Abstract
A fingerprint sensor package with electrostatic discharge on chip mainly includes a substrate, a fingerprint sensor chip, an ESD (electrostatic discharge) bar, and a package body. The fingerprint sensor chip is attached to the substrate. The ESD bar protrudes from the active surface of the fingerprint sensor chip. The package body is formed on the substrate and surrounds the fingerprint sensor chip. The package body is higher than the active surface of the fingerprint sensor chip and partially covers a portion of the active surface so as to connect the ESD bar. Moreover the package body has an opening exposing at least the sensor region of the fingerprint sensor chip on the active surface. The ESD bar is also partially exposed out of the package body along the fringes of the opening to achieve electrostatic discharge on chip.
