Claim Text:
1. A plasma processing method using a processing apparatus having a processing chamber for processing a substrate by a plasma of a processing gas, the method comprising: mounting the substrate onto a mounting table provided in a lower portion of the processing chamber; supplying the processing gas between a first electrode and a second electrode provided in an upper portion of the processing chamber, wherein the first electrode has a first plurality of linear members horizontally extending in parallel with each other and the second electrode has a second plurality of linear members horizontally extending in parallel with each other, the first plurality of linear members being arranged in a one-to-one corresponding manner with the second plurality of linear members and each of the first plurality of linear members being vertically opposite the corresponding one of the second plurality of linear members; applying an RF power between the first electrode and the second electrode so that the processing gas supplied between the first electrode and second electrode is converted to the plasma of the processing gas; and exhausting the inside of the processing chamber from a lower portion of the processing chamber to a vacuum level.
