    摘要: A plasma processing method in which plasma can be ignited stably with a low radio frequency power and a low gas pressure even after long time operation by applying a DC voltage of −0.5 kV, for example, from a DC power supply (118) to a lower electrode (104) before a radio frequency power is applied from a radio frequency power supply (114) to the lower electrode (104) through a matching unit 112 when the surface of a wafer W mounted on the lower electrode (104) disposed in a processing container (102) is subjected to a specified plasma processing with plasma of a processing gas formed by applying a radio frequency power to the processing gas introduced into the airtight processing container (102).
