Claim Text:
1. A method for forming a pattern comprising: forming a processed layer on a substrate; forming an island-like metal underlayer including a first metal on the processed layer; forming a phase-separated release layer including at least a first metal, a second metal different from the first metal, and a metal oxide on the processed layer and the island-like metal underlayer; forming a mask layer on the phase-separated release layer; forming a concave-convex pattern on the mask layer; transferring the concave-convex pattern to the mask layer; transferring the concave-convex pattern to the phase-separated release layer; transferring the concave-convex pattern to the processed layer; and dissolving the phase-separated release layer using a peeling liquid for dissolving the first metal and the second metal and removing the mask layer from the processed layer to expose the concave-convex pattern comprised of the processed layer.
