Patent ID: 8604697

Claim:
An apparatus for generating plasma, the apparatus comprising: a vacuum chamber comprising a through-hole at a center of its top; and a plasma source part, comprising: a dielectric part configured to protrude upward along a circumference of the through-hole; an upper electrode coupled to seal an opened top of the dielectric part, the upper electrode configured to receive a supply of a Radio Frequency (RF) power; and an inductive coil configured to: spirally extend along an outer circumference surface of the dielectric part; and receive a supply of the RF power, the plasma source part being configured to generate plasma within the vacuum chamber, wherein the through-hole is provided in a partial region of an adaptor disposed below the dielectric part, a part of the vacuum chamber body comprising the adaptor, wherein: the adaptor further comprises at least one additional through-hole; and the apparatus further comprises: at least one additional plasma source part installed on the at least one additional through-hole, the at least one additional plasma source part comprising a same construction as the plasma source part; and a conductive interference prevention part configured to prevent interference between the plasma source parts.
