Abstract
A sensor device comprising a substrate, the substrate comprising one or more magnetic sensor elements; a first elastomeric material on top of the one or more magnetic sensor elements; a magnetic layer comprising a soft magnetic metal alloy deposited by electroplating or by sputtering on top of the first elastomeric material; and optionally a second elastomeric material on top of the magnetic layer. The substrate may be a CMOS device with IMC encapsulated between two polyimide layers. The magnetic material may be annealed at 250° C. to 295° C. using a constant or rotating magnetic field having a strength in the range from 100 to 300 mTesla. The soft magnetic alloy is arranged as Integrated Magnetic Concentrator (IMC).
