Abstract:
A plasma source and a plasma generating apparatus using the same are provided to concentrate a field of a radial shape to a substrate to be treated by mounting a ferrite structure on a linear type antenna. One linear antenna(21) forms a loop type by connecting one side of a first antenna of a linear type to one side of a second antenna of a linear type. A ferrite structure(23a) is positioned in each top part of the first antenna and the second antenna of the linear antenna. The ferrite structure concentrates a field formed into a radial type from the antenna to a specific direction. The ferrite structure is formed into an arch type.

Abstract:
Disclosed is a plasma generator. The plasma generator includes a main body for generating plasma through a pulse signal applied to a multi-electrode; a source power for applying pulse signals having mutually different frequencies to the multi-electrode; and a main control unit for adjusting a clock signal applied to the source power to synchronize the pulse signals applied to the multi-electrode so that the main control unit controls properties of the plasma by controlling the pulse signals to the source power.
Abstract:
PURPOSE: A hybrid plasma source and a plasma generating apparatus using the same are provided to perform low pressure processing by forming an inductively coupled inner plasma source surrounding a capacitively coupled internal plasma source. CONSTITUTION: RF power is respectively connected to a first electrode(120), a second electrode(140), and one or more unit coils(220). An electric field is induced by applying the RF power to a first electrode and a second electrode. Reaction gas is inserted through a gas inlet installed at a lateral exterior wall(160) of a plasma generating device. The reaction gas is changed into a plasma state by the electric field induced inside a second space. Unit coils receiving power from the RF power generates the electric field. The electric field is left out in the second space. The induced electric field turns gas into plasma by generating discharge in the reaction gas inserted through the gas inlet.
