Abstract
In a photosensitive chip suitable for full-color imaging, separate photosites on the chip correspond to different primary colors in an original image. Each primary-color photosite is filtered with a polyimide doped to a particular primary color. The red-filtering layer and the blue-filtering layer are left on the non-photosensitive portions of the main surface of the chip, and together serve as a non-reflective area which prevents stray reflections from the chip. The chip is further provided with a base layer of infrared-filtering polyimide.
