Abstract
A surface processing method for processing the surface of an insulating article in which an ion-implanted surface-modified layer is effectively formed on the article In surface processing the article of an insulating material, an electrically conductive thin metal film is first formed on the article surface. A pulsed voltage containing a positive pulsed voltage and a negative pulsed voltage is applied to the article in a plasma containing ions to be implanted to implant ions in the article surface. This implants ions at right angles to the article surface to generate a surface-modified layer There is no possibility of the article being charged up due to application of a pulsed voltage.
