The 2-inch Wafer Cassette Holder is a precision carrier device specifically designed for the semiconductor, optoelectronics, and micro/nano manufacturing industries. It is primarily used for securely holding, storing, and transporting 2-inch (50.8mm) wafers or thin-film materials. Manufactured from high-purity materials, it ensures contamination-free and mechanical-damage-free operation during fabrication, inspection, or experimental processes. Its standardized design ensures compatibility with various semiconductor equipment (e.g., lithography machines, etching systems, and deposition devices) and makes it widely applicable in both research laboratories and industrial production lines.

2 inch Wafer Cassette Primary Applications
