Abstract:
1. A plasma processing system comprising: a chamber for housing therein a substrate to be processed; first and second electrodes provided in said chamber so as to face each other, said first electrode having a first surface, and a second surface that is opposite to said first surface and that faces said second electrode; a high frequency electric power supply for supplying a high frequency electric power to said first electrode via a matching unit; a feeding member for feeding said high frequency electric power from said high frequency electric power supply through a feeding position to said first surface of said first electrode, the feeding position being a single position with respect to the first surface; a moving mechanism for moving the feeding position of said feeding member; evacuation means for maintaining the interior of said chamber in a predetermined reduced pressure state; and process gas feed means for feeding a process gas into said chamber, wherein said process gas is activated as plasma by said high frequency electric power to carry out a plasma processing; and wherein said moving mechanism substantially moves the feeding position of said feeding member on a circumference of a predetermined radius, which is concentric with said first electrode, on the first surface of said first electrode.
