Patent ID: 7187067

Claim:
A sensor chip packaging structure comprising: a chip carrier having a front surface and a corresponding back surface, wherein the chip carrier has at least a contact pad on the front surface; a semiconductor chip having an active surface and a corresponding back surface, wherein the active surface comprises a sensing region, and the semiconductor chip is attached to the front surface of the chip carrier; at least a bonding pad and at least a grounding pad disposed on the active surface; a metal dam bar electrically coupled to the grounding pad, protruding from the active surface and separating the sensing region and the bonding pad for removing electrostatic discharges; at least a connective device electrically connecting the bonding pad to the contact pad of the chip carrier; and a molding compound disposed on the chip carrier and surrounding the semiconductor chip, wherein the molding compound partially encloses the active surface of the semiconductor chip along the metal dam bar for exposing the sensing region.
