Latest Patents

Toru Negishi holds a patent for a nickel or nickel alloy electroplating bath and plating process. This patent, which is particularly useful for electroplating conductors that are partially masked with an organic high-molecular resist layer, describes a nickel electroplating bath that contains a water-soluble nickel salt. The nickel alloy electroplating bath includes both a water-soluble nickel salt and a water-soluble salt of a metal that can be alloyed with nickel. The electroplating bath is enhanced with an electrical conductive salt that contains cations such as ammonium, magnesium, calcium, aluminum, and barium ions, while substantially excluding sodium and potassium ions. This innovation allows for effective electroplating without the risk of floating the resist layer.
