Plasma processing method

A plasma processing method is provided that includes a step of loading a substrate into a chamber where a plasma process is to be executed, a step of applying a high frequency bias power that has a lower frequency than a high frequency excitation power for plasma excitation to a mounting table on wh...

Beschreibung
Zusammenfassung:	A plasma processing method is provided that includes a step of loading a substrate into a chamber where a plasma process is to be executed, a step of applying a high frequency bias power that has a lower frequency than a high frequency excitation power for plasma excitation to a mounting table on which the substrate is mounted, and a step of applying a DC voltage to an electrostatic chuck configured to electrostatically attract the substrate that is mounted on the mounting table. The step of applying the DC voltage is performed after the step of applying the high frequency bias power.
