Abstract:
A micro-processing method for forming an electroconductive micro-region surrounded by a non-electroconductive region on a non-electroconductive substrate, comprising the steps of:moving a probe having a micro-aperture for irradiation of light to a spot to be processed on said substrate, said micro-aperture having a size smaller than a wavelength of light to be used for irradiation, wherein said light is evanescent light;irradiating a non-electroconductive thin film formed on said non-electroconductive substrate with light through the micro-aperture of the probe; andforming an electroconductive micro-region confining electrons therein by altering the electroconductivity of said non-electroconductive thin film.
