PROBLEM TO BE SOLVED: To enable use as a quantum electrode device such as a single electron transistor. SOLUTION: Nanometer-scale particles 3 of Au, for example, are caused to adhere onto an SiO2 surface layer 1 having receptor sites 4 of a first electric polarity provided by processing with an APTMS solution. The Au particles 3 has a surface charge 5 of the opposite second polarity by surface-absorbed citrate ions, for example. As a result, those particles are attracted to the surface sites on a substrate. The Au particles caused to adhered are released from the substrate sites following that. Those particles move on the substrate and are united to be a low-dimensionally integrated construction. It is possible to produce this integrated construction in an irregular surface part on the surface of the substrate. |
