Abstract:
1. A microstructure manufacturing method comprising: (a) generating first light including an interference fringe by crossing two laser beams; (b) forming a denatured region and a non-denatured region on an object having thermal non-linearity by applying the first light onto the object, so that the denatured region and the non-denatured region are disposed so as to correspond to a period of the interference fringe of the first light; (c) etching the object so that the denatured region or the non-denatured region is selectively eliminated; and during step (b) and before step (c), (d) generating second light including an interference fringe by making a phase difference between the two laser beams and then crossing the two laser beams; and (e) forming a denatured region and a non-denatured region by applying the second light onto the object, so that the denatured region and the non-denatured region are disposed so as to correspond to a period of the interference fringe of the second light; and wherein: the denatured region is a crystalline region and the non-denatured region is a non-crystalline region and wherein the object consists essentially of PtO, ZnS—SiO in step (d), a third light as well as the second light is applied onto the object, wherein the first light, second light and the third light are different.
