摘要: The invention provides a plasma processing method and plasma processing device for manufacturing semiconductor devices in which the number of foreign particles being adhered to the wafer is reduced greatly and the yield is improved. In a plasma processing device having a plasma source capable of controlling plasma distribution, the shape of a sheath/bulk boundary above the wafer is controlled to a convexed shape when the plasma is turned on and off. By adding a step of applying a low source power and wafer bias power when the plasma is turned on and off in order to realize an out-high plasma distribution, it is possible to form a sheath that is thicker near the center of the wafer and thinner at the outer circumference portion thereof.
