    • A method for fabricating an STI structure in a semiconductor device is disclosed. A disclosed method comprises: forming a pad oxide layer and a pad nitride layer on a substrate in sequence; patterning the pad oxide layer and the pad nitride layer to expose a predetermined part of the surface of the silicon substrate; forming a trench by etching the exposed part of the silicon substrate; depositing a nitride layer inside the trench and on the entire surface of the resulting structure; forming a thin thermal oxide layer along the interface between a silicon substrate and the thin nitride layer; and performing a wet cleaning process to make a predetermined angle in the upper part of the trench.

    • A mobile terminal having a liquid crystal display apparatus, which includes a liquid crystal panel having a polygonal flat shape and an adhesion member installed on at least one part among edges except corner parts at the flat portion of the liquid crystal panel. The mobile terminal includes a transmission and reception unit positioned at one side of a case, an input adjusting unit exposed to external portion of the case, a control unit, and a liquid crystal display driving unit operated by an output signal of the control unit, Accordingly, the mobile terminal with the liquid crystal display apparatus features improved durability and reliability since the liquid crystal panel has minimized spot generation that may occur from physical impacts, temperature changes or applied wrenching loads.
    • 一种具有液晶显示装置的移动终端,其包括具有多边形平面形状的液晶面板和安装在液晶面板平坦部分的角部以外的边缘中的至少一部分上的粘接构件。 移动终端包括位于壳体的一侧的发送和接收单元,暴露于外壳的外部的输入调整单元,控制单元和由控制单元的输出信号操作的液晶显示驱动单元, 因此,具有液晶显示装置的移动终端具有改善的耐久性和可靠性,因为液晶面板具有可能由物理冲击,温度变化或施加的扭转负载引起的最小化的斑点产生。
