An ion-beam etching apparatus includes: a plasma chamber configured to generate plasma from process gas in the plasma chamber; at least one plasma valve coupled to the plasma chamber; an ion-beam source in communication with the plasma chamber, wherein the ion-beam source is configured to extract ions from the plasma and generate ion-beams when a bias is applied to the ion-beam source; an etching chamber in communication with the ion-beam source, and configured to accommodate an object to be etched; at least one etching valve coupled to the etching chamber; and at least one exhausting pump connected to either one or both of the plasma chamber and the etching chamber by the plasma valve and the etching valve, respectively, wherein the at least one exhausting pump is configured to receive and exhaust radicals in either one or both of the plasma chamber and the etching chamber by the plasma valve and the etching valve, respectively.

Ion beam etching apparatus

Disclosed is an inductively-coupled plasma-generating device including: a first power supply for supplying high frequency power; a second power supply for supplying low frequency power; a single coil-based plasma source including at least two antennas which comprise a first antenna having one end as a grounded end and the other end, wherein the first power supply is connected to the first antenna at a point thereof adjacent to the grounded end to receive the high frequency power; and a second antenna surrounded by the first antenna, wherein the second antenna has one end connected to the first antenna and the other end as a low frequency power receiving end connected to the second power supply; and a gas supply for supplying a gas, wherein the gas is excited into plasma by the single coil-based plasma source.
