Abstract
A plug production process comprises the following steps: providing a substrate and forming at least one hole on the substrate; electroplating a metal layer on the inside of the hole and on the surface of the substrate; electrolytically polishing the metal layer; photolithographically etching the metal layer to form a substrate circuit; and coating an insulation layer on a partial surface of the substrate; in which the step of electrolytically polishing the metal layer can be performed after the step of coating the insulation layer.
