Installed in a processing vessel (22) is a mounting block (24) on which a semiconductor wafer (W) is mounted. Microwaves, which are generated by a microwave generator (76), are introduced into a processing vessel (22) through a planar antenna member (66). The planar antenna member (66) has a plurality of slits (84) arranged along a plurality of circumferences, the circumferences forming non-concentric circles. The plasma density distribution in the radial direction of the planar antenna member (66) becomes uniform.

In a microwave plasma-processing device, a shower plate or plasma penetration window opposed to a board to be processed is recessed on the side opposed to the board to be processed, whereby a decrease in plasma density in the peripheral region of the board to be processed is compensated. As a result, even when plasma processing at low pressure, such as etching, is effected, stabilized uniform plasma is maintained in the vicinity of the surface of the board to be processed. Further, such arrangement enhances ignition of plasma.

A wafer (101) to be plasma-treated is placed on a first electrode (102). Means (103) applies a magnetic field to the wafer surface to be plasma-treated. In the periphery of the first electrode (102) is arranged an auxiliary electrode (104), on the back (105) of which a plasma is produced. Electrons in the plasma are drifted from the front (106) to back (105) of the auxiliary electrode (104) and vice versa.

This instrument can measure parameters of a plasma accurately and easily even though the plasma is excited by a high-frequency. The instrument for measuring parameters of a plasma generated in a vacuum chamber by high-frequency discharge at a given frequency comprises a wire (106) for electrically connecting a first electrode (101) arranged in a space where a plasma is produced and a terminal (110) arranged outside the vacuum chamber for taking out signals, and a first insulator (105) so arranged as to cover at least a part of the surface of the wire therewith. The absolute value of the impedance at the given frequency between the first electrode and the ground when looking into the terminal side from the first electrode is five times or more the absolute value of the impedance at the given frequency between the first electrode and the plasma in a state where no direct current flows through the first electrode.
