The photodiodes are formed and arranged in such a manner that in case of incident ultraviolet radiation (26) the electric signal from the photodiode (2) is larger than the further electric signal from the further photodiode (3). In particular, the first photodiode may be more sensitive to ultraviolet radiation than the further photodiode. The electric signal from the photodiode is attenuated by the further electric signal and thus yields an electric signal primarily measuring the incident ultraviolet radiation. The attenuation of the electric signal from the first photodiode may be achieved internally using an integrated circuit (25) or externally using a separate device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultraviolet semiconductor sensor device and method of measuring ultraviolet radiation","description":"A photodiode (2) and a further photodiode (3) are arranged in a substrate (1) at or near a main surface (10).
