Abstract
A method for fabricating a micro-lens mold comprises forming a thick film on a substrate, patterning the thick film to form a micro-capillary, filling the micro-capillary with a heat curing glue liquor, rotating the substrate so that the liquid in the micro-capillary presents a circular arc shape as a micro-lens because of the surface tension of the material itself and the adhesion of the micro-capillary, and curing and shaping the heat curing glue liquor by the irradiation of a light source or by heating.
