Abstract

Official abstract text for this publication.

The present invention relates to a copper oxide solid for use in plating of a substrate using an insoluble anode. Further the present invention relates to a method of producing the copper oxide solid. Further the present invention relates to an apparatus for supplying a plating solution in which the copper oxide solid is dissolved into a plating tank. A copper oxide solid (CS) to be supplied into a plating solution for plating a substrate (W) includes a copper oxide powder and a liquid as a binder to solidify the copper oxide powder.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of producing a copper oxide solid to be supplied into a plating solution for plating a substrate, comprising: an addition step of adding a liquid to a copper oxide powder, the liquid comprising the plating solution to which no additives have been added; and a compression molding step of compression-molding the copper oxide powder with the liquid added. 2. The method according to claim 1 , further comprising: a first compression molding step of compression-molding the copper oxide powder with a first compressive force, the first compression molding step being performed before the addition step, and wherein the compression molding step of compression-molding the copper oxide powder after the addition step is a second compression molding step of compression-molding the copper oxide powder with a second compressive force. 3. The method according to claim 1 , wherein the compression molding step is performed using a press mold having a concavo-convex shape.
