Abstract:
A chip package and a chip packaging method are provided. The package includes: a chip to be packaged, a reinforcing layer and solder bumps. The chip to be packaged includes a first surface and a second surface opposite to each other, the first surface includes a sensing region and first contact pads, and the first contact pads are electrically coupled to the sensing region. The reinforcing layer covers the first surface of the chip to be packaged. The solder bumps are provided on the second surface of the chip to be packaged. The solder bump is electrically connected to the first contact pad and is configured to electrically connect with an external circuit.

Claim (Index 20):
The chip packaging method according to  claim 15 , wherein the forming the solder bump on the other surface of the wafer comprises:\n forming an inclined cutting plane on a sidewall of the chip to be packaged, wherein the second surface is smaller than the first surface due to the inclined cutting plane, to expose the first contact pads; forming an insulating layer covering the inclined cutting plane and the second surface of the chip to be packaged, wherein the insulating layer is configured to expose the first contact pads; forming a rewiring layer covering the first contact pads and the insulating layer; and forming the solder bumps on a surface of the rewiring layer, wherein the solder bumps are provided opposite to the sensing region of the chip to be packaged.
