Description
Summary:The optical and electrical properties were characterized with direct-patternable SnO2 thin film prepared by photochemical metal-organic deposition (PMOD) using photosensitive starting precursors. Fourier transform infrared spectroscopic analysis showed that a complete removal of organic groups was possible by an exposure of spin-coated SnO2 precursor film to UV at room temperature. According to the increase in anneal temperature, i.e., amelioration in the crystallinity and structural homogeneity of SnO2 film, optical transmission and resistivity improved; especially in case of optical transmission, there was also an effect from the decrease in film thickness. Direct-patternable SnO2 film annealed at 800 deg C showed the values of average transmittance in visible region and resistivity as 92.28% and 1.61 X 10-2 Omega cm, respectively.
