Abstract

A device and method for imprinting a metal member using an external electric field and an IR band laser transmissive mold method are provided. The device includes a laser-beam generating device spaced apart from a surface of the metal member that is to be imprinted, and generating a laser beam of an IR band to radiate the laser beam onto the metal member surface, an electric-field forming device forming an electric field between both side surfaces of the metal member perpendicular to a direction in which the laser beam is incident, and a mold made of a material through which the laser beam may be transmitted, having on a surface thereof a fine pattern to form the fine pattern on the metal member surface, and performing an imprinting operation while coming into contact with the metal member surface that is softened by irradiation of the laser beam.
