Patent ID: 8163329

Claim:
A method for mounting a component on a substrate, the method comprising steps of: a step of preparing a hydrophilic first liquid; a step of preparing a component-dispersing liquid where the component is dispersed in a second liquid, the second liquid being insoluble in the first liquid, and at least one surface of the component being hydrophilic; a step of preparing the substrate comprising a hydrophilic region and a water-repellant region, wherein: the water-repellant region surrounds the hydrophilic region, the water-repellant region comprises a surface coated with a fluorine compound, the hydrophilic region comprises a component-mounting region having a shape congruent or similar to that of a bottom surface of the component and a liquid-capturing region formed on a periphery of the component-mounting region, the surface of the liquid capturing region is formed by the reaction of a material represented by the chemical formula: X—(CH 2 ) n —Si—Y 3 with the surface of the substrate, where X represents N + R 3 Q − (Q represents Cl, Br, or I), OR, or halogen atom, R represents lower alkyl group with a carbon number of 1-4, n represents a natural number of not less than 1 and not more than 3, Y is an alkoxy group or a halogen, a contact angle of the liquid-capturing region is greater than that of the component-mounting region, and the contact angle of the liquid-capturing region is less than that of the water-repellant region; a step of disposing the first liquid to the hydrophilic region; a step of bringing the component-dispersing liquid in contact with the first liquid disposed on the hydrophilic region; and a step of removing the first liquid and the second liquid from the substrate to dispose the component on the hydrophilic region.
