Abstract:
A method of reducing particles within a high density plasma deposition chamber employing a deposition chamber coil, the high density plasma deposition chamber configured for depositing a production layer by sputtering a target, the method comprising:depositing a pasting layer on a non-production object within the high density plasma deposition chamber by sputtering the target; andafter depositing the pasting layer, depositing a transitional layer on the non-production object, wherein the transitional layer comprises a production layer that is formed by sputtering the target and that transitions the high density plasma deposition chamber from a pasting environment to an environment in which a bias applied to a wafer support within the high density plasma deposition chamber couples to a first production wafer during a first cycle and couples to a second production wafer during a second cycle in substantially equivalent amounts.
