  • Publication number: 20240429257
    Abstract: An image sensing device includes a germanium sensor within a semiconductor body and a metalens formed in the back side of the semiconductor body. The metalens is structured to focus infrared light on the germanium sensor and may have a lower profile than an equivalent microlens. Optionally, the metalens is combined with a microlens to achieve a desired focal length. The metalens, or the metalens in combination with a microlens, overcomes a manufacturing process limitation on the focal length of the microlens, which in turn eliminates the need for, or reduces the thickness of, a spacer between the microlens and the germanium sensor. Eliminating the spacer or reducing its thickness improves the angular response of the image sensing device.
