FINGERPRINT SENSOR MODULE, PORTABLE ELECTRONIC DEVICE HAVING THE SAME, AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a fingerprint sensor module with excellent sensing sensitivity, a mobile electronic device including the fingerprint sensor module, and a manufacturing method thereof. The fingerprint sensor module according to an embodiment of the present invention includes; a fingerprint sensor; and a bracket which mounts the fingerprint sensor. The fingerprint sensor includes: a sensing unit which is formed on a substrate to receive the difference between electric signals of the recessed and protruding ribs of a fingerprint on top of the substrate; and a sensor circuit unit sensing and processing the fingerprint image. The bracket includes a cover layer formed to cover the upper surface of the sensing unit, and the cover layer comprises a ferroelectric.
