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 7):
The packaging structure according to  claim 1 , wherein the chip unit further comprises:\n a contact pad located outside the sensing region; a through hole extending through the chip unit from a second surface of the chip unit opposite to the first surface of the chip unit, wherein the contact pad is exposed through the through hole; an insulation layer covering the second surface of the chip unit and a surface of a sidewall of the through hole; a metal layer located on a surface of the insulation layer and electrically connected to the contact pad; a solder mask located on a surface of the metal layer and the surface of the insulation layer, wherein the solder mask is provided with an opening through which a portion of the metal layer is exposed; and a protrusion for external connection by which the opening is filled, wherein the protrusion for external connection is exposed outside a surface of the solder mask.
