  • Publication number: 20100147464
    Abstract: The present invention relates to a plasma treatment apparatus for treating an object to be treated by activating a plasma production gas by an electric discharge, and by blowing this activated plasma production gas onto the object to be treated. A covered electrode is formed by embedding a conductive layer in an insulating substrate made of a ceramic sintered body. The covered electrodes are arranged opposed to each other to form an electric discharge space in a space between the covered electrodes. A power supply is included for causing an electric discharge in the electric discharge space by applying a voltage to the conductive layers. Since no ceramic material is sprayed, it is possible to reduce the costs of the material for the covered electrodes, and to simplify the process for manufacturing the covered electrodes.

  • Patent number: 7543546
    Abstract: A plasma treatment apparatus is provided, which enables to increase a treatment area and provide good treatment uniformity. This apparatus comprises a pair of electrode plates having a plurality of through holes and an insulating plate having a plurality of through holes. The insulating plate is disposed between the electrode plates such that positions of the through holes of the electrode plates correspond to the positions of the through holes of the insulating plate. A plurality of discharge spaces are formed by the through holes of the electrode plates and the through holes of the insulating plate. By applying a voltage between the electrode plates, while supplying a plasma generation gas into the discharge spaces, plasmas are generated simultaneously in the discharge spaces, and sprayed on an object to efficiently perform a large-area, uniform plasma treatment.
