  • Tin doped $In_2O_3$ sputtering target is widely used to produce a various kinds of flat panel display because of high transmittance in visible region and high electrical conductivity. In2O3 and SnO2 powders were prepared by a homogeneous precipitation method using metal source, respectively, the calcining and sintering behavior of the indium-tin oxide(In2O3-SnO2) composite powders were studied. The tin oxide(SnO2) dispersion condition in ITO sputtering target was improved by increasing calcining temperature. And the tin oxide dispersion was also improved by reducing the tin oxide contents in the ITO target from 30 to 5wt%. SnO2 dispersion and densification of ITO target is very difficult to control due to sublimation of SnO2 at over 1150C.

  • In this study, we report on the characteristics of Aldoped ZnO (AZO) co-sputtered indium tin oxide (ITO) films prepared by dual target direct current (DC) magnetron sputtering at room temperature for organic light emitting diodes (OLEDs). The electrical and optical properties of co-sputtered IAZTO electrode were critically dependent on the DC power of AZO. Furthermore, the characteristics of co-sputtered IAZTO electrode were influenced by rapid thermal annealing temperature.

  • In this paper, we have studied about the optimum fabrication condition of the printed Indium Tin Oxide (ITO) layers for the electrical resistance-type sensor application. We have investigated on the substrates surface treatments, mixing ratio of organic binder/ITO powder, and viscosity of the printing paste to determine the optimum condition of the screen printed ITO layer. Also, we found that the printing condition is closely related with the sensor performance. To know the feasibility of printed ITO layer as an electrical resistance-type sensor, we have fabricated the ITO sensors with a printed and sputtered ITO layers. The printed ITO films revealed $10^2$ times higher sensitivity than the sputtered ITO layer. Also, the sputtered ITO layer exhibited an operating temperature of $127^{\circ}C$ at the operating voltage of 5 V. While, in case of the printed ITO layer showed the operating temperature of $27.6^{\circ}C$ in high operating voltage of 30 V. We found that the printed ITO layer is suitable for the various sensor applications.
