Abstract: To provide technology that enables high-frequency power or high-frequency bias power corresponding to the potential of a circuit board in a plasma treatment device to be controlled.SOLUTION: A plasma treatment device that is disclosed comprises a chamber, a circuit board support, a high-frequency power supply, a bias power supply, a measurer, and a control unit. The high-frequency power supply supplies high-frequency power to the lower electrode or upper electrode of the circuit board support provided inside of the chamber. The bias power supply supplies high-frequency bias power to the lower electrode. The measurer measures the frequency of reflected wave of the high-frequency power returned to the high-frequency power supply. The control unit adjusts the power level of the high-frequency bias power according to the peak value of the absolute value of a negative shift amount of reflected wave frequency relative to the frequency of the high-frequency power. Alternatively, the control unit modulates the high-frequency power within a period specified from the peak appearance timing of the absolute value of a negative shift amount of reflected wave frequency relative to the frequency of the high-frequency power.SELECTED DRAWING: Figure 1
