Abstract:
The plasma processing system for plasma-processing an object to be processed, arranged in a plasma producing space, the plasma processing system comprising:an upper electrode arranged in a sealed processing chamber;a lower electrode, arranged so as to face the upper electrode, for mounting thereon the object to be processed;high frequency power applying means for applying a predetermined high-frequency power between the upper and lower electrodes to form a plasma in said plasma producing space between the upper and lower electrodes;an inductively coupled antenna wound by a predetermined number of turns capable of applying a predetermined high-frequency power so as to surround the periphery of said plasma producing space, said antenna being shielded by a grounded member on sides other than the side of said plasma producing space;an insulating wall provided between said antenna and said plasma producing space; andan exchangeable insulating member between said upper electrode and said antenna, for covering a peripheral portion of said upper electrode on a side facing said plasma producing space, and for covering a portion of said antenna on a side facing said plasma producing space.
