Patent ID: 8492077

Claim:
A method for providing a conductive material structure on a carrier comprising: applying a photo sensitive material on the carrier; applying a mask on said photo sensitive material, the mask defining a conductive material structure to be formed on the carrier; irradiating the defined structure on the carrier in order to prepare for metallization; metalizing the defined structure for forming the conductive material structure; covering the formed conductive material structure with an environmental protection layer except for in a set of pre-specified areas, where said set of pre-specified areas includes at least one contact area on the conductive material structure; and placing electrical contact enhancing material on said contact area, which placing of electrical contact enhancing material is performed after the conductive material structure has been covered with the environmental protection layer; wherein: the carrier comprises a dielectric substrate; applying a photo sensitive material on the carrier comprises pad or screen printing said photo sensitive material directly on the dielectric substrate; and applying a mask on said photo sensitive material comprises selectively pad or screen printing said mask on said photo sensitive material.
