Abstract:
A packaging method and a package structure for a fingerprint recognition chip and a drive chip are provided. The packaging method is a wafer-level packaging method. According to the method, a blind hole is formed on the back surface of a wafer and the drive chip is secured in the blind hole, then the wafer is cut to obtain a package structure for the fingerprint recognition chip and the drive chip. In this way, the drive chip is packaged in the back surface of the wafer-level fingerprint recognition chip, thereby reducing the complexity of the package process. In addition, the size of the package structure is close to the size of the single fingerprint recognition chip, thereby greatly reducing the size of the package structure and improving the integration of the package structure.

Claim (Index 14):
A package structure for a fingerprint recognition chip and a drive chip, comprising:\n a fingerprint recognition chip, having a first surface and a second surface facing away from the first surface; a drive chip, having a first surface and a second surface facing away from the first surface, wherein the first surface of the drive chip is provided with a drive circuit and a second contact pad; and a blind hole arranged on the second surface of the fingerprint recognition chip, wherein the drive chip is secured in the blind hole, and the first surface of the drive chip is flush with the second surface of the fingerprint recognition chip.
