Abstract
A high frequency generator having dual outputs comprises: a high frequency amplifying unit configured to amplify a DC voltage of a predetermined level, and output a first and a second high frequency amplification signal; a combiner configured to combine the first high frequency amplification signal and the second high frequency amplification signal, and output a high frequency power signal; a high frequency sensor disposed on output side of the combiner, configured to detect an electrical signal flowing the output side of the combiner, and output an electrical detection signal; a controller configured to output multiple control signals by using an externally applied control signal and the electrical detection signal; and a switching unit disposed between the combiner and the plasma chamber, and controlled by a switching control signal outputted from the controller to output the high frequency power signal to a first high frequency power output signal through a first output terminal and to output the high frequency power signal to a second high frequency power signal through a second output terminal.
