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.
