Patent ID: 7273764

Claim:
A method for producing a sensor with at least one silicon-base micromechanical structure integrated with a sensor chamber of a foundation wafer and a covering that covers the foundation wafer at least in the region of the sensor chamber, the method comprising the steps of establishing the structure ( 26 ) in the foundation wafer ( 11 ); filling at least the sensor chamber ( 28 ) which is present in the foundation wafer ( 11 ) after the establishment of the structure ( 26 ) with an oxide; covering the sensor chamber ( 28 ) by a first layer ( 32 ) which is a deposition layer selected from the group consisting of a layer that is transparent to an etching medium and reaction products and a layer which is retroactively made transparent; removing the oxide ( 30 ) in the sensor chamber ( 28 ) through the deposition layer ( 32 ) with the etching medium; and applying a second layer ( 34 ) which is a sealing layer, to the deposition layer ( 32 ) and hermetically sealing off the sensor chamber ( 28 ).
