Patent ID: 8741380

Claim:
A process for producing a fine metal structure having a surface furnished with microprojections having a thickness or equivalent diameter ranging from 10 nanometers to 10 micrometers and a ratio of a height (H) of the microprojections to the equivalent diameter (D), H/D, being greater than 1, comprising the steps of: providing a substrate having a surface, a fine rugged pattern formed on the substrate surface; applying a molecular electroless plating catalyst having atoms dissolved in a solution, in a state of a complex or a salt, to the substrate surface; forming a catalyst layer with catalyst molecules being absorbed on the substrate surface; thereafter carrying out electroless plating to form a metal layer filling the fine rugged pattern; forming a support layer on a surface on a backside of the metal layer; and detaching the metal layer from the substrate to obtain the fine metal structure furnished with a surface having undergone reversal transfer of the rugged pattern.
