Abstract:
In a plasma processing method includes a first stage of generating plasma of a first processing gas and a second stage of generating plasma of a second processing gas, are performed, a time difference between a start time point of a time period during which the second stage is performed and a start time point of an output of the second processing gas from a gas supply system is decided automatically according to a recipe. A delay time corresponding to flow rates of the first processing gas and the second processing gas in the second stage is specified from a function or a table.

Claim (Index 1):
A plasma processing method performed by a plasma processing apparatus,\n wherein the plasma processing apparatus comprises: a processing vessel; a gas supply system configured to supply a gas into the processing vessel; an electrode disposed within the processing vessel; a high frequency power supply configured to output a high frequency power; and a controller configured to control the gas supply system and the high frequency power supply, wherein, the plasma processing method comprises a first stage of generating plasma of a first processing gas within the processing vessel and a second stage of generating plasma of a second processing gas within the processing vessel after the first stage, the first processing gas is supplied into the processing vessel and the first high frequency power is supplied to the electrode over a first period during which the first stage is performed and a second period during which the second stage is performed after the first period, a power level of the high frequency power in the first period is set to be lower than a power level of the high frequency power in the second period, and wherein the plasma processing method further comprises: starting an output of the second processing gas from the gas supply system at an output start time point which precedes a start time point of the second period by a first time difference under the control of the controller, wherein the controller specifies, by using a function or a table which relates a flow rate of the first processing gas and a flow rate of the second processing gas to a delay time from a time point when the gas supply system starts the output of the second processing gas to a time point when the second processing gas is supplied into the processing vessel, a first delay time related to the flow rate of the first processing gas and the flow rate of the second processing gas in the second stage designated in a recipe, and sets the first delay time as the first time difference initially.
