Plasma processing apparatus

A plasma processing apparatus comprises means of supplying the microwave, a reaction chamber having a microwave lead-in opening, a microwave window for introducing the microwave provided by the microwave supply means into the reaction chamber through the microwave lead-in opening, and a supporting member having beams for supporting the microwave window. The apparatus has its microwave window divided in correspondence to areas of the supporting member divided by the beams. The apparatus can have a larger microwave window which is reinforced by the beams against the pressure at plasma generation, and is capable of processing large semiconductor substrates and glass substrates for liquid crystal display panels stably and uniformly.

A microwave plasma processing system, wherein a conductor disposed for controlling the anisotropy and the acceleration energy of ions in a plasma has inside a flow path for reactant gasses and a plurality of holes through which the gasses are to be blown toward a sample holder. A microwave plasma processing system, wherein the ratio of the total area of microwave transmission holes to the area of a conductor is set to be in a range of 0.25 to 0.65. A microwave plasma processing system, wherein each microwave transmission hole formed in a conductor has a dimension in the microwave traveling direction greater than that in a direction perpendicular to the traveling direction.

Microwave plasma processing system

A microwave plasma processing system has heating means for heating the wall of a reaction chamber, and an adhesion preventing member in which a cylinder disposed so as to be in contact with the inner face of a wall of the reaction chamber and a microwave reflecting plate having a gas discharge hole are integrally formed. A microwave plasma processing system has heating means for heating the wall of a reaction chamber, and a microwave reflecting plate which is attached to the inner face of a wall of the reaction chamber and which has a gas discharge hole.
