Abstract: The present disclosure relates to a fingerprint sensor device. The device comprises a sensor having a sensitive active region that is electrically connected to a substrate. The device further includes a first resin bump positioned proximate to the sensitive active region. The first resin bump forms a finger guide that positions the finger over the sensitive active region when the finger slides in contact with the first resin bump.

Abstract: An embodiment of the present invention related to fingerprint sensors is described. The sensor comprises an integrated-circuit chip having a sensitive surface, a substrate provided with electrical connections and wire-bonding wires connecting the chip to the electrical connections. The sensor further includes a molded protective resin at least partly covering the substrate and the chip and completely encapsulating the wire-bonding wires. The resin forms, on at least one side of the chip and at most three sides, a bump rising to at least 500 microns above the sensitive surface, this bump encapsulating the wire-bonding wires and constituting a guide for a finger, the fingerprint of which it is desired to detect.
