  • Publication number: 20110000428
    Abstract: A coating device includes a coating mechanism which includes nozzles for ejecting a liquid material onto front and rear surfaces of the substrate while rotating a substrate in an upright state at a predetermined coating position, a carrying mechanism which carries the substrate between a substrate loading position, the coating position, and a substrate unloading position, and a dummy substrate holding mechanism which holds a dummy substrate at a holding position which is a position different from the substrate loading position, the coating position, and the substrate unloading position, and at which the carrying mechanism is allowed to connect with the dummy substrate.

  • Publication number: 20100326354
    Abstract: A substrate processing system includes a processing unit, a substrate loading unit, a substrate unloading unit, and a carrying unit. A carrying device has a constitution in which a suction portion suctioning and holding a substrate is rotatable about an arm portion provided in a base portion and the substrate is rotated in the state where the substrate is held by a holding portion. A coating device has a constitution in which a liquid material is ejected from a nozzle to both surfaces of the substrate rotating in an upright state.

  • Patent number: 5706930
    Abstract: When a carrier arm is retracted, a semiconductor wafer carried thereon passes between three light-emitting elements and three light-detecting elements associated therewith. At this time, a controller determines six points on the outer circumferential edge of the semiconductor wafer based on signals from sensors made up of the light-emitting elements and the light-detecting elements. The controller selects three of the determined points, determines the center of a circumscribed circle passing through the selected three points, and regards the determined center as the center of the semiconductor wafer. Then, the controller controls movement of the semiconductor wafer toward a rotary-cup coating device, an evacuating drying device, or an edge cleaning device based on the center of the semiconductor wafer.

  • Patent number: 5332557
    Abstract: A plurality of workpieces are supported on a workpiece holder disposed over an opening defined in a horizontal base plate and connected to an evacuating device. A reaction chamber, which is supported on an arm of a lifting and lowering device, is vertically movable with respect to the base plate between a lowered position in which the reaction chamber defines a closed space which accommodates the workpieces therein and a lifted position in which the workpieces are exposed out of the reaction chamber. A heating device, which is supported on an arm of another lifting and lowering device, is vertically movable with respect to the base plate between a lowered position in which the heating device surrounds the reaction chamber and a lifted position in which the reaction chamber is exposed out of the heating device.
