminoborane.
