Patent ID: 7777178

Claim:
A plasma generating apparatus using a neutral beam applied to etching atomic layers, comprising: a plasma generating part formed of a quartz cup and generating plasma; a radio frequency (RF) applying antenna disposed at the periphery of the plasma generating part; a cooling water supply part disposed at the periphery of the plasma generating part; and an igniter in direct communication with the plasma generating part; wherein the igniter has a higher local pressure than a local pressure of the plasma generating part at the same gas flow rate, wherein the plasma generating apparatus is configured to support a substrate below the plasma generating part allowing generated plasma to etch the substrate, wherein the igniter does not have a separate power supply, the igniter being configured to generate plasma in response to a RF signal generated from the RF applying antenna, the igniter being disposed on the plasma generating part, wherein a gas for generating plasma is supplied into the igniter in a direction substantially perpendicular to a surface of the substrate, the plasma generated by the igniter being supplied to the plasma generating part in the direction substantially perpendicular to the surface of the substrate from an upper region of the plasma generating part to a lower region of the plasma generating part, wherein the etching process is an etching of atomic layers.
