Abstract:
A method of producing a hybrid high-temperature detector comprisinga high-temperature sensor chip comprising a high-temperature measuring film, a first connection made of a high-temperature-stable material and a second connection made of a high-temperature-stable material, the first and second connections being connected to the high-temperature measuring film; the method comprising: a) arranging the high-temperature sensor chip in a through-hole of a first ceramic substrate, the through-hole being arranged adjacent to a first end of the first ceramic substrate; b) fusing the first ceramic substrate with a second ceramic substrate so that a conductor track arranged on the second ceramic substrate is connected to the first connection of the high-temperature sensor chip at a first end of the second ceramic substrate, the conductor track extending to a second end of the second ceramic substrate; c) fusing the first ceramic substrate to a third ceramic substrate so that a conductor track arranged on the third ceramic substrate is connected to the second connection of the high-temperature sensor chip at a first end of the third ceramic substrate, wherein the fusing of the ceramic substrates seals the sensor chip from the atmosphere; and d) applying a first connecting area to the second elongate ceramic substrate and a second connecting area to a third elongate ceramic substrate for connecting electrical leads via a non-high-temperature-stable material so as to tap a signal produce by the high-temperature sensor chip.
