Summary: | The present invention provides a method of reducing the overhead time associated with a high density ion metal plasma process. The method provides flowing a gas at a first flow rate and exhausting the chamber at a constant rate so that the rate at which gases are exhausted from the chamber at a steady state equals the flow rate of gases into the chamber. Another method provides flowing a gas at a first rate and then at a second flow rate which is about equal to the rate at which the gas is exhausted from the chamber at a steady state. |
