TIPS:  Do you have Unused ports on your Front Flange?

  Try Port Plugs

Unused ports on your Front or Rear Flange often get filled up with residue or byproducts from processes such as Silicon Nitride and Teos.  Help eliminate potential particle problems by installing Port Plugs.  Port Plugs will seal all unused holes without obstructing clearance in the process chamber.
