Abstract
Provided is an image sensor and a method of forming the same. The image sensor includes a first substrate having a first surface and a second surface opposite to each other; a plurality of photodetectors, disposed in the first substrate; and a plurality of color filters, disposed on the second surface of the first substrate and respectively corresponding to the plurality of photodetectors. The plurality of color filters are composed of a plurality of PIN diodes, and the plurality of PIN diodes are configured to absorb light of different wavelength ranges by applying different bias voltages.
