Gas channels in the manifold are arranged on a plurality of levels to equalize the lengths of gas paths connecting the gas inlet to each of the plurality of nozzles. This configuration makes the flow rate of reactive gas supplied through each of the plurality of nozzles to the reaction chamber uniform.

    摘要: Provided is an ionized physical vapor deposition (IPVD) apparatus having a helical self-resonant coil. The IPVD apparatus comprises a process chamber having a substrate holder that supports a substrate to be processed, a deposition material source that supplies a material to be deposited on the substrate into the process chamber, facing the substrate holder, a gas injection unit to inject a process gas into the process chamber, a bias power source that applies a bias potential to the substrate holder, a helical self-resonant coil that produces plasma for ionization of the deposition material in the process chamber, one end of the helical self-resonant coil being grounded and the other end being electrically open, and an RF generator to supply an RF power to the helical self-resonant coil. The use of a helical self-resonant coil enables the IPVD apparatus to ignite and operate at very low chamber pressure such as approximately 0.1 mtorr, and to produce high density plasma with high efficiency compared to a conventional IPVD apparatus. Accordingly, a high efficiency of ionization of deposition material is achieved.

    摘要: A high-density plasma processing apparatus includes a processing chamber, having a susceptor for supporting an object to be processed positioned therein and a dielectric window positioned on the processing chamber to form an upper surface of the processing chamber. A reaction gas injection device injects a reaction gas into an interior of the processing chamber.

A waveguide guides a microwave generated by a microwave generator. A circular radiative tube, which is installed on the dielectric window around the ICP antenna and is connected to the waveguide, radiates a microwave toward the interior of the processing chamber via a plurality of slots formed through a bottom wall of the radiative tube.
