ULTRAVIOLET MEASURING DEVICE, PHOTODETECTOR ELEMENT, ULTRAVIOLET DETECTOR, ULTRAVIOLET INDEX CALCULATION DEVICE, AND ELECTRONIC DEVICE INCLUDING SAME

摘要

Disclosed are an ultraviolet measuring device, a photodetector element, an ultraviolet detector, an ultraviolet index calculation device, and an electronic device or portable terminal including the same. An ultraviolet measuring device according to an embodiment of the present invention may comprise: a substrate on which an electrode is formed; a readout integrated circuit (ROIC) unit which is placed within the substrate and electrically connected with the electrode; and an aluminum gallium nitride (AlGaN)-based UVB detection sensor which is placed above the readout integrated circuit unit, electrically connected with the readout integrated circuit unit, and formed on an insulating substrate such as a sapphire substrate, wherein the substrate has a transmissive window made of a transparent material and formed on the surface thereof corresponding to the UVB detection sensor, the readout integrated circuit unit processes an output signal from the UVB detection sensor, and the UVB detection sensor and the readout integrated circuit unit are formed in an integrated structure by bonding.
