Conductive pattern producing method and its applications

Abstract

An improved method of forming an electrode pattern on a substrate is described. The substrate is coated with a first conductive film and subjected to baking. On the first conductive film is then overlied a second conductive film which mends possible fissures of the first conductive film which, besides, would produce open circuits in the pattern.

1 . A method for producing an electrode pattern on a substrate comprising: 
 coating said substrate with a first conductive film in the form of an electrode pattern for circuitry; and    coating said substrate with a second conductive film overlying said first conductive film, said second conductive film being designed to function as a complete pattern for said circuitry even if it were not for said first conductive film.
