摘要: An electroless metal deposition process to make a semiconductor device uses a plating bath solution having a reducing agent. A sample of the bath solution is taken and the pH of the sample is increased. The hydrogen evolved from the sample is measured. The hydrogen evolved is used to determine the concentration of the reducing agent present in the sample. Based on the determined reducing agent concentration, the plating bath solution is modified.

摘要: A semiconductor process is taught for performing electroless plating of copper overlying at least a portion of a layer comprising cobalt, nickel, or both cobalt and nickel. The cobalt and/or nickel comprising layer may be formed using electroless plating. For some embodiments, a tin layer is then formed overlying the copper. The tin layer may be formed using immersion plating or electroless plating. A micropad may comprise the cobalt and/or nickel comprising layer and the copper layer. In some embodiments, the micropad may also comprise the tin layer. In one embodiment, the micropad may be compressed at an elevated temperature to form a copper tin intermetallic compound which provides an interconnect between a plurality of semiconductor devices.
