Patent ID: 7037833

Claim:
A method of forming a pattern composed of a laminated film of multiple kinds of pattern forming materials on a substrate, comprising: laminating a liquid material including the multiple kinds of pattern forming materials, onto the substrate by means of droplet ejection; placing a liquid material including an alignment mark forming material, onto the substrate by droplet ejection at least prior to a placement process of a second layer of a pattern forming material; and placing the second and subsequent layers of the pattern forming materials using a placed alignment mark, the pattern being a wiring pattern including laminated films of two kinds of pattern forming materials, in which a pattern forming material of a first layer positioned closer to a substrate side is composed of at least one of metal particles of manganese, chrome, nickel, titanium, magnesium, silicon, and vanadium; and particles containing oxide of the metal materials of the first layer; and a pattern forming material of a second layer being composed of at least one of metal particles of gold, silver, copper, palladium and nickel; and particles containing alloy of the metal materials of the second layer.
