Abstract
An image sensor device is provided. The image sensor device includes a semiconductor substrate and a light sensing region in the semiconductor substrate. The image sensor device also includes a dielectric layer over the semiconductor substrate and a filter partially surrounded by the dielectric layer. The filter has a protruding portion protruding from a bottom surface of the dielectric layer. The image sensor device further includes a shielding layer between the dielectric layer and the semiconductor substrate and surrounding the protruding portion of the filter. In addition, the image sensor device includes a reflective element between the shielding layer and an edge of the light sensing region.
