Abstract
A thermal infrared-detector array has semiconductor-junction elements as detectors. It has high sensitivity and low noise and is fabricated in semiconductor-fabrication process. The semiconductor-junction elements are located in a monocrystalline silicon layer overlying a silicon-oxide layer on a monocrystalline silicon substrate. A signal-output circuit reading out signals from the detector elements includes transistors located on the monocrystalline silicon substrate.
