— A novel self‐bank method for fabricating a thin‐film metal conductor was studied by drying silver‐nanoparticle dispersion droplets. The bank of the thin‐film metal conductor was created spontaneously utilizing the self‐bank method. A uniform film of polymethyl methacrylate (PMMA) used as a barrier layer was formed on a glass substrate. Silver nanoparticles were dispersed in a suitable solvent for which PMMA is soluable and a silver nanoparticle fluid suspension was formed. When the silver‐nanoparticle fluid suspension was injected into the PMMA film of the substrate, the solvent dissolved the PMMA film, creating a restricted area for silver nanoparticle material defining the bank of the conductive area which improves the uniformity and conductivity of metal film. The metal conductor with a self‐defined bank is formed when the PMMA film was removed after sintering. This self‐bank method would be helpful in improving the deposition process of the functional materials in the fabrication of organic light‐emitting diodes, organic thin‐film transistors, color filters, metal electrodes, and biosensors.
