Patent ID: 7875313

Claim:
A method to form a pattern of functional material on a substrate comprising: a) providing an elastomeric stamp having a relief structure with a raised surface; b) applying a mask material to at least the raised surface of the relief structure; c) transferring the mask material from the raised surface to the substrate forming a pattern of open area on the substrate; d) applying the functional material to at least the open area on the substrate, thereby forming an exterior surface of functional material opposite the substrate; e) contacting an adhesive to the exterior surface of the functional material; and f) separating the adhesive from the substrate to remove at least the mask material from the substrate; wherein the applying step forms a layer of functional material covering both the open area and the mask material, the method further comprising contacting another adhesive to the exterior surface, wherein the separating step first removes only the functional material covering the mask material.
