MICROSTRUCTURE AND ITS FABRICATION METHOD, SENSOR DEVICE, AND RAMAN SPECTROSCOPY DEVICE

摘要

In order to simply produce a microstructured body (1) in which metal particles (20) are arranged so as to be fixed to depressions (12) of a metal substrate (11) having at a surface a structure of protrusions and the depressions, a process for producing the microstructured body (1) includes the steps of: (A) preparing a metal substrate (11) with a surface having a structure of protrusions and depressions; (B) forming a metal film (21) on the surface of the metal substrate (11), where the metal film (21) contains as the main component a metal different from the constituent metal of the metal substrate (11); and (C) annealing the metal film (21) so that the constituent metal of the metal film (21) is coagulated into particles (20) .
