Patent ID: 7972931

Claim:
A method of manufacturing thin-film transistors using nanoparticles, comprising the steps of: depositing a buffer layer on a substrate using a hydrophilic material; forming a nanoparticle film on the buffer layer ; sintering nanoparticle films on the buffer layer; forming a source and drain electrodes on the nanoparticle film; forming a gate dielectric film by depositing a dielectric material on the nanoparticle film with the source and drain electrodes formed thereon; and forming a top-gate electrode on the gate dielectric film, wherein the step of forming a nanoparticle film comprises the steps of: preparing a nanoparticle solution by dispersing nanoparticles into a solvent; mixing a precipitating agent with the nanoparticle solution; and depositing the nanoparticle solution containing the precipitating agent on the substrate.
