Indium Tin Oxide (ITO) has been used widely for transparent conducting thin films. In this work, the feasibility of a laser sintering process to fabricate ITO thin films on flexible substrates is examined. Nanoparticles of ~10 nm were spin coated on a Si wafer and then sintered by a KrF excimer laser. The sintered structure was characterized by scanning electron microscopy. Polycrystalline structures were fabricated by the process without thermally damaging the substrate. The electrical resistivity of the film was reduced to ~ 1/1000 of the initial value. This work demonstrates that nanosecond laser sintering of ITO particles can be a useful tool to fabricate ITO films on various flexible substrates.
