Abstract
The present application provides a fingerprint identification module and a package structure of a fingerprint identification chip. The fingerprint identification module includes: a fingerprint identification chip and a package structure for packaging the fingerprint identification chip. The package structure leaves a fingerprint sensing region of the fingerprint identification chip exposed, an upper surface of a film layer of the fingerprint sensing region is provided with a protection layer with a predetermined thickness. The protection layer is exposed in the fingerprint sensing region outside the package structure and causes the fingerprint identification chip to have a predefined fingerprint identification distance. The fingerprint identification module and the package structure with a protection layer arranged on the upper surface of the fingerprint identification chip provide sufficient protections for fabrication processes such as downstream module assembly, while ensuring that the fingerprint identification chip has a predefined fingerprint identification distance.
