Patent ID: 8413576

Claim:
A method of fabricating a structure, the method comprising: forming a first layer over a substrate; forming a second layer over the first layer; embossing the second layer to form a protrusion and an indentation in the second layer, a thickness of a portion of the second layer at the protrusion being larger than a thickness of a portion of the second layer at the indentation; etching the first layer and the second layer to remove at least a part of the second layer, and a part of the first layer corresponding to the indentation of the second layer to form an indentation and a protrusion in the first layer, whereby the indentation in the second layer is substantially removed, the first and second layers forming a bank structure; treating the bank structure to increase the degree of lyophobicity of a side surface of bank structure in the first layer; removing the second layer from the substrate; disposing a functional liquid on the top surface of the protrusion of the first layer; subsequently removing the indentation in the first layer to expose a surface of the substrate; treating the bank structure to increase the lyophilicity of the surface of the substrate and to increase the lyophobicity of a side surface of the protrusion; disposing the functional liquid between side surfaces of the bank structure in a region corresponding to the indentation in the first layer after treating the surface of the substrate; and forming electronic circuitry with the functional liquid.
