Abstract
A micromechanical component, in particular a pressure sensor, including a substrate that has a membrane region, a surrounding region of the membrane region, at least one measuring resistance provided in the membrane region and modifiable by deformation of the membrane region, and a corresponding evaluation circuit provided in the surrounding region. An interference effect on the measuring resistance is producible by way of a deformation of parts, in particular conductor paths, of the evaluation circuit relative to the substrate. The invention also creates a corresponding equalization method on a test chip or as an individual final equalization.
