Claim:
1. A micromechanical sensor device, comprising: an ASIC substrate having a first front side and a first rear side; a rewiring element formed on the first front side and including multiple stacked conductor levels and insulating layers; a MEMS substrate having a second front side and a second rear side; a first micromechanical functional layer formed on top of the second front side; a second micromechanical functional layer formed on top of the first micromechanical functional layer and connected to the rewiring element via a bond connection; a movable sensor structure formed in the second micromechanical functional layer and anchored on one side on the MEMS substrate via a first anchoring area formed in the second micromechanical functional layer; an electrical connecting element which is formed in a second anchoring area of the second micromechanical functional layer and anchored on one side of the ASIC substrate via a contact area of the bond connection; and a spring element formed in the second micromechanical functional layer and elastically connecting the first anchoring area and the second anchoring area to one another.
