Fingerprint sensor module comprising a fingerprint sensor device and a substrate connected to the sensor device

A fingerprint sensor module comprising:

• a rigid fingerprint sensor device comprising a plurality of sensing elements for acquiring an image of a finger placed on a sensing surface of the sensor module, the sensor device comprising at least one trench at an edge of the fingerprint sensor device, the trench comprising electrically conductive connection pads for connecting the sensor device to external circuitry;
• and
• a substrate comprising an electrically conductive trace and an electric component arranged on the substrate and in electrical contact with the conductive trace, wherein a first side of the substrate is electrically and mechanically connected to the edge trench such that an electrical connection is formed between the sensor device and the electrical component of the substrate via the conductive trace, the substrate comprising a flexible curved portion adjacent to the trench of the fingerprint sensor device, wherein the substrate is bent and folded in under the fingerprint sensor device.
