Reduction in mobile ion and metal contamination by varying season time and bias RF power during chamber cleaning |
摘要 |
The present invention provides a method and apparatus for reducing the concentration of mobile ion and metal contaminants in a processing chamber by increasing the bias RF power density to greater than 0.051 W/mm2 and increasing the season time to greater than 30 seconds, during a chamber seasoning step. The method of performing a season step in a chamber by depositing a deposition material under the combined conditions of a bias RF power density of about 0.095 W/mm2 and a season time of from about 50 to about 70 seconds, reduces the mobile ion and metal contaminant concentrations within the chamber by about one order of magnitude.
