    • An air inflow detection device of a vacuum chamber and a method thereof are provided to detect an air inflow in a vacuum chamber although plasma is not generated in a vacuum room. An inflow detection room(210) of an air inflow detection chamber(200) is connected to a vacuum chamber(10). A reference gas and an air generate plasma in the air inflow detection room by a plasma source(300). An optical emission analyzer(250) is installed in one side of the air inflow detection chamber. The optical emission analyzer detects a light intensity having wavelength related to the reference gas and a light intensity having wavelength related to the air among lights generating the plasma. A control part(400) determines an air inflow by using the detected light intensity.

    • PURPOSE: A high-density plasma apparatus for depositing a thin film is provided to enhance uniformity of plasma by preventing a charge-up phenomenon without reducing the gap-fill capacity. CONSTITUTION: A reaction chamber(40) includes a wafer stage(42) and an injector. A wafer is loaded into the wafer stage. The injector is installed at an upper part of the wafer stage in order to inject the source gas for forming plasma. An ICP unit and a CCP unit are installed around the reaction chamber in order to form the source gas plasma to an upper part of the wafer stage. The CCP unit includes an LF pulse generator(54) for applying LF pulses to a wafer stage and a VHF generator(52) for applying VHF or VHF pulses. The ICP unit is formed with a coil and an RF matching unit(50).

    • PURPOSE: An inductively coupled plasma generator having a serpentine coil antenna is provided to enhance the uniformity of plasma, reduce the inductance of an antenna, and restrict a capacitive coupling effect by improving a structure of the inductively coupled plasma generator. CONSTITUTION: An inductively coupled plasma generator having a serpentine coil antenna includes a reaction chamber(110), an antenna(120), and an RF power supply(132). The inside of the reaction chamber(110) is in a state of vacuum. The antenna(120) is installed at an upper part of the reaction chamber. The antenna is used for ionizing reaction gases injected into the inside of the reaction chamber and generating plasma. The RF power supply(132) is connected to the antenna in order to supply the RF power to the antenna. The antenna is formed with a plurality of coils having different radiuses. One of the coils is formed with a serpentine coil, which is wound in zigzags along the circumferential direction.
