The method for forming a fine pattern on a substrate disclosed includes a step of preparing a hologram having a pattern, a step of irradiating material waves (de Broglie waves) such as neutral beams, ion beams and electron beams on the hologram, and a step of imaging the pattern on the substrate with the material waves being interfered by passing through the hologram. The light source has a source that emits a beam having a coherent wave front. Since the fine patterns are formed by utilizing the interference of material waves, the minimum processing precision can be enhanced to the extent of the wavelength of the material wave.

A technique of forming an elastic DLC structure having ultra high strength by controlling an amount of focused ion beam current from 0.1 to 10 pA, and a growth rate in the range from 0.6 to 5 μm/min. and by using hydrocarbon gas such as phenanthrene (C14H10) and pyrene (C16H10), as source gas, in an apparatus having a gas nozzle for locally maintaining a higher partial gas pressure near the substrate and a structure for confining the gas on the substrate. In this manner, the elastic DLC having the ultra high strength can be obtained of which a hardness can be controlled in a relatively broader range.

The present invention provides a process for producing a nano-graphite structure having a desired two-dimensional or three-dimensional shape, which process possesses enough potential for ultra-fine processing to allow free selection of the size, shape, and position for the construction therefor; typically a process in which the nano-graphite structure 4 is produced by such a way where a nano-structure amorphous carbon structure 2 formed on a substrate 1 in advance in the shape of a desired ultra-fine steric configuration by a beam-excited reaction is equipped with catalyst metal atoms such as iron contained therein, and when subjecting the steric structure to a low-temperature heat treatment, the structure is converted into the graphite structure 3 through a catalytic thermal reaction by means of the catalyst metal atoms involved therein, while the shape of steric configuration thereof holds.

A method which visualizes the distribution of a local electric field formed near a sample 2 is disclosed. A primary electron beam 1 which passes through the local electric field formed near the sample 2 is deflected by the local electric field, secondary electrons which are generated and emitted from a detection element provided downstream of an orbit of the deflected primary electron beam 1 are detected by a secondary electron detector 6, and an image formed based on the detected signal and a scanning electron beam image obtained by scanning the sample 2 are synthesized thus visualizing the distribution of the local electric field in multiple tones. Due to such an operation, it is possible to provide a method for visualizing the distribution of a local electric field in which the distribution of a local electric field can be obtained in multiple tone and in real time by performing image scanning one time using a usual electron beam scanning optical system.

A carbon nanostructure's geometry and electrical characteristics can be controlled. A method for processing a carbon nanostructure according to the present invention includes the steps of: preparing a carbon nanostructure (e.g., a carbon nanotube) (a CNT preparation step); and exposing the carbon nanotube to an energy beam (e.g., an electron beam) while vibrating the carbon nanotube (an exposure step). This facilitates modifying the carbon nanotube in length and electrical characteristics.

A metal fine particle is adhere to a predetermined location on a substrate. A resist film containing a metallic compound dispersed therein is formed on a substrate (101). A patterning of the resist film is conducted by a lithography. The substrate (101) having the patterned resist formed thereon is heated within an oxygen atmosphere to adhere a metal fine particle (106) to the surface of the substrate (101), while removing the resin in the patterned resist.
