Abstract:
The present invention relates to a control method of a dry etching apparatus which can be applied regardless of materials. The control method of a dry etching apparatus may include: a work piece positioning step of positioning a work piece close to a surface of a cathode unit, facing an anode unit; a bidirectional voltage source applying step of applying a voltage to the cathode unit, the voltage having a polarity alternating between a positive voltage and a negative voltage with time; and an etching step of etching the surface of the work piece using plasma generated by the bidirectional voltage source applied to the cathode unit.

Claim (Index 6):
The control method of  claim 4 , further comprising a DC voltage applying step of applying a DC voltage to the anode unit, after or at the same time as the bidirectional voltage source applying step.
