  • Patent number: 9920993
    Abstract: A photodetector element for receiving radiated light from a surface of a semiconductor wafer loses a detection function because the intensity of the received light exceeds a detection limit while a flash lamp emits light. Measurement is not performed during the above-mentioned period, and the intensity of the radiated light from the surface of the semiconductor wafer is measured after the flash lamp stops emitting light and the photodetector element restores the detection function. Then, the temperature of the surface of the semiconductor wafer heated by irradiation with a flash of light is calculated based on the measured intensity of the radiated light. Accordingly, even in a case where intense irradiation is performed in an extremely short period of time, such as flash irradiation, the flash of light does not act as ambient light, which enables to obtain the surface temperature of the semiconductor wafer.

  • Patent number: 9295107
    Abstract: A capacitor, a coil, a flash lamp, and a switching element such as an IGBT are connected in series. A controller outputs a pulse signal to the gate of the switching element. A waveform setter sets the waveform of the pulse signal, based on the contents of input from an input unit. With electrical charge accumulated in the capacitor, a pulse signal is output to the gate of the switching element so that the flash lamp emits light intermittently. A change in the waveform of the pulse signal applied to the switching element will change the waveform of current flowing through the flash lamp and, accordingly, the form of light emission, thereby resulting in a change in the temperature profile for a semiconductor wafer.

  • Patent number: 9180550
    Abstract: The temperature of a semiconductor wafer is raised by light irradiation heating performed by halogen lamps. An infrared ray emitted from the semiconductor wafer whose temperature has been raised transmits through an infrared-transparent window made of silicon, and then is detected by an infrared camera. The infrared camera two-dimensionally detects the temperature of an entire surface of the semiconductor wafer. Based on a result of the detection obtained by the infrared camera, a temperature drop region having a relatively low temperature among the region of the semiconductor wafer is irradiated with laser light emitted from a laser light emission part. Accordingly, without rotating the semiconductor wafer, a temperature distribution can be made uniform with a high accuracy throughout the entire surface of the semiconductor wafer.

  • Patent number: 8901460
    Abstract: After flash irradiation on a semiconductor wafer is started and then the temperatures of front and back surfaces of the semiconductor wafer become equal to each other, the temperature of the back surface of the semiconductor wafer, which has a known emissivity, is measured with a radiation thermometer. The emissivity of the front surface of the semiconductor wafer is calculated based on the intensity of radiated light from a black body having an equal temperature to the temperature of the back surface thereof, and the intensity of radiated light actually radiated from the front surface of the semiconductor wafer. Then, the temperature of the front surface of the semiconductor wafer heated by the flash irradiation is calculated based on the calculated emissivity and the intensity of the radiated light from the front surface of the semiconductor wafer that has been measured after the flash irradiation is started.

  • Patent number: 8891948
    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.

  • Patent number: 8624165
    Abstract: When a semiconductor wafer is preheated by halogen lamps, the temperature of a peripheral portion of the semiconductor wafer is lower than that of a central portion thereof. A laser light emitting part disposed immediately under the center of the semiconductor wafer is rotated about the center line of the semiconductor wafer, while laser light is directed from the laser light emitting part toward the peripheral portion of the semiconductor wafer. Thus, the irradiation spot of the laser light exiting the laser light emitting part swirls around along the peripheral portion of the back surface of the semiconductor wafer so as to draw a circular trajectory. As a result, the entire peripheral portion of the semiconductor wafer at a relatively low temperature is uniformly heated. This achieves a uniform in-plane temperature distribution of the semiconductor wafer.
