  • Stacked multi-spectral image sensor
    Publication number: 20240079440
    Abstract: A multispectral sensing device includes a first die, including silicon, which is patterned to define a first array of sensor elements, which output first electrical signals in response to optical radiation that is incident on the device in a band of wavelengths less than 1000 nm that is incident on the front side of the first die. A second die has its first side bonded to the back side of the first die and includes a photosensitive material and is patterned to define a second array of sensor elements, which output second electrical signals in response to the optical radiation that is incident on the device in a second band of wavelengths greater than 1000 nm that passes through the first die and is incident on the first side of the second die. Readout circuitry reads the first electrical signals and the second electrical signals serially out of the device.
