Abstract
An image sensor device is disclosed. The image sensor device includes a semiconductor substrate having a first pixel region and a second pixel region. A first photo-conversion device is disposed within the first pixel region of the semiconductor substrate to receive a first light source. A second photo-conversion device is disposed within the second pixel region of the semiconductor substrate to receive a second light source different from the first light source. The surface of the semiconductor substrate corresponding to the first photo-conversion device and the second photo-conversion device has a first microstructure and a second microstructure, respectively, permitting a reflectivity of the first pixel region with respect to the first light source to be lower than a reflectivity of the second pixel region with respect to the first light source. The invention also discloses a fabrication method of the image sensor device.
