    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.
