    摘要: A photo sensor comprises a semiconductor substrate, a bipolar photo transistor having an emitter region, a base region and a collector region which is formed in the surface region of the semiconductor substrate, a silicon dioxide formed on the bipolar phototransistor, and a film having a smaller diffusion coefficient of hydrogen than the silicon dioxide formed all over the silicon dioxide.
