    Abstract: A photodiode excellent in responsivity receives flashes of light emitted from flash lamps in the process of heating a semiconductor wafer by irradiation with flashes of light, and the waveform of the intensity of the flashes of light versus time is acquired using voltage data obtained from an output from the photodiode. Then, a temperature calculating part performs a heat conduction simulation using the acquired data to calculate the temperature of the semiconductor wafer irradiated with the flashes of light from the flash lamps. The temperature of the semiconductor wafer is computed using data corresponding to the intensity of the flashes of light obtained from the output from the photodiode. This allows the determination of the surface temperature of the semiconductor wafer irradiated with the flashes of light, irrespective of the waveform of the emission intensity of the flash lamps.

  • Publication number: 20140284483
    Abstract: There is provided a high responsivity device for thermal sensing in a Terahertz (THz) radiation detector. A load impedance connected to an antenna heats up due to the incident THz radiation received by the antenna. The heat generated by the load impedance is sensed by a thermal sensor such as a transistor. To increase the responsivity of the sense device without increasing the thermal mass, the device is located underneath a straight portion of an antenna arm. The transistor runs substantially the entire length of the antenna arm alleviating the problem caused by placing large devices on the side of the antenna and the resulting large additional thermal mass that must be heated. This boosts the responsivity of the pixel while retaining an acceptable level of noise and demanding a dramatically smaller increase in the thermal time constant.

  • Patent number: 8834019
    Abstract: A non-contact infrared (IR) thermometer for measuring temperature from the surface of an object includes an IR radiation sensor attached to a heating element and a thermal shield having an interior surface positioned within the sensor's field of view that has a high emissivity. An electronic circuit controlling the heating element maintains the temperatures of the sensor and shield substantially close to an anticipated surface temperature of the object. The IR radiation sensor is further thermally coupled to a reference temperature sensor. An optical system positioned in front of the shield focuses thermal radiation from the object on the surface of the sensor, while the shield prevents stray radiation from reaching the sensor. Signals from the IR and reference sensors are used to calculate the object's surface temperature.
