A light absorption ring is provided so as to be close to a peripheral portion of the semiconductor wafer held by the susceptor. The light absorption ring absorbs infrared light and transmits visible light through itself. During preliminary heating, the light absorption ring absorbs light emitted from the continuous lighting lamp to be increased in temperature so that heat radiated from the peripheral portion of the wafer is compensated to cause in-plane temperature distribution of the semiconductor wafer to be uniform. Meanwhile, the flash of light is transmitted through the light absorption ring, so that the light absorption ring is prevented from being damaged by the irradiation of the flash of light.

  • Patent number: 10295154
    Abstract: Broadband solid state light sources include remote phosphor LED(s), short-wavelength direct emitting LED(s), and long-wavelength direct emitting LED(s). A diffuse or clear cover member covers these LEDs. Each remote phosphor LED includes an LED, a phosphor layer, and a dichroic reflector. The light sources can provide a broadband output light over a wide color range, and can do so efficiently while energizing a high percentage or proportion of the total number of LEDs in the system. The broadband output may for example exhibit a color difference of at least 0.2 in CIE chromaticity units, and/or a correlated color temperature difference of at least 4000 or 5000 Kelvin, while energizing more than half, or at least 60%, or at least 70%, of the total number of LEDs. Numbers of LEDs can be replaced with effective numbers of LEDs if LEDs of substantially different sizes are included in the light source.

  • Patent number: 10180397
    Abstract: A THz quantum cascade laser is used to investigate a target by directing a first beam of laser radiation from the laser at the target to thereby produce a second beam of laser radiation by interaction of the first beam with the target. Self-mixing of the first and second beams occurs within the laser and causes variations in a signal such as the operating voltage of the laser. An operating parameter of the laser that affects the interaction of the first beam with, the target is varied. The operating voltage is monitored and processed to determine phase and amplitude changes associated with material properties of the target. Consequently in one embodiment the invention provides for processing the variations in the signal to produce various images of the target.

  • Patent number: 10157561
    Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The first stage may be provided with straight black masking strips, whereas the second stage may be provided with angled zigzagging black masking strips. The angle of the zigzagging black masking strips and the ratio of the pixel pitch of the second stage to that of the first stage may be selected to maximize optical transmittance while minimizing Moire effects.
