Abstract:
1. A method of manufacturing a microlens, comprising: a coating procedure coating a photosensitive polymer onto a surface of a first substrate to form a polymer film having a first surface in contact with the surface of the first substrate and a second surface; a soft bake procedure heating the polymer film; a surface exposure procedure exposing the second surface of the polymer film to a light source with an exposure level not reaching the first surface to define an exposed area and an unexposed area of the polymer film, with a mold layer being formed in the exposed area and at least one through hole of the mold layer being formed in the unexposed area; a transprint procedure pressing and abutting the mold layer onto a second substrate and heating the photosensitive polymer in the unexposed area to a temperature higher than a glass transition temperature of the photosensitive polymer for the photosensitive polymer in the unexposed area to be melted and flow through the at least one through hole, attach onto the second substrate, and form at least one microlens on a surface of the second substrate; and a solidification procedure performing an exposure to the at least one microlens and solidifying the at least one microlens to form the finished microlens.
