PURPOSE:To obtain a resin pattern having a high definition and a high etching by forming a sensitive thin film on a substrate and by radiating an energy ray in a state of the pattern, thereby exciting or unexciting a sensitive radical and then reacting the residual sensitive radical with a chemical substance having an active group. CONSTITUTION:The sensitive thin film is formed by reacting a silane surface active agent such as CH2=CH-(CH2)n-Si.Cl3 with SiO2 substrate to form a siloxane binding. When an electron beam is radiated in the state of the pattern, a vinyl group positioned in a radiation part polymerizes to form the resin. While a vinyl group positioned in an unradiation part is treated with sodium hydroxide etc. to bind a hydroxyl group with the vinyl group followed by binding the hydroxyl group with the silane surface active agent. By repeating the above described reaction, the thin film having a desired thickness is formed. Since the thin film having a sensitivity against the energy ray is formed from a monomolecular cumulating film, the very fine pattern is formed.

PROBLEM TO BE SOLVED: To provide a film-forming method based on an LB method by which a uniform alignment film using a helical polyacetylene can be obtained.SOLUTION: The method based on the LB method includes: developing a helical polyacetylene onto a liquid surface; and transferring a monolayer film of the helical polyacetylene formed on the liquid surface onto a substrate to form a film, in which a compressibility P represented by the following formula (1) at a time of the film formation is 1×10m/mN or less: P=(1/(dH/dS))×(1/S) (1), where H represents a surface pressure (mN/m) of the monolayer film of the helical polyacetylene, and S represents an area (m) of the monolayer film of the helical polyacetylene developed onto the liquid surface.

PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube thin film, by which a uniform carbon nanotube thin film can be easily produced regardless of whether each carbon nanotube to be used has a functional group or not; and a method for producing a carbon nanotube thin film, by which the carbon nanotube thin film can be directly formed on the surface of an arbitrary substrate. SOLUTION: The method for producing the carbon nanotube thin film includes a dropping process for dropping a mixed liquid containing carbon nanotubes 2 and an ionic liquid on the liquid surface of a film-forming liquid 4 and spreading the carbon nanotubes 2 on the liquid surface. Preferably, the method for producing the carbon nanotube thin film includes a compressing process for compressing the thin film of the carbon nanotubes 2 spread on the liquid surface in the direction (indicated by the arrow A) parallel to the liquid surface and/or a pulling process for pulling the thin film of the carbon nanotubes 2 spread/compressed on the liquid surface of the film-forming liquid 4.

PROBLEM TO BE SOLVED: To fix amphipathic molecules aligned in the same direction to the bead surface, to manufacture a capillary bead array by arraying beads in a capillary formed on a soft resin or the like, and to thereby provide the capillary bead array having high added value to a user. SOLUTION: Water is poured into a vessel 601 to form a water phase 602, and the beads 604 having respectively a specific gravity larger than that of water and a hydrophilic part 603 on the surface are put into the vessel, and the beads are sunk into the water phase. The amphipathic molecules 608 having respectively both a hydrophilic part 606 and a hydrophobic part 607 are dropped into the water phase, and oil having a specific gravity smaller than that of water is slowly poured into the vessel, to form an oil phase 605 on the water phase. An oil/water interface 609 is formed between the water phase and the oil phase, and a monomolecular film 610 of the amphipathic molecules spread on the oil/water interface is formed. A bead capture device tip 611 is moved over the vessel, and the bead capture device tip is lowered to the water phase and captures a single bead 612 in the water phase; the bead capture device tip is lifted, and thereby the single bead is lifted up to the oil/water interface. A functional group 613 contained in the hydrophilic part on the bead surface is bonded covalently to a functional group 614 included in the hydrophilic part of the amphipathic molecule, and thereby a monomolecular layer 615 of the amphipathic molecules is formed firmly on the bead surface.
