Patent ID: 8394458

Claim:
A method for disposing a component on a substrate, the method comprising steps of: a step (a) of preparing the substrate, a first liquid, and a component-containing liquid, wherein: the substrate comprises a water-repellant region, a hydrophilic region, and a hydrophilic line, the water-repellant region surrounds the hydrophilic region and the hydrophilic line, where Y direction denotes the longitudinal 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 and −X direction denotes the reverse direction of the +X direction, the hydrophilic region and the hydrophilic line are disposed along the +X direction in this order, where D 1 denotes the interval along the +X direction between the hydrophilic region and the hydrophilic line, D 2 denotes the length along the Y direction of the hydrophilic region, D 3 denotes the length along the Y direction of the hydrophilic line and D 4 denotes the width of the hydrophilic line, the value of D 1 /D 2 is not less than 0.1 and not more than 1.2, the value of D 3 is not less than 5 micrometers and the value of D 4 is less than the minimum length of the component, the first liquid is hydrophilic, the component-containing liquid contains the component and a second liquid, the second liquid is insoluble in the first liquid, 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 region, then to dispose the first liquid on the hydrophilic line; a step (c) of bringing the component-containing liquid into 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.
