Description

[0002] The semiconductor baffle is an annular etching baffle used in the high-end process of chip semiconductor etching. Semiconductor baffle stripping refers to a process in the semiconductor production process. After the semiconductor has undergone the etching process, the required pattern has been obtained, but this layer of pattern is etched under the protection of a dry film or a wet film. Because the etching solution will corrode the conductive metal on the baffle, a dry film or a wet film is used to protect the required pattern. However, after obtaining the required pattern, the dry film or wet film covering the baffle must be removed. Most factories use NaOH solution as the solution used to remove the film on the baffle.

[0003] Since the semiconductor baffle is annular and the diameters of semiconductor baffles of different specifications are usually different, it is difficult to brush semiconductor baffles of different sizes in batches, and brushing the semiconductor baffles one by one is inefficient, and after the film stripping and cleaning are completed, they are usually left to drain. However, the draining time is often greatly affected by the environment. For a low temperature and windless environment, the drying time is long, resulting in low cleaning efficiency.
