Patent ID: 7563652

Claim:
A method for encapsulating sensor chips, comprising steps of: providing a sensor chip having an active surface, a back surface opposite to the active surface, and a plurality of side surfaces defined between the active surface and the back surface, wherein the active surface has a plurality of bonding pads formed thereon and includes a sensor region; forming a protective layer on the active surface of the sensor chip, wherein the protective layer at least covers the sensor region; attaching the sensor chip to a temporary carrier, wherein the active surface of the sensor chip faces to the temporary carrier, and is attached to the temporary carrier via the protective layer; forming an encapsulant on the temporary carrier, wherein the encapsulant covers the back surface and the side surfaces of the sensor chip; removing the temporary carrier; and forming a plurality of electrically connecting components in the encapsulant, wherein the electrically connecting components are electrically connected to the bonding pads of the sensor chip.
