Abstract: A plasma etching method includes disposing first electrode and second electrodes; preparing a part in a processing chamber; supporting a substrate by the second electrode to face the first electrode; vacuum-evacuating the processing chamber; supplying a first processing gas containing an etchant gas into a processing space between the first electrode and the second electrode; generating a plasma of the first processing gas in the processing space by applying a radio frequency power to the first electrode or the second electrode; and etching a film on the substrate by using the plasma. Further, a resist modification process includes vacuum-evacuating the processing chamber; supplying a second processing gas into the processing space; generating a plasma; and applying a negative DC voltage to the part, the part being disposed away from the substrate in the processing chamber and injecting electrons discharged from the part into the resist pattern on the substrate.

Abstract: An apparatus, which performs a plasma process on a target substrate by using plasma, includes first and second electrodes in a process chamber to oppose each other. An RF field, which turns a process gas into plasma by excitation, is formed between the first and second electrodes. An RF power supply, which supplies RF power, is connected to the first or second electrode through a matching circuit. The matching circuit automatically performs input impedance matching relative to the RF power. A variable impedance setting section is connected to a predetermined member, which is electrically coupled with the plasma, through an interconnection. The impedance setting section sets a backward-direction impedance against an RF component input to the predetermined member from the plasma. A controller supplies a control signal concerning a preset value of the backward-direction impedance to the impedance setting section.
