Title METHOD FOR FABRICATING ELECTRODE STRUCTURE HAVING NANOGAP LENGTH, ELECTRODE STRUCTURE HAVING NANOGAP LENGTH OBTAINED THEREBY, AND NANODEVICE
Abstract A substrate (1) on which metal layers (2A, 2B) are disposed with a gap therebetween is immersed in an electroless plating solution in which a reducing agent and surfactant are mixed into an electrolyte containing metal ions. The metal ions are reduced by the reducing agent, and while the metal is deposited on the metal layers (2A, 2B), the surfactant adheres to the surface of the metal, and electrodes (4A, 4B), wherein the gap length is controlled to a nanometer size, are formed. Thus, a method for fabricating an electrode structure having a nanogap gap length such that the variations in gap length can be controlled, an electrode structure having a nanogap length in which variations in gap length are suppressed using this fabrication method, and a nanodevice provided with the same are provided.
Scope of claims [claim1]

(Claims machine translated from Japanese)
[claim2]
1. Metal layer having the gap, the reducing agent and the surface active agent being mixed the baseplate which is arranged in opposite, in the electrolyte which includes the metal ion, the metal ion being restored by soaking in the non electric field plated liquid which becomes, by the above-mentioned reducing agent, while the metal precipitating to the above-mentioned metal layer, the above-mentioned surface active agent coming in contact with the surface of the said metal, production method of the electrode structure which forms the electrode opposite which controls the gap length in nano- meter size, possesses nano- gap length.
[claim3]
2. The 1st step which in the baseplate in order to possess the gap, arranges metal layer in opposite and,
In order for the above-mentioned metal layer to have the gap, the reducing agent and the surface active agent being mixed the baseplate which is arranged in opposite, in the electrolyte which includes the metal ion, the metal ion being restored by soaking in the non electric field plated liquid which becomes, by the above-mentioned reducing agent, while the metal precipitating to the above-mentioned metal layer, the above-mentioned surface active agent coming in contact with the surface of the said metal, the 2nd step which forms the electrode opposite which controls the gap length in nano- meter size and,
Production method of the electrode structure which it includes, possesses nano- gap length.
[claim4]
3. Production method of the electrode structure where the aforementioned surface active agent consists of the molecule which possesses the alkyl chain length which corresponds to the aforementioned nano- gap possesses the nano- gap length of statement in claim 1 or 2.
[claim5]
4. Production method of the electrode structure which controls gap length with the aforementioned surface active agent, possesses the nano- gap length of statement in claim 1 or 2.
