    Abstract: A substrate processing method includes inserting a substrate from an outside into a processing space, supplying a process gas from a gas supply unit to the processing space, producing plasma based on the process gas, performing an etching process for the substrate using ions included in the plasma, and discharging a processed gas produced in the etching process through a discharge part. The discharge part includes a first slit extending through a flange part, and a second slit connected to the first slit while extending through a side wall part connected to the flange part. A vertical length of the first slit is equal to a vertical length of the second slit. A horizontal length of the first slit is about 5 times to about 7 times the vertical length of the first slit.

    Abstract: A substrate processing apparatus includes a process chamber having an internal space; upper and lower electrode portions facing each other in the internal space; and a gas supply unit configured to supply cooling gas to a bottom surface of a substrate seated on the lower electrode portion. The gas supply unit may include a gas supply source outside the process chamber and configured to provide a cooling gas, and a gas filter connected to the gas supply source and including one or more wall surfaces at least partially defining a gas flow path for the cooling gas. The gas filter may include a first and second regions formed of respective materials having different dielectric constants. The first and second regions may be configured so that the cooling gas flowing along the gas flow path flows upwardly concurrently with colliding with a wall surface of the gas flow path.
