Abstract:
A semiconductor device for flame detection, including: a semiconductor body having a first conductivity type conductivity, delimited by a front surface and forming a cathode region; an anode region having a second conductivity type conductivity, which extends within the semiconductor body, starting from the front surface, and forms, together with the cathode region, the junction of a photodiode that detect ultraviolet radiation emitted by the flames; a supporting dielectric region; and a sensitive region, which is arranged on the supporting dielectric region and varies its own resistance as a function of the infrared radiation emitted by the flames.
