Abstract
An image sensor device includes nanostructures for improving light absorption efficiency. The image sensor device includes a substrate, a light absorption region, and a nanostructure array. The light absorption region is over the substrate. The nanostructure array us over the light absorption region. The nanostructure array includes a plurality of nanostructures repeatedly arranged from a top view.
