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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device with a sandwich structure for detecting thermal radiation, and method for the production thereof","description":"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 radiatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487257","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
