Patent ID: 7842159

Claim:
A plasma processing apparatus for a very large area, the apparatus comprising: a stage loading a substrate to be subjected to an etching or deposition process; a reaction chamber detachably coupled with the stage and having a plasma source region; a cover covering the reaction chamber; an assembly frame coupling the reaction chamber with the cover; first and second antenna sources disposed in the plasma source region, and each source having a plurality of antenna assemblies disposed in parallel, the plurality of antenna assemblies having a power supply connected to one side thereof and a ground connected to the other side thereof; a plurality of magnet assemblies disposed on both sides of each antenna assembly; and a first power supply, connected to the first antenna source, for applying a first power having a first frequency to the first antenna source, and a second power supply, connected to the second antenna source, for applying a second power having a second frequency to the second antenna source, the first frequency and the second frequency being different in magnitude with each other, wherein the first and second antenna sources comprise m and m-1 antenna assemblies, respectively, and the antenna assemblies of the first antenna source and the antenna assemblies of the second antenna source are alternately disposed.
