Abstract:
A plasma processing apparatus of exciting a processing gas into plasma by applying a high frequency power between an upper electrode and a lower electrode provided within a processing chamber and performing a plasma process on a target object to be processed with the plasma includes a DC power supply configured to apply a DC voltage to the upper electrode; a ground electrode connected to the DC power supply; and an annular shield member provided outside the ground electrode. A groove is formed into a downward recess at an outer peripheral portion of the ground electrode, and an upper end of the shield member is positioned above an upper end of the peripheral portion of the ground electrode. A protruding portion, which is protruded toward a center of the ground electrode, is formed at a portion of the shield member positioned above the ground electrode.

Claim (Index 3):
The plasma processing apparatus of  claim 1 ,\n wherein a ratio of a horizontal distance between a side surface of the groove at a central side of the ground electrode and a front end of the protruding portion with respect to a horizontal width of the groove is from about 1:1 to about 1:3.
