BIO-SENSING DEVICE

Abstract: a bio-sensing device is provided, which includes a carrier substrate, a light source disposed on the carrier substrate, a photodiode sensor disposed on the carrier substrate and laterally spaced apart from the light source, a light-blocking wall disposed on the carrier substrate and located between the light source and the photodiode sensor, a cover glass, a dual-band filter coated on a front surface of the cover glass, a first optical adhesive formed on a back surface of the cover glass, and a second optical adhesive covering the carrier substrate, the light source, the photodiode sensor and the light-blocking wall, and being used to be bonded with the first optical adhesive. the first optical adhesive has been cured when the second optical adhesive is bonded with the first optical adhesive, and the second optical adhesive is cured by irradiation with ultraviolet light after being in contact with the first optical adhesive.
