摘要： There is provided a plasma etching method capable of achieving a sufficient organic film modifying effect by high-velocity electrons. In forming a hole in an etching target film by plasma etching, a first condition of generating plasma within a processing chamber by way of turning on a plasma-generating high frequency power application unit and a second condition of not generating the plasma within the processing chamber by way of turning off the plasma-generating high frequency power application unit are repeated alternately. Further, a negative DC voltage is applied from a first DC power supply such that an absolute value of the applied negative DC voltage during a period of the second condition is greater than an absolute value of the applied negative DC voltage during a period of the first condition.
