Patent ID: 8287781

Claim:
An imprinting method for making optical components, comprising: providing an imprinting mold, the imprinting mold comprising a molding surface, a molding portion formed on the molding surface, a first alignment mark formed on the molding surface with a location different from that of the molding portion; providing a transparent substrate comprising a first surface, the first surface comprising a plurality of supporting areas arranged in an array, each of the supporting areas configured for supporting a mass of molding material; applying a mass of molding material on each of the supporting areas; pressing the imprinting mold on each mass of the molding material; solidifying the imprinted molding material to form the optical components and a second alignment mark, the second alignment mark being formed on the first surface of the substrate by the first alignment mark; forming a transparent film on a second surface of the substrate, the second surface opposite to the first surface; positioning the imprinting mold to face the transparent film; aligning the first alignment mark with the second alignment mark; pressing the imprinting mold on the transparent film with respect to the optical components on the first surface; and solidifying the imprinted transparent film.
