A Wafer Tumbler is a specialized device used in the semiconductor manufacturing process. It is designed to hold and rotate silicon wafers during various stages of production, such as cleaning, etching, or coating. This rotation ensures even treatment of the wafer's surface, which is crucial for producing high-quality microchips. The tumbler typically features a cylindrical shape and is made from materials that can withstand chemical exposure and high temperatures. By maintaining a controlled environment, the Wafer Tumbler helps prevent contamination and damage to the delicate wafers, ultimately contributing to the efficiency of the overall fabrication process.
