Abstract:
1. A molding method for making an element with a microscopic structure, comprising the steps of: setting a temperature of a mold, having a microscopic shape, at a value higher than a glass transition temperature of a material being deformable with heat; pushing said mold against said material at a first velocity, after said material is positioned opposite to said mold so that said microscopic shape contacts said material; establishing a first pressure application period, during which a moving velocity of said mold is maintained at zero; pushing said mold against said material at a second velocity being faster than said first velocity; and releasing said mold from said material wherein the larger an aspect ratio of said microscopic shape is, the slower said first velocity is to facilitate the accurate transfer of microscopic shapes having a large aspect ratio.
