摘要:
The method of the present invention for forming a monomolecular membrane on a substrate comprises the steps of (1) mixing (a) at least one substance having a water-soluble polar head (hydrophilic portion) and a water-insoluble organic tail (hydrophobic portion) in the molecule, the head being ionizable into a cation when spread on water, and (b) at least one substance having a water-soluble polar head (hydrophilic portion) and a water-insoluble organic tail (hydrophobic portion) in the molecule, the head being ionizable into an anion when spread on water, to obtain a mixture, (2) developing the mixture on an aqueous subphase to form a monomolecular layer, and (3) transferring the monomolecular layer to a substrate while applying a surface pressure to the layer. According to the present invention, there can be formed a unidimensionally controlled membrane which develops a higher function than do the conventional two-dimensionally controlled membranes. Consequently, the method of the present invention can be applied, for example, to the formation of wiring patterns of a molecular level.

A monomolecular polymer film or a lamination of monomolecular polymer films having polyacetylenic, polydiacetylenic, or polyacenic bonds is provided. The film or the lamination is prepared by the use of a chemical adsorbent having at least one triple bond, and a -SiCI group at one molecular end. The chemical adsorbent is adsorbed on a base plate and the polymerization is carried out by the predetermined method. particularly, a highly oriented polymerized monomolecular film or a lamination is prepared by the use of e.g., the STM writing technique or the rubbing process.

Disclosed is a pattern forming method wherein (i) an organic thin film is formed on a semiconductor substrate, (ii) this organic thin film is selectively exposed with a first deep UV light (excimer layer light of 248 nm) to degenerate only the vicinity of the surface of the organic thin film (where the degenerated part possesses the property for absorbing the wavelength of the light of second exposure), (iii) the entire surface of the organic film is irradiated with a light having a waveform with excellent transmissivity of the organic thin film (e.g. g-ray of 436 nm), and (iv) the organic thin film is developed and removed except for the part degenerated by the first exposure, thereby forming a pattern. According to this method, fine processing in fabrication of semiconductor device of the like can be effected easily, and, still more, a superfine pattern (e.g. 0.5 µm or less) can be presented.

The present invention relates to an electrical material and optical material. It relates to a process for producing an organic material having polyacetylene linkages which exhibits electric conductivity and non-linear optical effect. In more articular, the polyacetylene according to the present invention is in the form of organic thin film and is characterized in that, in forming the organic thin film by use of the Langmuir-Blodgett method or a chemical adsorption method, an electric or magnetic field is applied to enhance the orientation of the molecules constituting the organic thin film. It is further characterized in that, also in forming polyacetylene by irradiating an energy beam to the acetylene groups of the molecules constituting the organic thin film, an electric or magnetic field is applied to enhance orientation. The present invention thus provides a process for producing a material which can be used as an electrical material and optical material.

A device substrate comprising a substrate having a flow channel of a liquid, wherein an internal surface of said flow channel has an area non-compatible with said liquid; said area non-compatible with the liquid is formed by a monolayer non-compatible with said liquid; and said monolayer is connected to said substrate via a covalent bond, which allows smooth flow of the liquid in the minute flow channel.
摘要:
A substrate for use in crystallization has a base member, and an organic molecular film on a surface of the base member. The organic molecular film has non-affinity to a liquid, and the surface of the base member and the organic molecular film are covalently bound to each other. The substrate formed with the organic molecular film having non-affinity to the liquid on the surface of the base member is produced by contacting the surface of the base member having an active hydrogen atom or the surface of the base member to which the active hydrogen atom is introduced, with an organic molecule including a terminal-bonding functional group capable of covalently bonding to the surface of the base member at one end thereof, and a functional group showing non-affinity to the liquid at the other end thereof so as to covalently bond the terminal-bonding functional group of the organic molecule to the active hydrogen atom on the surface of the base member by reaction of the terminal-bonding functional group with the active hydrogen atom. The substrate enables to efficiently crystallize polymeric compounds including biomolecules such as proteins, nucleic acids, and sugars; and resins, as well as other organic compounds, and inorganic compounds.
