Abstract:
1. A method for fabricating a micro-lens, comprising: forming a plurality of micro-cavities in a substrate; filling lens material into each of the micro-cavities; heating the lens material in the micro-cavities; and curing the lens material in the micro-cavities to form a plurality of micro-lenses in the substrate, wherein the step of forming the plurality of micro-cavities in a substrate further includes forming a negative photoresist layer on the substrate and performing photolithography on the negative photoresist layer by using a photomask, and the step of filling the lens material into each of the micro-cavities further includes forming a positive photoresist layer on the negative photoresist layer, and applying photolithography to the positive photoresist layer by using the photomask to form the lens material in each of the micro-lenses.
