An infrared light sensor for an infrared light detector (), including a substrate membrane section () and at least two sensor chips (to), which are fastened next to each other on the substrate membrane section () and each comprise a layer element () which is produced from pyroelectrically sensitive material and is electrically contacted by a base electrode () and a head electrode () and is arranged in such that there is a voltage difference in each case between the head electrode () and the base electrode () of each layer element () when the layer elements () are irradiated with infrared light; and a coupling line (to) in each case for two adjacently arranged sensor chips (to), the coupling line coupling the head electrode () of the one sensor chip (to) and the base electrode () of the other sensor chip (to) to each other in an electrically conductive manner so that the layer elements () of the sensor chips (to) are connected in a series circuit, which has one of the base electrodes () at one end thereof and one of the head electrodes () at the other end thereof, at which a total voltage difference of the series circuit can be tapped as the sum of the individual voltage differences of the layer elements ().

Infrared light sensor having a high signal voltage and a high signal/noise ratio

An apparatus for detecting radiation has a substrate, a protective housing fitting on the substrate, which has an electrically conductive material and a top facing away from the substrate, and that has an aperture therein. A stack is fitted on the substrate inside the protective housing and includes at least one detector substrate having at least one thermal detector element thereon that converts incoming thermal radiation into an electrical signal, at least one circuit carrier having at least one read circuit for reading out the electrical signal, and at least one cover that covers the detector element. The detector substrate is located between the circuit substrate and the cover. The detector substrate and the cover are arranged on each other such that the detector element of the detector substrate and the cover have at least one first stack cavity of the stack therebetween, the stack cavity being defined by the detector support and the cover. The circuit substrate and the detector substrate are arranged on each other such that the detector substrate and the circuit substrate have at least one second stack cavity therebetween, the second stack cavity being defined by the circuit substrate and the detector substrate. At least one of the first stack cavity and the second stack cavity is evacuated. The stack top that faces the substrate is accessible from outside of the protective housing.
