  • Publication number: 20210040641
    Abstract: Provided is a plating apparatus for plating a substrate, which prevents deterioration of uniformity of plating film thickness caused by an oxide film created at an edge section of the substrate and/or an organic substance attached to the edge section of the substrate. The plating apparatus includes a plating bath for applying a voltage to the substrate set in a substrate holder to plate the substrate; and an edge section washing device that locally removes at least either of the organic substance and the oxide film present at the edge section of the substrate before the substrate is set in the substrate holder.

  • Publication number: 20200165737
    Abstract: Soluble copper oxide powder capable of preventing a decrease in quality of a copper film formed by plating is disclosed. The copper oxide powder contains copper and impurities including sodium. A concentration of the sodium is not more than 20 ppm. The copper oxide powder is regularly supplied into a plating solution. A voltage is applied between an insoluble anode and a substrate immersed in the plating solution, thereby plating the substrate.
