Abstract
A plasma processing method includes: setting a temperature of a substrate support surface to a first temperature; supplying electric power from an electric power adjuster to a heater; before plasma is generated, when the temperature of the substrate support surface measured by a temperature sensor stabilizes at the first temperature, measuring first electric power supplied to the heater; after the plasma is generated, when the temperature of the substrate support surface measured by the temperature sensor stabilizes at the first temperature, measuring second electric power supplied to the heater; calculating an input heat quantity input from the plasma based on the first electric power and the second electric power; and correcting the first temperature to a second temperature based on the input heat quantity and a thermal resistance between the substrate support and the temperature sensor or between a substrate and the temperature sensor.
