Claims
- 1. A semiconductor manufacturing apparatus comprising:
- a vacuum processing chamber for implementing a processing to an object of processing under an atmosphere of reduced pressure; and
- a single spare vacuum chamber which is provided adjacent said vacuum processing chamber, said single spare vacuum chamber being provided therein with a conveyor arm to convey an object of processing,
- said conveyor arm having support portions for supporting at least two objects of processing, said conveyor arm being configured so that at least one object to be processed and one object that has been processed can be simultaneously conveyed by said conveyor arm, whereby an object of processing is conveyed to said vacuum processing chamber through said single spare vacuum chamber, and an object of processing is conveyed from said vacuum processing chamber through said single spare vacuum chamber.
- 2. A semiconductor manufacturing apparatus comprising:
- a vacuum processing chamber for implementing a processing to an object of processing under an atmosphere of reduced pressure; and
- a single spare vacuum chamber which is provided adjacent said vacuum processing chamber, said single spare vacuum chamber being provided therein with a support mechanism to support an object of processing and a conveyor arm to convey an object of processing,
- said support mechanism including two shelves which can move up and down and which can each support an object of processing.
- 3. A semiconductor manufacturing apparatus comprising:
- a vacuum processing chamber for implementing a processing to an object of processing under an atmosphere of reduced pressure; and
- a single spare vacuum chamber which is provided adjacent said vacuum processing chamber, said single spare vacuum chamber being provided therein with a support mechanism to support an object of processing and a conveyor arm to convey an object of processing,
- said support mechanism being suspended from a ceiling portion of said spare vacuum chamber and being configured so that a pair of rotatable fingers thereof hold an edge portion of an object for processing.
- 4. The semiconductor manufacturing apparatus of claim 1, wherein at least one of said support portions rotates about a shaft.
- 5. The semiconductor manufacturing apparatus of claim 1, wherein said object of processing is a semiconductor wafer.
- 6. The semiconductor manufacturing apparatus of claim 1, wherein said processing is etching processing.
- 7. The semiconductor manufacturing apparatus of claim 3, wherein said support mechanism is provided with either heating means or cooling means therein.
- 8. The semiconductor manufacturing apparatus of claim 3, wherein said object of processing is a semiconductor wafer.
- 9. The semiconductor manufacturing apparatus of claim 3, wherein said support mechanism is configured so that at least one object to be processed and at least one object that has been processed can be simultaneously supported.
- 10. The semiconductor manufacturing apparatus of claim 1, further including a support mechanism which includes two shelves which can each support an object of processing.
- 11. The semiconductor device manufacturing apparatus of claim 1, wherein said support portions are configured
- to be symmetrical about a shaft, to support an object to be processed thereon, and to rotate about said shaft.
