摘要: That surface of an electrode plate 20 which is opposite to a susceptor 10 has a projection shape. The electrode plate 20 is fitted in an opening 26a of shield ring 26 at a projection 20a. At this time, the thickness of the projection 20a is approximately the same as the thickness of the shield ring 26. Accordingly, the electrode plate 20 and the shield ring 26 form substantially the same plane. The major surface of the projection 20a has a diameter 1.2 to 1.5 times the diameter of a wafer W. The electrode plate 20 is formed of, for example, SiC.

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).
