Patent ID: 7795656

Claim:
An image sensor device including an optical black pixel region and an active pixel region, the device comprising: a light receiving unit including a plurality of light sensitive semiconductor devices that are configured to detect light incident thereon; a pixel metal wire layer including a transparent material on the light receiving unit and including a plurality of metal wires therein; a filter unit on the pixel metal wire layer, wherein the filter unit comprises a plurality of filters that are configured to transmit light according to a wavelength thereof, the filter unit including blue color filters in the optical black pixel region of the image sensor device; and a light blocking layer in the optical black pixel region between the filter unit and the light receiving unit, wherein the light blocking layer is configured to block light that has passed through the filter unit; wherein the light blocking layer in the optical black pixel region comprises silicon and has an absorption and/or reflection property with respect to light that has passed through the filter unit.
