Technical Field

[0001] The utility model relates to the technical field of polysilicon cleaning, in particular to a cleaning frame for cleaning a polysilicon ring. Background Art

[0002] During the whole process of polysilicon ring processing, dewaxing is required. Since dewaxing cannot completely remove the sticky wax on the surface of the workpiece, a high-temperature degreasing and cleaning step is added. A tooling is needed to fix the product when cleaning the product. At the same time, it prevents the workpiece from being damaged when it collides with the cleaning tank during the cleaning process, and plays a role in fixing and protecting the product. Polysilicon is an important material in semiconductor manufacturing, and its surface cleanliness has an important influence on the performance of the product. Traditional cleaning methods often make it difficult to completely remove impurities on the surface of polysilicon, resulting in a decrease in product performance. This makes the development of an efficient and reliable cleaning frame an urgent need in the current semiconductor manufacturing field. To this end, we propose a cleaning frame for cleaning polysilicon rings. Utility Model Content
