Abstract: The inventive concepts provide a substrate treating apparatus. The apparatus includes a process chamber, a substrate support unit, a gas supply unit, a microwave applying unit, an antenna plate, a slow-wave plate, a dielectric plate, and an exhaust baffle, and a liner. The liner includes a body having a ring shape facing an inner sidewall of the process chamber, and a flange extending from the body into a wall portion of the process chamber. The flange prevents an electric field of a microwave and a process gas from being provided into a gap between the process chamber and the body. Thus, it is possible to inhibit particles from being generated by damage of the inner sidewall of the process chamber by plasma, and drift distances of the particles can be reduced to inhibit the particles from reaching a substrate.
