Abstract: PROBLEM TO BE SOLVED: To provide a method to form periodical arrangement of magnetic nano particles into a layer (which may be a single layer or multilayer) with high regularity and to stabilize the arrangement above described on a substrate. SOLUTION: Magnetic nano particles having substantially uniform diameter are arranged at substantially uniform interval on the surface of a substrate 5. The nano particles consist of a magnetic material selected from a group of elements of Co, Fe, Ni, Mn, Sm, Nd, Pr, Pt and Gd, intermetallic compds. of the above elements, binary alloys of the above elements, ternary alloys of the above elements, Fe oxides containing at least one kind of element above described except for Fe, barium ferrite and strontium ferrite. A wear-resistant coating film is preferably deposited so as to adhere the nano particles to the substrate 5 and to maintain the substantially uniform interval.

Abstract: PROBLEM TO BE SOLVED: To provide a method of assembling an array of particulates or molecules using an atomic force microscope for partitioning a ferro-dielectric magnetic domain. SOLUTION: A ferro-dielectric thin film 12 is attached onto a base board 11 which forms a work to be processed, and patterns are formed on the thin film using atomic force microscope which has an electroconductive probe 13 so that the desired nano-circuit pattern is partitioned. Then a selected region on the thin film is exposed to a solution containing chemical seed(s) to be adsorbed or accumulated selectively under influence of the electrophoretic force.

Abstract: PROBLEM TO BE SOLVED: To form a stratification structure of nano-meter(nm) scale particles by placing a lattice-shaped lattice layer containing deoxyribo nucleic acid(DNA) so as to form a cell of the lattice layer on the surface of a substrate, and arranging a single particle in each cell. SOLUTION: A lattice constant of a stratification structure (a second lattice) of nano-meter scale particles is controlled by a lattice layer coincident in DNA. A DNA lattice (a first lattice) is manufactured using an automatic synthesizing method, this arrangement causes DNA to form a regular arrangement in an opening or a lattice site by self organization so as to include a specific nucleotide base arrangement. Then (a) a substrate 1 having a surface, (b) the lattice- shaped lattice layer containing a DNA segment arranged so as to form a cell of the lattice layer are arranged on the surface of the substrate 1, and (c) at least one particle 3 is placed in each cell. Thus, a stratification structure of nano-meter scale particles can be easily formed.

Abstract: A POROUS, LOW-K DIELECTRIC FILM THAT HAS GOOD MECHANICAL PROPERTIES AS WELL AS A METHOD OF FABRICATING THE FILM AND THE USE OF THE FILM AS A DIELECTRIC LAYER BETWEEN METAL WIRING FEATURES ARE PROVIDED . THE POROUS, LOW-K DIELECTRIC FILM INCLUDES A FIRST PHASE OF MONODISPERSED PORES HAVING A DIAMETER OF FROM ABOUT 1 TO ABOUT 10 NM THAT ARE SUBSTANTIALLY UNIFORMLY SPACED APART AND ARE ESSENTIALLY LOCATED ON SITES OF A THREE-DIMENSIONAL PERIODIC LATTICE; AND A SECOND PHASE WHICH IS SOLID SURROUNDING THE FIRST PHASE. SPECIFICALLY, THE SECOND PHASE OF THE FILM INCLUDES (i) AN ORDERED ELEMENT THAT IS COMPOSED OF NANOPARTICLES HAVING A DIAMETER OF FROM ABOUT 1 TO ABOUT 10 NM THAT ARE SUBSTANTIALLY UNIFORMLY SPACED APART AND ARE ESSENTIALLY ARRANGED ON SITES OF A THREE-DIMENSIONAL PERIODIC LATTICE, AND (ii) A DISORDERS ELEMENT COMPRISED OF A DIELECTRIC MATERIAL HAVING A DIELECTRIC CONSTANT OF ABOUT 2.8 OR LESS.

Abstract: A magnetic storage medium is disclosed which is formed from a layer of substantially uniformly spaced-apart magnetic nanoparticles of substantially uniform diameter disposed upon a surface of a substrate, with a coating, preferably of abrasion-resistant material, applied to adhere the nanoparticles to the substrate and to maintain their substantially uniform spaced-apart relationship. The nanoparticles are formed from a magnetic material selected from the group consisting of elements Co, Fe, Ni, Mn, Sm, Nd, Pr, Pt, Gd, an intermetallic compound of the aforesaid elements, a binary alloy of said elements, a ternary alloy of said elements, an oxide of Fe further comprising at least one of said elements other than Fe, barium ferrite, and strontium ferrite.
