Abstract

A fingerprint recognition package may include a circuit board; an image sensor die attached and electrically connected to the circuit board; a light-shielding member applied to the circuit board; and an adhesive member attached to one side of the light-shielding member. The light-shielding member can be cured by being irradiated with ultraviolet rays, and can be thermoset by being irradiated with heat.
