Protective collar for vacuum seal in a plasma etch reactor |
摘要 |
A vacuum seal assembly that can be used in a plasma etch reactor to seal the chamber interior from the outside environment consists of a protective collar that is injection molded or machined of a high strength, high temperature and corrosion resistant thermoplastic material, the collar has an elastomeric gasket installed therein and is used in combination with a second elastomeric gasket to achieve a fluid-tight seal between two rigid surfaces made of silicon and quartz, respectively.
