Abstract
A biometric sensor device, such as a fingerprint sensor, comprises a substrate to which is mounted a die on which is formed a sensor array and at least one conductive bezel. The die and the bezel are encased in a unitary encapsulation structure to protect those elements from mechanical, electrical, and environmental damage, yet with a portion of the sensor array and the bezel exposed or at most thinly covered by the encapsulation or other coating material structure.
