Abstract
In a device for the detection of thermal radiation and a method for production of such a device, a stack is formed with a detector support having a detector element for converting the thermal radiation into an electric signal, a circuit support with a read-out circuit for reading out the electrical signal and a cover to shield the detector element. The detector support and the cover are so arranged that a first stack cavity is formed between the detector element and the cover and a second stack cavity is formed between detector support and the circuit support. The first stack cavity and/or the second stack cavity is evacuated and hermetically sealed. In the manufacturing operation, functionalized silicon-substrates are stacked upon one another, firmly bonded together and subsequently sub-divided. Preferably, the detector elements are pyro-electric detector elements. The device finds application in motion detectors, presence reporters and thermal-image cameras.
