Patent ID: 8414976

Claim:
A method for disposing a component on a substrate, the method comprising: a step (a) of preparing the substrate, a first liquid, and a component-dispersing liquid; wherein: the substrate comprises a water-repellant region and a plurality of hydrophilic regions, the water-repellant region surrounds the plurality of hydrophilic regions; each of the hydrophilic regions comprises a hydrophilic body region and a hydrophilic line, the hydrophilic lines are arranged parallel to one another, where Y direction denotes the parallel direction of the hydrophilic line, Z direction denotes the normal line of the substrate, +X direction denotes the direction orthogonal to both of the Y direction and the Z direction, −X direction denotes the reverse direction of the +X direction, the plurality of hydrophilic regions are arranged along the +X direction and along the Y direction, the hydrophilic line and the hydrophilic body region included in each of the hydrophilic region are arranged along +X direction in this order, the hydrophilic body regions and the hydrophilic lines are arranged along the +X direction alternately, where D 1 denotes the interval along the +X direction between the hydrophilic body region and the hydrophilic line included in each of the hydrophilic region, D 2 denotes the length along the Y direction of the hydrophilic body region, D 3 denotes the length along the Y direction of the hydrophilic line, D 4 denotes the width of the hydrophilic line, D 5 denotes the interval between two adjacent hydrophilic lines arranged along Y direction, a value of D 1 /D 2 is not less than 0.1 and not more than 1.2, a value of D 3 is not less than 5 micrometers, a value of D 4 is less than the minimum length of the component, a value of D 5 is not less than 10 micrometers, the first liquid is hydrophilic, the component-dispersing liquid containing the component and a second liquid, the second liquid is insoluble in the first liquid, and the component has a hydrophilic surface, a step (b) of applying the first liquid to the substrate along the +X direction continuously to dispose the first liquid on the hydrophilic lines and the hydrophilic body regions along the +X direction alternately; a step (c) of bringing the component-dispersing liquid in contact with the first liquid disposed on the hydrophilic region; and a step (d) of removing the first liquid and the second liquid from the substrate to dispose the component on the hydrophilic region.
