The purpose of the present invention is to provide a method for transferring a pattern of a circuit pattern precursor formed of electroconductive particles containing no resin component onto an objective substrate with high transfer efficiency while retaining a pattern shape. A method of transferring the circuit pattern precursor formed from an conductive particle dispersed solution on a dielectric thin film body includes the steps of: temporarily removing a liquid film remaining around the circuit pattern precursor right after a development step; subsequently re-electrifying the electroconductive particle pattern by supplying a solvent again to the circuit pattern precursor; and then electrostatically transferring the pattern onto the objective substrate through electrophoresis in the solvent.

Circuit pattern formation device and method of forming circuit pattern

An object is to improve the adhesion strength between a circuit pattern and its substrate without increasing the resistance value of the circuit pattern in preparation of a circuit pattern holding substrate. A circuit pattern formation deviceforms, after forming a precursor circuit-patternin the surface of a dielectric thin film body, a circuit patternonto a target substratefrom the dielectric thin film body. After forming an electrostatic latent imagein the upper surface of the dielectric thin film body, the electrostatic latent image is exposed using an exposure unitto prepare a pattern. A development apparatussupplies a conductive particle dispersion solutionto this pattern to form a precursor circuit-pattern. By energizing the circuit pattern holding substrate, in which an adhesive layeris formed, the precursor circuit-pattern is temporarily transferred to the circuit pattern holding substrate. The transferred precursor circuit-pattern is heated using the heaterto form a circuit pattern. The circuit pattern and the adhesive layer are released from the circuit pattern holding substrate, thereby transferring to the target substrate.
