Abstract:
A method of manufacturing a stamper, comprising:a forming step for forming a photoresist layer on a surface of an electrically conductive substrate; an exposing step for exposing a desirable portion of the photoresist layer; a developing step for developing the photoresist layer; an electroforming step for electroforming a body on said surface of said electrically conductive substrate, where the photoresist layer has been removed at the developing step, of the substrate, such that said stamper includes said electrically conductive substrate and said body electroformed on said surface of said electrically conductive substrate; and a washing step for carrying out washing to remove the photoresist layer from the substrate; and wherein a thickness of the electroformed body formed at the electroforming step is equal to or less than a thickness of the photoresist layer.
