摘要: A plasma processing apparatus using a capacitive coupled plasma (CCP) source requiring a low pressure range of about 25 mT or less and a method thereof are disclosed. Plasma source power may be applied in a pulse mode to either one of upper and lower electrodes in a chamber, which generates plasma and processes a semiconductor substrate, and plasma maintaining power may be continuously applied to the other of the upper and lower electrodes, such that a stable pulse plasma process may be performed in a low pressure range of about 25 mT or less.
