  • Patent number: 11257858
    Abstract: A method of fabricating a sensor device including at least the following steps is provided. An optical film stack is formed on a sensor substrate, wherein the sensor substrate includes a sensor region and a pad region beside the sensor region, and the optical film stack covers the sensor region while exposes the pad region. A releasing pattern is formed on the pad region. A lens material layer is formed on the sensor substrate to cover the releasing pattern and the optical film stack. The releasing pattern is removed from the sensor substrate to expose the pad region by patterning the lens material layer to form a lens on the optical film stack.
