Claim 0:
1. A method of forming a wire at predetermined positions of an object, the wire having a nanometer-sized diameter or a micrometer-sized diameter, the method comprising:
preparing a pipette having a tip with an inner diameter, wherein the inner diameter of the tip is a nanometer-sized inner diameter or a micrometer-sized inner diameter;
filling the pipette with a solution containing a wire-forming material;
bringing the solution into contact with an object through the tip of the pipette; and
pulling the pipette apart from the object at a pulling speed lower than or equal to a predetermined critical speed (νc) to obtain a wire having a nanometer-sized diameter or a micrometer-sized diameter,
wherein the critical speed (νc) is a maximum limit of the pulling speed at which the wire to be formed has a same diameter as the inner diameter of the tip of the pipette, and when the pulling speed is lower than the critical speed, the wire has substantially a same diameter as the inner diameter of the tip of the pipette, and when the pulling speed is higher than the critical speed, the wire has a diameter different from the inner diameter of the tip of the pipette.
