Abstract:
1. A microstructured sensor, comprising: one measurement chip in which there is formed a first measurement area having a first measurement structure and at least one second measurement area having a second measurement structure, the measurement areas being offset to one another in a lateral direction; one cap chip that is made of silicon and is fastened in vacuum-tight fashion to the measurement chip in a connecting area; one intermediate space, formed between the measurement chip and the cap chip, that is sealed outwardly by the connecting area and in which the measurement areas are situated; and at least one contact area, formed on the measurement chip, and left exposed by the cap chip, for the contacting of the measurement chip, wherein between the measurement areas there is formed a wafer bond support point in which the cap chip is fastened on the measurement chip; wherein the microstructured sensor is a gas sensor for measuring a gas concentration, the first measurement area is provided for the detection of incident infrared radiation in a first wavelength range, the second measurement area is provided for the measurement of infrared radiation in a second wavelength range, and the cap chip is transparent to the infrared radiation that is to be measured.
