摘要:
The invention disclosed defined a vertically extending passage through the rotary center of an inner cup or the rotary center of a spinner in a notary chemical treater, disposes a stationary cleaning fluid nozzle in the passage, and injects the cleaning fluid from the nozzle to clean a lid of the rotary chemical treater and the underside of an object treatment within the treater. The underside of the lid and the underside of the objective part are efficiently cleaned, and the need for sealing the movable parts against the cleaning fluid is eliminated because the nozzle is stationary, ensuring the prevention of the cleaning fluid from leaking.

A coating nozzle includes an elongate nozzle body having a coating solution reservoir defined longitudinally therein for being supplied with a coating solution from an external coating solution supply. The elongate nozzle body also has a coating solution holder defined therein and opening away from the coating solution reservoir, for holding a coating solution against falling off as droplets under surface tension of the coating solution. A plurality of passages are defined in the elongate nozzle body and held in communication with the coating solution reservoir and the coating solution holder, for supplying the coating solution from the coating solution reservoir to the coating solution holder.

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.

A rotating cup type liquid coating device with structure for suppressing pulsatory movement of the coated liquid when stopping rotation of the inner cup 3, includes a buffer space S formed for connecting an inner space of the inner cup 3 and an inner space of an outer cup 2 surrounding the inner cup, on an outer periphery of the inner cup 3 , through respective throttle portions 16, 17.
摘要:
A suction chuck and an inner cup are rotated in unison with each other to spread a coating solution uniformly over a planar object in the inner cup under centrifugal forces. Vent holes defined in an outer cup lid which closes an outer cup are held out of communication with vent holes defined in a ring-shaped closure member, so that the interior space in the outer cup is kept out of communication with the exterior space around the outer cup. The concentration of a solvent in the outer cup remains so high that no mist is produced in the outer cup. After the planar object has been coated and before the outer cup lid is opened, the ring-shaped closure member is turned to align the vent holes in the outer cup lid with the vent holes in the ring-shaped closure member, breaking any vacuum in the outer cup with ambient air introduced through the vent holes into the outer cup. Thereafter, the outer and inner cup lids are opened, and the coated planar object is taken out.
摘要:
A processing unit structure 1 a plurality of processing units 2, . . . , assembled together continuously in a horizontal direction, wherein a transfer portion 3 is provided on the top of each processing unit 2, . . . , for transferring the plate-like material to be processed between adjacent one of the processing units. A transfer device, such as a shuttle (SH) is provided in each of the transfer portions 3. Each processing unit 2 performs a series of processes on the plate-like material and is constructed with processing blocks 4 and 4 and a transfer portion 3 in the form of a transfer robot (R) positioned between the processing blocks 4 and 4. Further, each processing unit 2. . . is independent from one another so that it is possible to selectively add and remove different ones of the processing units with respect to the processing unit structure 1.
摘要:
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.
