EINKRISTALLINE MIKROSPITZE, IHRE HERSTELLUNG UND IHRE ANWENDUNGEN

摘要

A microtip has a tip portion forced by gathering of three crystal faces of a single crystal, at least one of the crystal faces being an etched face at and around the tip portion. The microtip is produced by breaking and splitting a single crystal by giving a stress, and subjecting the face formed by breaking of the single crystal to anisotropic etching by utilizing facial orientation, thus forming a tip portion as a gathering point of three crystal faces of the single crystal. A surface-observing apparatus for observing a surface of a specimen and an information-treating apparatus comprise a tip in proximity to the specimen to be observed or a recording medium, and conduct the surface observation or the writing or reading by using the tip, respectively. <IMAGE>
