发明名称 RF matching network of a vacuum processing chamber and corresponding configuration methods
摘要 A RF matching network is described, and which includes a 1st to nth RF generators, and wherein each RF generator has a different frequency, and wherein the frequencies of the 1st to the nth RF input ports decline in sequence, and wherein between the ith frequency RF input port, and the output port is a ith circuit, which has a high impedance at the output port to all RF generator frequencies other than the ith frequency; and wherein the ith circuit, when connected to a RF generator with the ith frequency, and wherein measuring from the output port to the ith circuit, the ith circuit has a first impedance at the ith frequency; and when measuring from the output port in the opposite direction to the ith circuit, the ith circuit has a second impedance at the ith frequency; and wherein the first impedance is a substantial conjugate match of the second impedance.
