Abstract
Examples of a substrate processing method include subjecting a substrate placed on a susceptor to plasma processing, applying power to an RF electrode facing the susceptor for only a predetermined static electricity removal time to generate plasma, thereby reducing an amount of charge of the substrate, measuring a self-bias voltage of the RF electrode while susceptor pins are made to protrude from a top surface of the susceptor and lift up the substrate, and by a controller, shortening the static electricity removal time when the self-bias voltage has a positive value, and lengthening the static electricity removal time when the self-bias voltage has a negative value.
