    摘要: A stack-type capacitor includes a lower electrode, a dielectric layer formed on the lower electrode, and an upper electrode formed on the dielectric layer, wherein the lower electrode includes a first metal layer having a cylindrical shape and a second metal layer filled in the first metal layer. In the capacitor, an amount of oxygen included in the lower electrode is decreased to suppress oxidation of a TiN layer. Thus, a stable stack-type capacitor may be formed, which increases greatly the performance of highly integrated DRAMs.

    摘要: A mixed dispersant which can improve the efficiency of dispersing metal powder by effectively adsorbing on the surface of the metal powder and preventing aggregation thereof, and a paste composition and a dispersion method using the same are provided. A multilayer ceramic capacitor (MLCC) is also provided. The mixed dispersant includes a basic dispersant and an acidic dispersant in accordance with the acidity and basicity of nickel metal powder and thus can achieve an optimal dispersion efficiency. An improvement in the dispersion efficiency as such can consequently suppress aggregation of the nickel metal powder during the preparation of a conductive paste composition containing a nickel metal powder, and therefore a larger amount of the nickel metal powder can be used in the paste composition. The increased amount of nickel metal powder allows producing an internal nickel electrode having improved electric properties and mechanical properties during the production of MLCCs.

    摘要: Provided are non-magnetic nickel powders and a method for preparing the same. The nickel powders are non-magnetic and have a HCP crystal structure. An exemplary method includes (a) dispersing nickel powders with a FCC crystal structure in an organic solvent to prepare a starting material dispersion, and (b) heating the starting material dispersion to transform the nickel powders with the FCC crystal structure to the nickel powders with the HCP crystal structure. The nickel powders do not exhibit magnetic agglomeration or aggregation phenomenon. Therefore, exemplary pastes for inner electrode formation in various electronic devices, which contain the nickel powders of the present disclosure, can be provided in a relatively uniform, well-dispersed state because of the reduced aggregation and agglomeration of the nickel powder. Also, inner electrodes made of the nickel powders can have a low impedance value even at high frequency band.

    摘要: A photo-luminescent (PL) liquid crystal display (LCD) including a blue dichroic mirror layer disposed under a light emitting layer is provided. Visible light generated from the light emitting layer is mostly reflected to the front side of the PL LCD, thereby increasing the light utilization efficiency thereof. A blue PL quantum dot layer is formed in blue light regions, thereby improving a narrow viewing angle and an orientation in blue pixels. An ultraviolet (UV) filter blocking UV light in the ambient light is formed to protect the light emitting layer from the excitation caused by external light, thereby preventing degradation of contrast caused by an undesired light emission.
