Patent ID: 8564078

Claim:
A micromechanical component, comprising: a substrate having a first side and a second side; at least one trench structure, wherein a filler material substantially fills up the at least one trench structure; and an insulating layer on the first side of the substrate; wherein a filler layer of a filler material is applied from the first side of the substrate into the at least one trench structure, wherein there is a planarization within a plane of one of the filler layer and the insulating layer, wherein there is a further planarization of the substrate from a second side of the substrate, wherein at least one additional layer is applied onto subregions of the second side of the substrate, the at least one additional layer being in contact with the filler material in each of the at least one trench structure, and wherein the at least one trench structure is substantially equal to a thickness of the micromechanical component, so that back-side contacting of the micromechanical component on the second side of the substrate is possible.
