Abstract
A method of manufacturing a photodetector device is provided. The method includes providing a photodetector array comprising an array of photodetectors and a plurality of metal structures arranged between photodetectors of the array of photodetectors, where the plurality of metal structures are arranged in a first pattern; applying an antireflective coating to a surface of a transparent substrate, the antireflective coating being patterned according to a second pattern that matches the first pattern; aligning the transparent substrate over the photodetector array such that the first pattern is aligned with the second pattern; and coupling the transparent substrate to the photodetector array such that the antireflective coating covers the plurality of metal structures.
