Method for manufacturing site-selectively modified micro-and nanostructures

摘要

It is an object of the present invention to provide a method which can easily and selectively modify specific sites on indentations or protrusions of indentation/protrusion structures fabricated by nanoimprinting. Pressing a mold having indentation/protrusion structures onto a polymer substrate comprising at least two layers of different chemical composition exposes the second layer, which has been covered by the outermost layer, in pillars formed as a result of the pressing. Site-specific chemical modification of the pillars can be achieved by formulating a desired chemical composition for the second layer beforehand, or by chemical modification of the exposed second layer cross-sections in the pillars.
