  • Publication number: 20100163759
    Abstract: An embodiment relates to a sensor integrated on a semiconductor substrate and comprising at least one first and second photodiode including at least one first and one second p-n junction made in such a semiconductor substrate as well as at least one first and one second antireflection coating made on top of such a first and second photodiode. At least one antireflection coating of such a first and second photodiode comprises at least one first and one second different antireflection layer to make a double layer antireflection coating suitable for obtaining for the corresponding photodiode a responsivity peak at a predetermined wavelength of an optical signal incident on the sensor. An embodiment also refers to an integration process of such a sensor, as well as to an ambient light sensor made with such a sensor.
