摘要
In a plasma treating apparatus, a ceramic porous substance having a three-dimensional network structure in which a frame portion formed of ceramic containing alumina is provided continuously like a three-dimensional network is used for the material of an electrode member for the plasma treating apparatus to be attached to the front surface of a gas supplying port of an electrode for plasma generation, and a gas for plasma generation is caused to pass through a hole portion formed irregularly in the three-dimensional network structure. Consequently, the distribution of the gas to be supplied is made uniform to prevent an abnormal discharge so that uniform etching having no variation can be carried out.
