Abstract:
A radiation-sensing device, comprising:first and second semiconductor substrates respectively formed of first and second semiconductor materials that are different from each other;a first detector array formed of said first semiconductor material in said first semiconductor substrate and configured to have detectors to detect first radiation in a visible spectral range to produce first electrical signals indicating said first radiation;a first readout circuit formed in said first semiconductor substrate relative to said first detector array and connected to receive said first electrical signals;a second detector array formed of said second semiconductor material in said second semiconductor substrate and configured to have detectors to detect second radiation in an infrared spectral range to produce second electrical signals indicating said second radiation;a second readout circuit coupled to said second detector array to receive said second electrical signals,wherein said first semiconductor substrate and said second semiconductor substrate are physically bonded together to form an integrated module.
