Patent ID: 7476559

Claim:
A method for manufacturing a thin film pattern substrate, comprising: forming a hexamethyl disilazane (HDMS) layer on a substrate as an adhesion layer; forming a first domain area by forming a plurality of first banks having a tapered shape that protrude from the substrate on the HDMS layer, the plurality of first banks forming a plurality of first linear patterns; and forming a second domain area by forming a plurality of second banks having a tapered shape that protrude from the substrate on the HDMS layer, the plurality of second banks forming a second linear pattern that is in communication with the plurality of first linear patterns of the first domain area to define a flow path that connects the first domain area and the second domain area; after forming the first banks and the second banks, adding a lyophilic property to first regions between the plurality of first banks and second regions between the plurality of second banks using O 2 plasma; adding a repellant property to the plurality of first banks and the plurality of second banks using CF 4 plasma; infusing a functional liquid by droplet discharge of a plurality of droplets to the first regions between the plurality of first banks of the first domain area, the droplets each having a diameter that is greater than a width between first banks; while infusing the functional liquid by droplet discharge to the first regions, flowing the functional liquid from the first domain area along the flow path and to the second domain area utilizing a surface tension of the functional liquid, a width between the first banks, a width between the second banks, and pressures in the first domain area and the second domain area, said pressures in the first domain area and the second domain area being equal; drying the functional liquid to form a wiring pattern; and removing the banks.
