Patent ID: 7814648

Claim:
A method of disposing an electronic device on an electrode formed on a substrate to connect electrically the electronic device and the electrode, the method comprising: a pre-step of preparing a substrate having on a surface on which a hydrophilic region surrounded by a water-repellent region, the hydrophilic region being provided with a hydrophilic electrode; a first step of applying an electroless plating solution in which a metal compound is dispersed in water to the substrate to dispose the electroless plating solution in the hydrophilic region; a second step of applying an electronic device-dispersed liquid in which an electronic device is dispersed in a first liquid to the substrate to move the electronic device from the first liquid to the electroless plating solution, the electronic device having a device electrode that is provided at a position corresponding to the hydrophilic electrode so as to come into contact with the hydrophilic electrode, the hydrophilic electrode being in contact with the device electrode, a surface of the electronic device having hydrophilicity, the first liquid being an organic solvent having no compatibility with the electroless plating solution, and one of surfaces of the electronic device that is to be bonded to the hydrophilic region having the same shape and size as the hydrophilic region of the substrate; a third step of coating a surface of the substrate with a second liquid before the water contained in the electroless plating solution volatilizes completely to cause a plating reaction between the hydrophilic electrode and the device electrode and to connect electrically the hydrophilic electrode and the device electrode, the second liquid being an organic solvent having no compatibility with the electroless plating solution; and a fourth step of removing the second liquid from the substrate.
