Patent ID: 7667282

Claim:
A micromechanical component, comprising: a substrate having a cavity; a membrane provided on the substrate, over the cavity in the substrate, wherein the membrane has a layer system including at least one base layer formed on the substrate for circuit elements; and at least one structured masking layer for defining the circuit elements formed on the base layer; wherein the masking layer is structured in the area of the membrane according to mechanical stresses acting in the cavity in the area of the membrane under vacuum, such that the mechanical stresses are at least partially compensated by the structured masking layer, wherein the masking layer has a compressive stress, and at least one segment of the masking layer is situated in a central area of the membrane where manufacturing-process-related compressive stresses prevail, and wherein the masking layer has a tensile stress, and at least one segment of the masking layer is situated in the edge area of the membrane where manufacturing-process-related tensile stresses prevail.
