Abstract
An optical sensor device and a method for forming the same are provided, including forming a curable transparent material on a substrate, wherein the substrate has a plurality of optical sensor units therein; providing a transparent template, which has a plurality of concaves; imprinting the curable transparent material with the transparent template to form a plurality of convexes corresponding to the plurality of concaves; and curing the curable transparent material to form a transparent layer having a micro-lens array. The step of curing the curable transparent material includes adhering the transparent template to the curable transparent material to act as a cover plate for the optical sensor device.
