    摘要: A plasma processing device includes a susceptor, processing vessel, dielectric plate, antenna, and projection. The susceptor has a stage surface on which a target object is to be arranged. The processing vessel accommodates the susceptor and has an opening in a side which opposes the stage surface of the susceptor. The dielectric plate closes the opening of the processing vessel. The antenna supplies a high-frequency electromagnetic field into the processing vessel through the dielectric plate. The projection projects from a surface of the antenna which opposes the dielectric plate toward the dielectric plate. The projection is conductive at least at its surface. A plasma processing method is also disclosed.

    摘要: A plasma processing apparatus has a vacuum vessel 2, an annular, transparent plate 23 put on the upper open end of the vacuum vessel 2 and a shower head 50 fitted in an opening formed in a central part of the annular transparent plate 23. A waveguide 25 has an outer guide member 25b and an inner guide member 25a connected to the shower head 50. Film forming gases including a CF gas is supplied through the inner guide member 25a and the shower head 50 into the vacuum vessel 2. A plasma producing gas, such as Ar gas, is supplied through an opening formed in the side wall at a position above the ECR point into the vacuum vessel 2. Active species of the film forming gases are distributed uniformly over the surface of a wafer. The interior of the shower head 50 formed of a metal is not contaminated with particles because the plasma does not flow into the shower head 50.

    摘要: A plasma processing apparatus has a vacuum vessel, a high-frequency power generator that generates a high-frequency wave, a waveguide for propagating the high-frequency wave generated by the high-frequency power generator into the vacuum vessel to produce a plasma by ionizing a processing gas supplied into the vacuum vessel and to process a semiconductor wafer supported on a support table in the vacuum vessel. A reflection coefficient measuring unit 5 is combined with a waveguide 35 to take data on a ratio &Ggr;0 of advancing wave from the high-frequency power generator 4 and reflected wave from the plasma and phase &thgr; of reflection coefficient. Factors dominating the electron density of the plasma including the output power of the microwave power generator are controlled on the basis of the measured data, whereby the electron density is controlled and stable processing is ensured.
