초록

Indium tin oxide (ITO) thin films have been deposited onto bare glass substrates by sol-gel process. The solution was prepared by mixing indium precursor and tin precursor dissolved in 2-methoxyethanol at $75^{\circ}C$ for 12 hours. Indium tin oxide films were prepared by slowly heat up to $200^{\circ}C$ for 10 minutes and annealed at $350^{\circ}C$ for 1 hour. In this paper, we researched simple and inexpensive sol-gel process. To find the optimal ratio of In/Sn to reduce electric resistance in ITO made by sol-gel process, we assessed electric properties varying the ratio of In and Sn precursor.
