1. A method, comprising:
coating a photoresist layer on a substrate;
performing an exposure process to the photoresist layer such that the photoresist layer comprises an exposed portion;
performing a developing process to remove the exposed portion to form a patterned photoresist on the substrate;
after performing the developing process, forming a molding layer covering the patterned photoresist;
reflowing the patterned photoresist in the molding layer; and
removing the molding layer from the reflowed patterned photoresist, wherein the reflowing the patterned photoresist comprises:
heating the patterned photoresist at a temperature greater than a glass transition temperature of the patterned photoresist.
