Abstract:
1. An apparatus for treating the surface with neutral particle beams, comprising: a) an antenna container which comprises an antenna supporting panel by which antennas connected to a high frequency power supply through a RF feed-through are supported, an air inlet port, an air outlet port, an air inlet valve and an air outlet valve; b) a plasma generating part which comprises a gas inlet valve and a gas outlet valve regulating the inner pressure thereof, a gas inlet port and a gas outlet port, and which transfers a gas introduced through the gas inlet port into plasma ions with high frequency power supplied from the high frequency power supply; c) a neutral particle generating part located below the plasma generating part, which comprises at least one metal plate having multiple penetrating holes therein and comprised of or coated with a metal whose atoms are substantially heavier than the atoms of the gas introduced into the plasma generating part, and which transfers the plasma ions generated in the plasma generating part into neutral particle beams by the collision of the plasma ions with the metal plate; and, d) a treating part below the neutral particle generator, which comprises a target holder to load a target to be treated and an exhaust pipe, and into which the target is treated with the neutral particles generated in the neutral particle generating part, wherein, the antenna container and the plasma generating part are interconnected by outer vacuum induction units comprised of the air outlet port, the air outlet valve, the gas outlet port and the gas outlet valve such that the deterioration of the antennas by plasma is prevented.
