  • Publication number: 20060113021
    Abstract: Prior to the start of transfer of an insulation film to a substrate, the degree of opening of a butterfly valve is set small so that evaporation of a solvent component contained in the insulation film is suppressed and the fluidity of the insulation film is ensured at the start of the transfer. On the other hand, the butterfly valve is totally opened at the start of the transfer, so that the pressure inside a thin film forming chamber rapidly decreases and transfer of the insulation film to the substrate is performed always in a low-pressure state (high-degree of vacuum).

  • Publication number: 20050230035
    Abstract: Apparatus for forming a thin film pattern on the surface of a substrate. This apparatus is provided with: a transfer member having a thin film carrying surface which carries a thin film pattern; and a thin film transfer mechanism for joining the transfer member to a substrate for transferring, to the substrate, the thin film pattern on the thin film carrying surface. The thin film pattern may be a wiring film pattern. A gelatinous film may previously be formed on the substrate, and the thin film pattern may be transferred as embedded in the gelatinous film.

  • Patent number: 6918421
    Abstract: With a thin film bearing surface of a substrate directed toward an insulation film which is formed on a surface of a quartz plate, the substrate and the quartz plate are moved closer to each other and the insulation film is tightly adhered to the thin film bearing surface (adhering process). The quartz plate alone is then selectively peeled off, thereby completing transfer of the insulation film onto the substrate (peeling process). In this manner, the insulation film is disposed on the thin film bearing surface of the substrate, and a transportation mechanism then houses the substrate in a substrate cassette. Meanwhile, after the quartz plate is transported by the transportation mechanism to a cleaning unit and cleaned by the cleaning unit (cleaning process), the quartz plate is returned to a plate-like member cassette and waits in this cassette until reused next time.

  • Patent number: 6911088
    Abstract: A slit nozzle includes a solution feeding mechanism having an elastic element and a plurality of piezoelectric devices and embedded in a side surface of a flow passage near a slit in the slit nozzle. Control is effected so that the piezoelectric devices are vibrated to cause the elastic element to produce traveling waves toward the slit. A resist solution serving as a processing solution is pumped by the traveling waves, thereby to be discharged through the slit toward a substrate. This provides a substrate processing apparatus capable of smoothly discharging the processing solution to accomplish high discharge accuracy.

  • Patent number: 6859616
    Abstract: A semiconductor wafer is held by support pins horizontally. A susceptor and a heating plate are moved upwardly so that the semiconductor wafer is transferred from the support pins to the susceptor. At this time, a gas layer is sandwiched between the upper surface of the susceptor and the lower surface of the semiconductor wafer to cause the semiconductor wafer to float over the upper surface of the susceptor for about seventy seconds immediately after the semiconductor wafer is mounted on the upper surface of the susceptor. Then, flash lamps are lit up to perform flash heating while the semiconductor wafer is floating over the upper surface of the susceptor. Even when flashlight irradiation causes rapid thermal expansion of the wafer surface, the semiconductor wafer does not suffer a great stress. This can prevent the semiconductor wafer from breaking.

  • Patent number: 5916366
    Abstract: A substrate treating apparatus for performing a predetermined treatment of a substrate in a spin, has a spin motor including a rotor having a hollow opening centrally thereof, and a stator disposed coaxially with the rotor and having a hollow opening centrally thereof. The rotor includes holders for supporting the substrate in three peripheral positions thereof. A support mechanism switches the holders between a position for supporting the substrate, and a position retracted therefrom. The opposite surfaces of the substrate supported by the holders are cleaned with a cleaning solution supplied through nozzles. The holders have a substrate supporting force derived from a weight and magnetism of the support mechanism, to support the substrate reliably. A guide is disposed in the hollow of the rotor, and connected to the rotor. The holders are arranged in a substrate treating space formed inwardly of the guide. The holders are arranged on the guide.
