  • Buffer apparatus and thin film deposition system
    Patent number: 8328938
    Abstract: A buffer apparatus and a thin film deposition system are provided. The buffer apparatus is connected between a liquid material supply apparatus and a deposition machine. The buffer apparatus includes a container and a baffle. The container is used for containing a liquid material supplied from the liquid material supply apparatus. The top of the container has an input hole and an output hole. The baffle is disposed in the container and located under the input hole.

  • Method of cleaning turbo pump and chamber/turbo pump clean process
    Patent number: 8277567
    Abstract: 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.
