Processing system
First Claim
1. A processing system comprising:
- a processing vessel defining an airtight processing chamber;
an upper electrode disposed in an upper region of the processing chamber;
a lower electrode disposed below and opposite to the upper electrode in the processing chamber, and a radio frequency power source connected at least to either the upper or the lower electrode;
wherein the upper electrode includes a side facing into the processing chamber towards the lower electrode, the upper electrode side having a plurality gas discharge holes to supply a predetermined process gas therethrough into the processing chamber, resin insulating members, each provided with a through hole permitting the process gas to pass through, are fitted from the upper electrode side facing the processing chamber into the gas discharge holes, respectively, each of the gas discharge holes is provided with a shoulder, each of the insulating members is provided with a step, and each of the insulating members are positioned in the gas discharge hole with its step in contact with the shoulder of the gas discharge hole.

Abstract
A processing system has an upper electrode with gas discharge holes of a shape corresponding to the external we of insulating members. The insulating members are formed of a poly(ether etherketone) resin, a polyimide resin, a poly(ether imide) resin or the like. Each insulating member has a step at its outer surface and an internal longitudinal through hole tapered to expand toward the processing chamber. The insulating members are pressed in the gas discharge holes to bring the steps into contact with shoulders formed in the sidewalls of the gas discharge holes. A part of each insulting member, as fitted in the gas discharge hole, projects from a surface of the upper electrode that faces a susceptor.
