発明の名称 (英語) Substrate with microfine metallic lumps arranged on surface
発明の概要(英語)

The objective is to present a metal nanostructure having metal masses with zero valence aligned on a substrate surface wherein the size and shape of the metal masses are controlled and a manufacturing process thereof. A micro phase separation membrane comprising an amphiphilic block copolymer assumes a state that contains numerous micro diameter hydrophilic cylinders inside the membrane in the direction perpendicular to the membrane surface. The membrane is prepared using a solution containing an amphiphilic block copolymer and desired metal ions or by bringing a micro phase separation membrane of an amphiphilic block copolymer in contact with a solution containing metal ions after the membrane is formed to localize the metal ions in the hydrophilic micro diameter cylinders.

A substrate containing numerous zero valence metal masses in approximately pillar shapes, approximately dot shapes or combinations of these at set intervals can be obtained by conducting a reduction treatment and a treatment to remove organic materials on the micro phase separation membrane. As the treatment, ultraviolet light irradiation or electron beam irradiation, plasma treatments, chemical reduction processes or electrochemical reduction processes may be used.
