Claims
- 1. A fluid supplying and processing device comprising:
- carrier means for carrying a workpiece;
- a housing surrounding said carrier means;
- a plurality of fluid supply sources;
- a plurality of fluid guide pipes each having a distal end open to a cavity within said housing at a place above said carrier means; and
- communication means for selectively communicating said fluid guide pipes with said fluid sources;
- at least one of said fluid guide pipes has the distal end portion thereof inserted in the distal end of another of said fluid guide pipes so that both distal ends of said one and another of said fluid guide pipes are open to said cavity separately from each other,
- one of said fluid supply sources supplying a cleaning fluid,
- said communication means including a first means for selectively communicating said one of said fluid supply sources with said one and another of fluid guide pipes.
- 2. A fluid supplying and processing device according to claim 1, wherein said distal end portion of said one fluid guide pipe in said other fluid guide pipe surrounds a smaller-diameter one of said fluid guide pipes.
- 3. A fluid supplying and processing device according to claim 1, wherein at least two of said fluid guide pipes have at least distal end portions inserted side by side in said other fluid guide pipe.
- 4. A fluid supplying and processing device according to claim 1, in which said communication means further includes a second means for selectively communicating another than said one of the fluid supply sources with said one of the fluid guide pipes, and a third means for communicating said one of the fluid supply sources with said one of the fluid guide pipes as long as said second means interrupt its communication.
- 5. A fluid supplying and processing device according to claim 1, in which said workpiece is a disc carrying thereon a photo-resist layer already processed with a light beam, and said another of the fluid supply sources supplies a developing organic solvent for dissolving a non-cured portion of said photocurable layer.
- 6. A fluid supplying and processing device according to claim 5, in which said cleaning fluid is a deionized cleaning water.
- 7. A fluid supplying and processing device comprising:
- carrier means for carrying a workpiece;
- a housing surrounding said carrier means;
- a plurality of fluid supply sources;
- a plurality of fluid guide pipes each having distal ends open to a cavity within said housing at a place above said carrier means; and
- communication means for selectively communicating said fluid guide pipes with said fluid sources;
- at least one of said fluid guide pipes has a distal end portion inserted in a distal end of another of said fluid guide pipes so that both distal ends of said one and another of said fluid guide pipes are open to said cavity separately from each other,
- one of said fluid supply sources supplying a cleaning fluid,
- said communication means including a first open-close valve means for selectively communicating said another of said fluid supply sources with said one of the fluid guide pipes, a second open-close valve means for selectively communicating a different one than said one of said fluid supply sources with said one of the fluid guide pipes, and a third open-close valve means for communicating said one of the fluid supply sources with said one of the fluid guide pipes when said second open-close valve means is closed.
