Abstract:
1. A high-density plasma processing apparatus, comprising: a processing chamber, including a susceptor for supporting an object to be processed positioned therein, and a dielectric window positioned on the processing chamber to form a top wall of the processing chamber; a reaction gas injection device for injecting a reaction gas into an interior of the processing chamber; an inductively coupled plasma (ICP) antenna, which is installed on a center of the dielectric window and disposed external to the processing chamber, for transferring radio frequency (RF) power from an RF power supply to the interior of the processing chamber; a waveguide for guiding a microwave, for generating plasma, generated by a microwave generator; and a circular radiative tube, which is installed on the dielectric window around the ICP antenna and is connected to the waveguide, for radiating a microwave toward the interior of the processing chamber via a plurality of slots formed through a bottom wall of the circular radiative tube.
