Abstract: A substrate treatment apparatus may include a chucking stage supporting a substrate, a sinusoidal generator supplying a sinusoidal wave to the chucking stage, a non-sinusoidal generator supplying a non-sinusoidal wave to the chucking stage, and a mixer between each of the sinusoidal and non-sinusoidal generators and the chucking stage. The chucking stage may include a chuck body and a plasma electrode in the chuck body. The mixer may include a high pass filter between the sinusoidal generator and the plasma electrode, a low pass filter between the non-sinusoidal generator and the plasma electrode, and a band stop filter between the low pass filter and the plasma electrode.
