Abstract: A bonding pad structure, in particular for a micromechanical sensor, includes a substrate, an electrically insulating sacrificial layer provided on the substrate, a patterned conductor path layer buried in the sacrificial layer, a contact hole provided in the sacrificial layer, and a bonding pad base, composed of an electrically conductive material. The bonding pad base has a first region extending over the sacrificial layer, and a second layer in contact with the conductor path region and extending through the contact hole. A protective layer is provided at least temporarily on the sacrificial layer in a specific region beneath and around the bonding pad base to prevent underetching of the sacrificial layer beneath the bonding pad base during etching of the sacrificial layer in such a way that the substrate and/or the conductor path is exposed.

Abstract: A rate-of-rotation sensor includes a three-layer system. The rate-of-rotation sensor and the conductor traces are patterned out of the third layer. The conductor traces are electrically insulated (isolated) by cutouts from other regions of the third layer and by a second electrically insulating layer from a first layer. Thus, a simple electrical contacting (configuration) is achieved that is patterned out of a three-layer system. Since the same etching process is used for the first and the third layer, an especially efficient manufacturing is possible.
