Abstract:
1. A method for manufacturing a polymer miniature lens on a substrate, the method comprising: forming a lens forming pattern on the surface of the substrate, the lens forming pattern having a periphery area and an interior area, most portion of the periphery area having a property of confining liquid polymer, while the interior area having at least one portion exposing the surface of the substrate; depositing liquid polymer onto the lens forming pattern; and curing the liquid polymer after the liquid polymer reaches equilibrium shape and is confined to the periphery area; wherein the perimeter of the polymer miniature lens is defined by the periphery area; and the polymer miniature lens directly contacts with the substrate surface through the interior area, and wherein the lens forming pattern is a photoresist ring which has an outer boundary, an inner boundary, and an open hole defined by the inner boundary, said periphery area is the area between the outer boundary and the inner boundary, and said interior area is the open hole.
