IMAGE SENSOR WITH FOCUSING INTERCONNECTION |
摘要 |
An image sensor includes a photosensitive region formed in a substrate of an integrated circuit. The substrate has a first layer of metal formed over the surface of the substrate so the first layer of metal defines a first aperture that has a first aperture width through with the incident light passes before illuminating the photosensitive region. The first aperture width is equal to or less than the width of the photosensitive region below the first aperture. The substrate also has a second layer of metal formed over the first layer of metal. The second aperture has a second aperture width that is wider than the first aperture width. The first and second apertures focus the incident light onto the photosensitive region.
