<p>Provided is a method of forming an image sensor comprising the steps of defining pixel areas and each of these areas includes at least a MOS buffer transistor and a second MOS circuitry and a photosensitive area with a photosensitive element therein, whereby the photosensitive element takes less from the left amount of space and optimizing the geometry such that diffused charges in the substrate are collected effectively by the photosensitive element.</p> |
