Method of cleaning turbo pump and chamber/turbo pump clean process

A method of cleaning a turbo pump is described. The turbo pump is coupled with a CVD chamber of depositing a material and thus accumulates the material therein. The method includes switching off the turbo pump and using another pump to pump a reactive gas, which can react with the material to form g...

Zusammenfassung:A method of cleaning a turbo pump is described. The turbo pump is coupled with a CVD chamber of depositing a material and thus accumulates the material therein. The method includes switching off the turbo pump and using another pump to pump a reactive gas, which can react with the material to form gaseous products, through the turbo pump. Thereby, the turbo pump is cleaned up and is prevented from being a particle source in subsequent CVD operations.
