Beschreibung
Zusammenfassung:	An infrared sensor device includes a semiconductor substrate, at least one sensor element that is micromechanically formed in the semiconductor substrate, and at least one calibration element, which is micromechanically formed in the semiconductor substrate, for the sensor element. An absorber material is arranged on the semiconductor substrate in the area of the sensor element and the calibration element. One cavern each is formed in the semiconductor substrate substantially below the sensor element and substantially below the calibration element. The sensor element and the calibration element are thermally and electrically isolated from the rest of the semiconductor substrate by the caverns. The infrared sensor device has high sensitivity, calibration functionality for the sensor element, and a high signal-to-noise ratio.
