  • Patent number: 8791020
    Abstract: A pattern-forming method includes forming a silicon-containing film on a substrate, the silicon-containing film having a mass ratio of silicon atoms to carbon atoms of 2 to 12. A shape transfer target layer is formed on the silicon-containing film. A fine pattern is transferred to the shape transfer target layer using a stamper that has a fine pattern to form a resist pattern. The silicon-containing film and the substrate are dry-etched using the resist pattern as a mask to form a pattern on the substrate in nanoimprint lithography. According to another aspect of the invention, a silicon-containing film includes silicon atoms and carbon atoms. A mass ratio of silicon atoms to carbon atoms is 2 to 12. The silicon-containing film is used for a pattern-forming method employed in nanoimprint lithography.

  • Patent number: 8771455
    Abstract: Provided is a process for production of composite fine particles with heterogeneous surfaces. The process ensures a high productivity and enables a voluntary control of particle diameters. Further, the process imposes no restrictions on heterogeneous substances added for functional expression, and allows a heterogeneous substance to be encapsulated in central portions of composite fine particle spheres. A composite film obtained by laminating two or more kinds of films is cut into minute pieces, followed by melting the same to obtain spherical minute pieces. Particularly, liquid films are separately formed with two or more kinds of liquids containing polymerizable monomers. Further, two or more kinds of films can thereby be obtained through polymerization. The two or more kinds of films thus obtained are then laminated to further allow polymerization to take place, thus obtaining the composite film.
