Abstract: The present invention relates to a fag hoisting pole with key characteristics in that a “rainwater adhesion suppressing rod” is installed at a top end of a flag hanging steel bar provided with an upper “fixed structure” P and a lower “rotating structure” Q to execute a “rotation method”, so as to inhibit a surface adhesion phenomenon of a large flag wet in the rain while minimizing an adhesion area thereof, and at the same time, an adhesion part becomes a starting point for inducing ventilation into the adhesion part, whereby a speed of unfolding the large flag from the surface adhesion part thereof to the original state can be maximized.

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.

Abstract: Provided is a substrate treating apparatus. The substrate treating apparatus includes a processing chamber, a substrate supporting unit, an antenna plate, a dielectric plate, a gas supplying unit or the like. In the gas supplying unit, an excitation gas injection unit is provided at a position higher than that of a process injection unit so as to inject an excitation gas containing an inert gas from a position higher than that of a process gas, thereby preventing a damage of the dielectric plate, generating high-density plasma, and preventing degradation of process performance in a process which is performed under a process pressure of 50 mTorr or more or uses a hydrogen gas.

Abstract: Provided is a substrate treating apparatus. The substrate treating apparatus includes a process chamber providing an inner space in which a substrate is treated, a substrate support member disposed within the process chamber to support the substrate, a showerhead disposed to face the substrate support member and partitioning the inner space into an upper space and a lower space, the showerhead having a plasma supply hole through which the upper space and the lower space communicate with each other, an excitation gas supply unit supplying an excitation gas into the upper space, a process gas supply unit supplying a process gas into the lower space, and a microwave apply unit applying a microwave into the upper space.
