    摘要: The highly reliable hydrogen impurity testing system includes a sensor unit installed in an atmosphere with highly concentrated hydrogen containing toxic impurities, a heater unit capable of heating the sensor unit, and a system controller controlling the sensor unit and the heater unit. The heater unit includes a semiconductor substrate, an impurity layer of a first conductive type, a metal oxide layer, and a metal electrode layer capable of adsorbing toxic impurities being present on the surface of the metal oxide layer. The system controller detects the concentration of the toxic impurities by measuring the change in work function of the metal electrode layer according to the type and concentration of the toxic impurities, and performs a refreshing operation of desorbing the toxic impurities adsorbed on the metal electrode layer by heating the metal electrode layer with the heater unit based on the result of detection.
