Method of fabricating optical aperture and method of fabricating probe for near field light device

摘要

The problem of the invention is to provide a method of forming an optical aperture constituting a source of generating and detecting near field light. Hence, according to a method of fabricating an optical aperture of the invention, a face of a pushing body is made to be opposed to an object for aperture formation having a tip of a conical or a pyramidal shape formed at a substrate, a stopper arranged at a vicinity of the tip and a optical shielding film formed at least above the tip to cover at least a portion of the stopper and the tip and the pushing body is pushed to the object for aperture formation by force having a component directed to the tip to thereby form the optical aperture at the front end of the tip.
