HIGH RATIO PLANETARY DRIVE SYSTEM FOR VACUUM CHAMBER

摘要

A high ratio planetary drive system, a vacuum processing chamber system incorporating the planetary drive system, and a method of operating the system are disclosed. The planetary drive system provides relatively slow planetary workpiece rotation for effecting processing (deposition and reaction) of thin films, in particular, optical thin films, with complete film oxidation, controlled film uniformity, reduced bearing wear and reduced heat dissipation.
