1. A method for fabricating a micromechanical component, comprising the following steps:

  • producing a first layer composite having a first substrate and a first insulation layer, which covers at least one part of a first surface of the first substrate, wherein first depressions are produced in the first surface of the first substrate,producing a second layer composite having a second substrate and a second insulation layer, which covers at least one part of a surface of the second substrate,after forming the first depressions, applying an at least partly conductive structure layer to the first layer composite, wherein the structure layer is formed on the insulation layer and over portions of the first substrate, in which the first depressions are produced,applying the second composite to the structure layer in such a way that the second insulation layer adjoins the structure layer,wherein the first and second layer composites and also the structure layer are configured in such a way that at least one part of the structure layer which comprises an active area comprising an active structure of the component is sealed by the first and second layer composites,after applying the second composite to the structure layer, forming contact holes within the first substrate for making contact with conductive regions of the structure layer,wherein lateral positions of the contact holes at least partly overlap with lateral positions of the first depressions, andwherein the lateral positions of the first depressions at least partly overlap with lateral positions of the conductive regions of the structure layer to be contacted through the contact holes.
