The elongate sensor element () is electrically connected within the second subframe volume ().

Sensor device and method of manufacture

A piezo-resistor sensor includes a diffusion of a first conductivity type in a well of an opposite second type, contacts with islands in the diffusion, interconnects with the contacts, and a shield covers the diffusion between the contacts and extends over side walls of the diffusion between the contacts. Each interconnect covers the diffusion at the corresponding contact and extends over edges of the diffusion, and each island is at a side covered by its interconnect. A guard ring of the second type is around the diffusion. The shield covers the well between the diffusion and the ring and the edge of the ring facing the diffusion. If a gap between the shield and the interconnect is present, the ring bridges this gap, and/or the edges of the diffusion are completely covered by the combination of the shield and the interconnects.
