Title:
MICROSTRUCTURE AND ITS FABRICATION METHOD, SENSOR DEVICE, AND RAMAN SPECTROSCOPY DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/010442
Kind Code:
A1
Abstract:
[PROBLEMS] To simply fabricate a microstructure, which has a plurality of metal
particles firmly fixed and arranged in recesses of an uneven metal substrate,
on the uneven metal substrate having the uneven surface structure. [MEANS FOR
SOLVING PROBLEMS] A microstructure (1) is fabricated by the following process
steps (A, B, C) performed in sequence. In the step (A), an uneven metal substrate
(11) having an uneven surface structure is prepared as a metal substrate. In
the step (B), a metal film (21) including a metal different from the metal structuring
the uneven metal substrate (11) as a primary component is formed on the surface
of the uneven metal substrate (11). In the step (C), the metal structuring the
metal film (21) is aggregated into particles by annealing.
