Abstract
A microcollector for photosensitive devices such as imaging arrays for digital cameras, scanners and other devices, may be formed on a semiconductor structure adjacent to a photosensitive element. The collector may include reflective surfaces arranged about the photosensitive element so as to reflect incident light towards the photosensitive element. The collector may be used in conjunction with a refractive/diffractive microlens to further focus light onto the photosensitive element. As a result, the fill factor of the photosensitive device may be improved, and the signal to noise ratio may also be enhanced.
