Abstract:
A packaging structure and a packaging method are provided. The packaging structure includes: a chip unit, where a first surface of the chip unit includes a sensing region; and an upper cover plate, where a first surface of the upper cover plate is provided with a support structure, the upper cover plate covers the first surface of the chip unit, the support structure is located between the upper cover plate and the chip unit, the sensing region is located in a cavity enclosed by the support structure and the first surface of the chip unit, and the upper cover plate has a preset thickness, so that light reflected by a sidewall of the upper cover plate is not directly incident on the sensing region.

Claim (Index 14):
The packaging method according to  claim 8 , wherein the chip unit further comprises a contact pad located outside the sensing region, and after attaching the first surface of the cover substrate with the first surface of the wafer to be packaged, the packaging method further comprises:\n thinning the wafer to be packaged from a second surface of the wafer to be packaged opposite to the first surface of the wafer to be packaged; etching the wafer to be packaged from the second surface of the wafer to be packaged, to form through holes through which the contact pads of the chip units are exposed; forming an insulation layer on the second surface of the wafer to be packaged and surfaces of side walls of the through holes; forming a metal layer on a surface of the insulation layer, wherein the metal layer is connected with the contact pads; forming a solder mask on a surface of the metal layer and the surface of the insulation layer, wherein the solder mask is provided with openings through which a portion of the surface of the metal layer is exposed; and forming protrusions for external connection on a surface of the solder mask, wherein the openings are filled by the protrusions for external connection.
