Abstract: A metal film having a predetermined thickness profile is obtained on a surface of an article through electroplating. The electroplating of the metal film on the article is done with an apparatus including a plurality of modifying electrodes and a body of plating material suspended in a plating solution. Electrical potentials are established at the article to be plated, the body of plating material, and at each one of the modifying electrodes. The particular electrical potential at the article, the body of plating material and at each one of the modifying electrodes is chosen to provide differences in electrical potential which result in a metal film having the predetermined thickness profile.
