Patent ID: 7338753

Claim:
A method of manufacturing a metal microstructure comprising the steps of: forming a resin mold having a concave portion; attaching on a conductive substrate a concave surface of said resin mold having a concave portion by interposing a photosensitive polymer having a chemical composition changed by one of the group consisting of an electron beam, ultraviolet radiation and visible radiation so as to form a layered structure having said resin mold; polishing said resin mold having a concave portion so as to form a resin mold having a vacant portion penetrating in direction of thickness; exposing said layered structure having said resin mold to said one of the group consisting of said electron beam, said ultraviolet radiation and said visible radiation; removing an exposed photosensitive polymer existing at the vacant portion of said resin mold; and filling with a metal the vacant portion of said layered structure having said resin mold by electroforming.
