    • Disclosed is a method of manufacturing an organic light emitting device, which comprises the steps of successively stacking a bottom electrode, an organic layer including an emission layer, and a top electrode, the method further comprising the step of: surface-treating the bottom electrode with ion beam etching before stacking the organic layer. By effectively removing impurities such as polymer materials or oxidation films, which are formed on the bottom electrode of the organic light emitting device, not only electron injection and hole injection in the organic light emitting device progress smoothly, but also an operation voltage is lowered and performance reliability can ensured because the surface roughness of the bottom electrode is maintained at the same level before and after ion milling.
    • 公开了一种制造有机发光器件的方法,其包括以下步骤:连续堆叠底电极,包括发射层的有机层和顶电极,所述方法还包括以下步骤:对所述底电极进行表面处理 在堆叠有机层之前进行离子束蚀刻。 通过有效地除去形成在有机发光器件的底部电极上的诸如聚合物材料或氧化膜的杂质,不仅有机发光器件中的电子注入和空穴注入进行顺利,还降低了操作电压, 由于底电极的表面粗糙度在离子研磨前后维持在相同的水平,所以可确保性能的可靠性。

    • Provided are a tunable inter-digital capacitor (IDC) and a method of manufacturing the same. The tunable IDC includes: a first dielectric layer formed on a substrate and having electrode pattern grooves of an IDC including a ground line and a signal line formed therein; electrode metal patterns formed in the electrode pattern grooves of the IDC including the ground line and the signal line formed in the first dielectric layer; and a second dielectric layer formed on an upper surface of the first dielectric layer to cover all of the electrode metal patterns except for parts of the ground and signal lines. Therefore, it is possible to increase tunability of the IDC and reduce drive voltage.
