Abstract
A thin-film fingerprint sensor package primarily comprises a fingerprint sensor chip, a plurality of bumps, a wiring film, an encapsulant and a metal base to mechanically hold the fingerprint sensor chip. A sensing area is formed on the active surface of the fingerprint sensor chip. The bumps are disposed on the active surface. The wiring film has an opening to expose the sensing area and comprises a plurality of leads bonded to the bumps. The wiring film further has a ground lead electrically connecting the fingerprint sensor chip to the metal base. Therefore, the fingerprint sensor package can provide ESD protection during fingerprint recognition to avoid the damage of the fingerprint sensor chip.
