Master electrode and method of forming it

Abstract

A master electrode is arranged on substrate and comprises a pattern layer at least partly of an insulating material and a first surface provided with a plurality of cavities in which a conducting material is arranged, said electrode conductor being electrically connected to at least one electrode current supply; said substrate comprising a surface contacting or adjacent said first surface and having a conductor arranged thereon, said substrate conductor being electrically connected to the at least one current supply; whereby a plurality of electrochemical cells are formed delimited by said cavities, said substrate conductor and said electrode conductor, said cells comprising an electrolyte; wherein an electrode resistance between said electrode conductor and said electrode current supply and a substrate resistance between said substrate conductor and said substrate current supply provide a predetermined current density in each electrochemical cell.
