COLLOID CRYSTAL, FILM-SHAPED PARTICULATE STRUCTURE, FILM-SHAPED PERIODIC STRUCTURE AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To confirm the state of particle arrangement in a colloid crystal stage, and to confirm a proceeding state in a subsequent transfer step to be carried out even from a film surface direction and to enable a colloid crystal, a particulate structure and a periodic structure to be utilized even from the film surface direction.;SOLUTION: Ruggedness in which |cosθ|=1/3 or |cosθ|=1 when an angle between faces is θ is formed on a silicon substrate. After nickel electrocasting is carried out thereon, exfoliation from the silicon substrate is performed to produce a nickel mold where the ruggedness is transferred. A UV curing type resin is applied on a transparent substrate and then the nickel mold is pressed thereon to obtain a transparent substrate where the silicon ruggedness is transferred. These two pieces of transparent substrates 513, 513a are superposed with the rugged surfaces facing each other and by holding a spacer 504 therebetween to produce a structure 501 having a minute space 508. Its lower end is dipped in a particulate dispersed liquid to introduce and accumulate the particulates in the minute space. Thus the colloid crystal is obtained. The film-shaped particulate structure is obtained by evaporating a solvent and further the film-shaped periodic structure is obtained by removing the particulates.;COPYRIGHT: (C)2007,JPO&INPIT
