Title:
MATERIAL CONTROL METHOD AND SYSTEM, AND STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/087726
Kind Code:
A1
Abstract:
The present application relates to the field of silicon wafer production, and in particular to a material control method and system, and a storage medium and an electronic device, wherein the material control method is applied to a material control system. The method comprises: acquiring a raw material list by means of a manufacturing execution module, and sending the raw material list to a processing module; acquiring, by means of the processing module, a re-pulled material that is generated during a production process and a plurality of types of raw materials that are indicated by the raw material list, and processing the re-pulled material and the plurality of types of raw materials, so as to obtain a material to be used; collecting, by means of the manufacturing execution module, material information of the material to be used, and sending the material information to a material management module; conveying, by means of the material management module and according to the material information, the material to be used to a warehouse; sending a material calling request to a material barrel management module by means of the manufacturing execution module; and acquiring, by means of the material barrel management module and from the warehouse, a target material to be used that has a target weight, loading said target material into a material barrel, and conveying the material barrel to a feeding position corresponding to a target single crystal furnace, so as to add said target material that has the target weight into the target single crystal furnace.
