Industry & Occupation
Classification
Summary
This occupation involves cleaning the surface of wafers with chemicals or water in the semiconductor manufacturing process to remove impurities and residues.
Description
Wafer cleaning workers are specialists who set wafers into various cleaning equipment (such as wet benches and spin rinse dryers) in cleanrooms and use chemicals or ultrapure water to remove surface contamination and fine particles. They are required to dilute chemical solutions, manage concentrations, adjust cleaning process conditions, and strictly adhere to safety procedures and cleanroom rules. They also inspect wafers after cleaning using microscopes or inspection equipment to check for defects or residues. Collecting and reporting data for process stabilization and improvement is also an important task.
Future Outlook
With the increasing demand for semiconductors, the importance of the cleaning process will be maintained. Amid advances in more sophisticated miniaturization対応 and the introduction of automation technologies, the demand for high-precision workers is expected to remain stable.
