Technical Field
[0001] This utility model relates to the field of semiconductor spray trays, specifically a semiconductor spray tray that is easy to clean. Background Technology
[0002] Semiconductor spray trays are a key piece of equipment in the semiconductor manufacturing process, primarily used for liquid spraying. Their principle is to uniformly disperse liquids (such as chemical reagents, cleaning solutions, etc.) into small droplets through an internal channel system and spray them onto the surface of the semiconductor wafer. It's like a precision spray head, but with a more complex structure and function, aiming to achieve efficient and uniform liquid treatment of semiconductor materials. Currently, semiconductor spray trays are often fixedly connected to spray pipes, which is inconvenient when cleaning is required. Therefore, a semiconductor spray tray that is easy to clean is needed.
[0003] Existing semiconductor spray trays are inconvenient to disassemble and clean during use. If residual chemical reagents, impurities, and other substances are not cleaned thoroughly and promptly after use, they will pose a serious risk of contamination to subsequent production processes. Furthermore, the current spray trays have poor corrosion resistance. Therefore, there is an urgent need for a semiconductor spray tray that is easy to clean. Utility Model Content
