Abstract
A method of forming a wavelength-selective optical low-pass antiliasing filter for use with an optical imaging system of a solid-state color imager or the like is disclosed. The method includes coating a transparent glass wafer with a layer of transparent photopatternable organic polymer material having a thickness that is equal to the thickness of randomly placed transparent low-pass antiliasing filter spots, exposing the transparent photopatternable layer in areas to form a pattern of randomly placed spots in unexposed areas that correspond to the optical low-pass antiliasing filter, and developing the exposed transparent photopatternable layer to remove the exposed regions corresponding to pattern of randomly placed transparent low-pass antiliasing filter spots.
