Abstract:
A plasma processing method comprising the steps of:setting a plurality of cylindrical substrates in a depressurizable, cylindrical reaction vessel; and decomposing a source gas supplied into the reaction vessel by a high frequency power to effect a plasma processing on the plurality of cylindrical substrates; wherein the plurality of cylindrical substrates are placed at equal intervals on the same circumference and are equidistant from the cylindrical reaction vessel, wherein the high frequency power is introduced from a plurality of high frequency power supplying means, the number of high frequency power supplying means being equal to or less than the number of cylindrical substrates, and wherein the high frequency power is introduced from the plurality of high frequency power supplying means provided at equal intervals on a concentric circle having a larger diameter and the same center as the placing circumference for the cylindrical substrates, thereby carrying out formation of deposited films.
