PROCESS AND APPARATUS FOR TREATING WORKPIECES IN A VACUUM CHAMBER INTO WHICH A GAS IS INTRODUCED |
摘要 |
A method and apparatus for obtaining a uniform gaseous molecular field under high vacuum conditions encountered in a dry etching process. In the method a source of a gas is provided and introduced into a manifold. The manifold feeds at least one nozzle and the gas is passed through the manifold and through the nozzle into a chamber maintained under vacuum conditions. The pressure of the gas and the configuration of the manifold and nozzle are such that the gas is caused to exit from the nozzle into the chamber under vacuum at sonic velocity. |
