Abstract

A plasma treatment apparatus for plasma treating an object to be treated or workpiece by exposure to ions, free radicals and activated gas species generated by a plasma discharge includes a suscepter electrode supposing the workpiece and another electrode facing the suscepter electrode, together constituting a pair of plasma generating electrodes across which an AC voltage is applied. The apparatus also includes halogen lamps which are disposed outside of the respective electrodes for radiating heat rays to the object. The plasma generating electrodes are formed of a material which transmits the heat rays from the halogen lamp and resists a temperature of about 200.degree. C. or higher, such as a doped silicon in which impurities are doped into a silicon substrate. Thus, the object may be treated in a short time and at a low temperature by heating and using a plasma.
