Abstract
Abstract A manufacturing system in which the automatic control of the system and the automatic control of a process management are organically coupled, thereby to sharply reduce the number of workers to be engaged in the manufacture. In order to establish both the versatility necessary for multiple type of treatment and the high efficiency necessary for large-quantity treatments, the arrangement of respective treatment sections is made the job-shop-type, and the construction of treating devices themselves included in the treatment sections is made the flow-shop-type, to achieve the consecutive automation. In order to also automate the management of the process, a stocker in which unfinished products are put is situated in a specified place of the system such as the central part thereof, while the process is put forward in such a manner that a conveyor machine controlled by a control unit having a computer reciprocates between the stocker and the groups of treatment sections. The manufacturing system is suitable for the fabrication of semiconductor devices which have many kinds of articles where each kind of article needs to be mass-produced.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
256 words
A manufacturing system for providing a plurality of different treatments to semiconductor workpieces to manufacture semiconductor devices comprising: a conveyance path elongated along a predetermined path; a plurality of treatment sections, for subjecting the workpieces to respectively different treatments, said treatment sections being elongated relative to said conveyance path in a direction to intersect said conveyance path and arranged in side-by-side spaced relationship, each of said treatment sections having loading and unloading positions at a side facing said conveyance path; and conveyance means for moving the workpieces towards the loading positions and unloading positions of said respective treatment sections and along with conveyance path, the improvement wherein said plurality of treatment sections and said conveyance path are all located within a clean room area formed such that a first elongated portion of said clean room area is provided for said conveyance path and portions of said clean room area are provided for each of said treatment sections with the treatment section clean room portions being arranged in side-by-side spaced relationship along said first elongated portion and respectively joined to the first elongated portion of said clean room area; wherein said conveyance means includes a carrier capable of moving within the first elongated portion of said clean room area; and wherein said manufacturing system further comprises a preservation area located outside of said clean room area and adjacent to each of the treatment section clean room areas to permit access to each of said treatment sections from outside of said clean room area for repair and maintenance.
Claim 2
Dependent Claim
