Abstract
An image sensor device and a manufacturing method for forming an image sensor device are provided. The image sensor device includes a semiconductor substrate having an array region and a periphery region. The image sensor device also includes a light sensing region in the array region of the semiconductor substrate. The image sensor device further includes a dielectric structure over the array region and the periphery region, and the dielectric structure has a substantially planar top surface. In addition, the image sensor device includes a recess in the dielectric structure and substantially aligned with the light sensing region. The image sensor device also includes a filter in the recess and a light blocking grid in the dielectric structure and surrounding a portion of the filter.
