    摘要: In a parallel plate type plasma processing apparatus (1), a baffle plate (28) is fitted between a ceiling (2b) and side wall (2a) of a chamber (2). The baffle plate (28) confines plasma into the upper portion of the chamber (2), and at the same time, constitutes a return route of a return current to a high frequency power source (27). A return current flowing through the baffle plate (28) returns to the high frequency power source (27) via the ceiling (2b) of the chamber (2).
