Abstract
Systems and methods are disclosed for fabricating a device by forming a photosensitive area on a wafer; forming a control circuit adjacent the photosensitive area; and coating the photosensitive area with one or more film layers to form an optical filter. The filter provides a reduced leakage of an undesired wavelength onto the photosensitive area.
