Abstract:
A method of producing a micro structure on a substrate which has a support portion and a plate-like portion supported thereby at a distance from said substrate, comprising the steps of:forming a spacer layer consisting of an insulating material on a substrate having an electrically conductive layer formed on its surface, forming a latent image layer consisting of an electrically conductive material on said spacer layer at a site where said plate-like portion of a structure is to be formed, so that said latent image layer is not in contact with said electrically conductive layer, producing an aperture, where a part of said electrically conductive layer on the surface of said substrate is exposed, on said spacer layer at a site where said support portion of the structure is to be formed, forming a structure layer consisting of a metal plating film formed inside said aperture and on said latent image layer by electroplating said electrically conductive layer as a cathode in said aperture so as to reach said latent image layer, and removing said spacer layer.
