  • Publication number: 20140023826
    Abstract: To provide a method for producing a coating film, containing: coating a base with a coating material containing a photocurable resin, a photopolymerization initiator, and a solvent; leaving the coated base to stand for longer than 0 minutes but 20 minutes or shorter at 50° C. or lower; and then applying ultraviolet rays to the coated base to thereby produce a coating film on the base.
    Type: Application

  • Patent number: 6861328
    Abstract: An a-Si film is patterned into a linear shape (ribbon shape) or island shape on a glass substrate. The upper surface of the a-Si film or the lower surface of the glass substrate is irradiated and scanned with an energy beam output continuously along the time axis from a CW laser in a direction indicated by an arrow, thereby crystallizing the a-Si film. This implements a TFT in which the transistor characteristics of the TFT are made uniform at high level, and the mobility is high particularly in a peripheral circuit region to enable high-speed driving in applications to a system-on glass and the like.

  • Patent number: 6821343
    Abstract: A semiconductor manufacturing apparatus emits an energy beam for crystallizing a semiconductor film formed on a substrate. The apparatus can output a plurality of energy beams continuously in relation to time and move the energy beams to scan a target to be irradiated. The output instability of the energy beam is smaller than ±1%/h. The noise (optical noise) indicating the instability of the energy beam can be not more than 0.1 rms %.
