Abstract:
In a plasma processing method, a substrate is loaded onto a substrate electrode within a chamber, the substrate having an object layer to be etched thereon. A plasma generating power output is applied to form plasma within the chamber. A first bias power output is applied to the substrate electrode to perform a first etch stage on the object layer. A second bias power output having a nonsinusoidal voltage waveform is applied to the substrate electrode to perform a second etch stage on the object layer.

Claim (Index 16):
A plasma processing apparatus, comprising;\n a chamber providing a space to process a substrate; a substrate stage configured to support the substrate within the chamber, the substrate stage comprising a substrate electrode; an upper electrode arranged on an upper portion of the chamber to face the substrate electrode; a plasma generating power supply configured to apply a plasma generating power output to the upper electrode in response to a plasma generating power control signal to form plasma within the chamber; a bias power supply configured to selectively apply a first bias power output and a second bias power output to the substrate electrode in response to a bias power control signal, the second bias power output having a nonsinusoidal voltage waveform; and a controller configured to control application of the first and second bias power outputs to the substrate electrode by supplying a bias power control signal corresponding to one of the first and second bias power outputs to the bias power supply.
