    摘要： Disclosed herein is a novel functional diamine compound having a dendron structure, polyamic acid which is produced using functional diamine, aromatic cyclic diamine, aliphatic cyclic acid dianhydride, and aromatic cyclic acid dianhydride, polyimide which is produced by imidizing polyamic acid, and an LC alignment film produced using polyimide. Even if the diamine compound is used in a small amount, it is possible to realize a high pretilt angle, thus the pretilt angle is easily controlled. Therefore, it can be used to produce an LC alignment film using a twisted nematic (TN) mode, in which the pretilt angle of liquid crystal is low, and a vertically aligned (VA) mode, which requires a high pretilt angle of about 90°.

    摘要： Disclosed herein is an LC aligning agent using diamine having dendron side chains. In detail, the present invention relates to a composition for an LC alignment film which employs diamine having dendron side chains to produce polyamic acid, followed by imidization. When the LC alignment film is applied to a liquid crystal display device, high heat resistance, high penetration in a visible ray range, excellent alignment, and a high voltage holding ratio are assured. Even though it contains a small amount of functional diamine, a high pretilt angle can be assured. Thus, the pretilt angle is easily controlled and a vertical aligning force is improved.

    摘要： Disclosed herein are a novel diamine compound having a dendron side chain and a liquid crystal alignment material produced using the diamine compound. Specifically, the diamine compound is used to prepare a polyamic acid, which is then used to produce the liquid crystal alignment material. According to the liquid crystal alignment material, the pretilt angle of a liquid crystal is easy to control, and the alignment properties of a liquid crystal are good. Particularly, since the liquid crystal alignment material shows superior chemical resistance to washing solvents used in LCD panel fabrication processes, it has an advantage in that the alignment properties of a liquid crystal are not degraded even after washing.

    摘要： A capacitor of a memory device is formed on a semiconductor substrate having transistors thereon. A mold layer having holes defined therein is formed on the semiconductor substrate. A catalytic metal layer is formed proximate to a bottom boundary of each hole. Reaction gas is fed to the catalytic metal layer to form carbon nanotubes via a catalytic reaction of the reaction gas by the catalytic metal layer. After forming a lower electrode layer proximate to the bottom boundary and sidewall of each hole and over the carbon nanotubes, a dielectric layer is deposited over the lower electrode layer. Upper electrodes are formed on the dielectric layer to form capacitors electrically connected to the transistors.
