Abstract

A dry cleaning device adapted to clean a container component of a container of a semiconductor manufacturing process and adapted to clean the container component by carbon dioxide snowflakes. The dry cleaning device can first inspect the container component before and after cleaning, clean the container component by carbon dioxide snowflakes according to a predetermined cleaning working set, and forwards the container component to a next workstation once the cleaning of the container component is complete. The dry cleaning device is adapted to clean a container of a semiconductor manufacturing process in a fast and effective manner without involving any liquid solvents.
