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 structure, where a first surface of the upper cover plate structure is provided with a groove structure, the first surface of the chip unit is attached with the first surface of the upper cover plate structure, the sensing region is located within a cavity surrounded by the groove structure and the first surface of the chip unit, the upper cover plate structure further includes a second surface opposite to the first surface, and an area of the second surface of the upper cover plate structure is less than an area of the first surface of the upper cover plate structure.

Claim (Index 15):
The packaging method according to  claim 9 , 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 a through hole by which the contact pad of the chip unit is exposed; forming an insulation layer on the second surface of the wafer to be packaged and a surface of a side wall of the through hole; forming a metal layer on a surface of the insulation layer, wherein the metal layer is connected with the contact pad; 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 an opening by which a portion of the surface of the metal layer is exposed; and forming a protrusion for external connection on a surface of the solder mask, wherein the opening is filled by the protrusion for external connection.
