5. 발표내용요약(Abstract)

  Current state of the art process technologies of nanoimprint lithography and its application to photonic devices such as light emitting diodes and photovoltaic devices are presented. Using nanoimprint lithography, a few tens to several hundred nanometer sized patterns of functional materials, including polymer, ITO, ZnO. TiO2,and nano-silver,can be easily for medon various substrates. Conventional polymer resin, along with sol-gel solution, nano-particle dispersed ink was used as an imprint resin. As a substrate, Si wafer, glass plate, flexible polymer films and non-flat surfaced lenz were used. Nano-patterns of functional materials were formed directly on the surface of light emitting diode wafers and solar cells. As a result, the performance of those devices was greatly improved by inserted nano-structures. Air pressed nanoimprint system was used for these study. In this seminar, various process of nanoimprint lithography and its application to solar cells were presented.
