Abstract

A manufacturing method for a micromechanical device. In this method, a substrate is prepared with a plating base area to accommodate an anchoring region, and an adhesive layer is formed and structured on the substrate, so that the anchoring region is formed in the plating base area in the form of a quasi-insular region in a recess of the adhesive layer. The quasi-insular region is connected to the adhesive layer outside of the plated based area by at least one thin web. A mask is formed on the adhesive layer and structured so that the anchoring region and an overgrowth region adjacent to the anchoring region remain unmasked. An electroplated layer is deposited on the unmasked anchoring region so that the overgrowth region is overgrown, and the mask and the part of the adhesive layer that has not been overgrown are removed.
