Latest Patents
Cheng holds a patent titled "Method and apparatus for stabilizing plating film impurities." This patent describes a method for stabilizing plating film impurities in an electrochemical plating bath solution. The process involves providing an electrochemical plating machine where the plating process occurs. A by-product bath solution is created by continually removing a pre-filtered bath solution from the machine and eliminating an additive from it. A clean bath solution is formed by removing an additive by-product from the by-product bath solution. Additionally, an additive bath solution is created by adding a fresh additive to the clean bath solution, which is then introduced back into the electrochemical plating machine. This innovative method enhances the stability of film impurities, thereby improving the overall plating process.
