  • Low work function alkali metals and alkaline earths successfully lower the electron injection barrier and increase electron injection into the organic layer in OLED displays, but their implementation is not easy. AlkaMax technology can ensure the required metal evaporation rate in a fast, homogeneous and easily controllable way.

  • Electron injection improvement in OLED organic layers can be obtained by their doping or using alkaline-earth or alkali metals as electron injection layers (EIL). Common handling problems can be solved by an innovative metal dispensing technology to ensure controlled and reliable metal layers for OLED. Thickness and deposition rate of EIL during the process have been explored to optimize device performances.

  • The key role of MgO is well recognized in PDP's technology. During manufacturing, significant contamination of the oxide occurs. Getters can compete against the impurities sorption speed of the oxide layer. The analysis of the impact of a suitable getter configuration on the operational parameters of PDP's is the final goal of this study.

  • In this paper we investigate, on the basis of experimental data, the correlations between contamination issues occurring during production process steps and final PDP operational parameters: these reciprocal relations are the result of dynamic equilibria established within the PDP system, amongst residual gases and sorbed species interacting with heat, ions and photons.

  • For a high efficient field emission display (FED), the specific vacuum conditions below 10-7 Torr should be required. However, because the FED has the geometrical restriction due to its micro size, the thin film getters can be proposed for chemical pumping as a way to reduce impurity gases in the panel. The thin film getters, developed by employing the coating of new materials such as NI or Pt on getter surface, can be used without any activation process and show the enhanced sorption characteristics. Especially, using the Zr (1${\mu}{\textrm}{m}$) thin film getters with the Pt surface layer, the significant gettering for various active gases could be achieved from 9$\times$10-5 Torr to 1$\times$10-6 Torr or below. this good sorption properties is mainly contributed to the surface coating layer which shows the catalytic effect for gas dissociation and protects the getter materials against oxidation.

  • 이온 펌프의 중심에 네그(Non-Evaporable Getters)가 삽입된 새로운 조합 펌프를 사용하여 극고진공 시스템을 구현하였다. 진공 용기는 터보 분자 펌프만으로도 극고진공에 성공하였던, $450^{\circ}C$에서 잘 산화된 304 스테인레스 스틸 쳄버를 사용하였다. 시스템의 압력은 Leybold사의 EXG(Extractor Gauge)로 측정하였으나, 본 실험에서의 최고 진공도는 이미 그 게이지의 측정 한계인 1~$2\times10^{-12}$torr범위를 훨씬 지나 게이지 지시가 $-0\times10^{-12}$torr를 읽교 있는 극고진공에 도달해 있었다. 이는 효과적인 네그 활성화로 수소 가스에 대한 배기 속도 를 크게 향상시켜준 결과라 볼 수 있다. 또한 본 실험은 극고진공 표면 분석 장치의 실현 가능성을 시사해주는 것으로, 앞으로의 초미세 표면 과학에 있어서 새로운 장을 열어줄 것 으로 기대된다.
