| Abstract: | A self-developed automatic liquid supply system was presented. It was suitable for multiple SVG7000 hot well LPTEOS vertical furnace. The structure, circuit principle and process flow of the automatic liquid supply system were introduced in detailed. Compared with traditional automatic liquid supply systems, the proposed system mainly added multi-loop control elements and optimized the time of automatic liquid supply. It had the characteristics of controlling multiple equipment at the same time and keeping the liquid level consistent before each operation procedure. By comparing the equipment operation data before and after using the system, the stability of the equipment was effectively improved by more than 10 percent after using the automatic liquid supply system. |
