SINGLE CHIP IMAGE SENSOR WITH BOTH VISIBLE LIGHT IMAGE AND ULTRAVIOLET LIGHT DETECTION ABILITY AND THE METHODS TO IMPLEMENT THE SAME

摘要

The present invention relates to a single chip image sensor with both visible light image and ultraviolet light detection ability and methods to implement the single chip image sensor. In an embodiment, a single chip image sensor may comprise a first plurality of sensor cells provided on a substrate, the first plurality of sensor cells each including a photo detector sensitive to visible light, and a UV coating layer provided for the first plurality of sensor cells to convert incident UV light to visible light.
