    摘要: A direct current pulse voltage is applied on a treatment gas to generate a discharge plasma. The duty ratio of the direct current pulse voltage is controlled within the range of 0.0001% or more and 8.0% or less. The rise time of the direct current pulse voltage is controlled in the range of not lower than 0.1 V/nsec and not higher than 10000 V/nsec. Alternatively, a positive pulse and a negative pulse are applied from a single power source for performing the discharge plasma and the impurity implantation.

    摘要: A pulsed power supply includes a DC power source, and a transformer and a switch which are connected in series with each other across the DC power source. The pulsed power supply operates to produce a plurality of high-voltage pulses in a repetition of cycles in each of which an induced energy is stored in the transformer when the switch is turned on and a high-voltage pulse is generated across a secondary winding of the transformer when the switch is turned off. The current flowing through the primary winding of the transformer is controlled to keep its peak value constant. The pulsed power supply further includes a current detector for detecting the current flowing through the primary winding of the transformer, and a third circuit for turning off the switch when the current detected by the current detector reaches the peak value.

    摘要: Provided is a method of manufacturing a DLC film formed body in which peeling-off of a DLC film is suppressed. In manufacturing a DLC film formed body having a film hardness of 10 GPa or more, prior to the formation of the DLC film, a surface of a base is pretreated with a discharge plasma and a silicon carbide film being an interlayer is formed on the surface of the base. The surface of the base is pretreated by supplying an inside of the chamber with a gas mixture obtained by mixing 1 part by volume or more and 10 parts by volume or less of argon gas into 100 parts by volume of helium gas while adjusting a pressure inside of the chamber in which the base is housed to 20 hPa or higher and an atmospheric pressure or lower, and generating a discharge plasma in the mixed.
