    • A nitride semiconductor LED improved in lighting efficiency and a fabrication method thereof, in which an n-doped semiconductor layer is formed on a substrate. An active layer is formed on the n-doped semiconductor layer to expose at least a partial area of the n-doped semiconductor layer. A p-doped semiconductor layer is formed on the active layer. A p+-doped semiconductor layer is formed on the p-doped semiconductor layer. An n+-doped semiconductor layer is formed in at least a partial upper region of the p+-doped semiconductor layer via n-dopant ion implantation. The n+-doped semiconductor layer cooperates with an underlying partial region of the p+-doped semiconductor layer to realize a reverse bias tunneling junction. Also, an upper n-doped semiconductor layer is formed on the n+-doped semiconductor layer to realize lateral current spreading. The invention can improve lighting efficiency by using the reverse bias tunneling junction and/or the lateral current spreading.

    • A hydraulic control system of an automatic transmission that precisely control is operating hydraulic pressure supplied to a frictional element during shifting and can eliminate oil leak under a maximum operating hydraulic pressure. The hydraulic control system controls a hydraulic pressure generated by a hydraulic pump to from an operating hydraulic pressure for a frictional element selectively operating at each shift ratio. A hydraulic line is configured such that the operating hydraulic pressure of the frictional element is controlled by a pressure control valve and a switching valve that are controlled by a solenoid valve. An exhaust hydraulic line of the pressure control valve is connected to an exhaust hydraulic line of the switching valve such that the exhaust hydraulic line of the pressure control valve can be controlled by a switching of the switching valve.

    • A nitride semiconductor light emitting device and a method of manufacturing the same are disclosed. The nitride semiconductor light emitting device comprises an n-type nitride semiconductor layer formed on a substrate, an active layer formed on the n-type nitride semiconductor layer, a p-type nitride semiconductor layer formed on the active layer, an undoped GaN layer formed on the p-type nitride semiconductor layer, an AlGaN layer formed on the undoped GaN layer to form a two-dimensional electron gas (2DEG) layer at a bonding interface between the AlGaN layer and the undoped GaN layer, and an n-side electrode and a p-side electrode respectively formed on the n-type nitride semiconductor layer and the AlGaN layer to be connected to each other. As a hetero-junction structure of GaN/AlGaN is formed on the p-type nitride semiconductor layer, contact resistance between the p-type nitride semiconductor layer and the p-side electrode is enhanced by virtue of tunneling effect through the 2DEG layer.

    • A flash memory device and method of erasing flash memory cells thereof are provided. The erase of a cell block unit or a page unit is effected by a word line switch included in a predecoder according to a page erase signal. If the erase is effected in the cell block unit, all word lines of one cell block are made to keep 0V. Meanwhile, if the erase is effected in the page unit, only word lines of a corresponding page are made to keep 0V and the remaining word lines are made floated, so that the erase is not performed. Accordingly, the erase can be carried out in the cell block unit or the page unit. It is thus possible to improve efficiency of data management.
    • 提供了一种闪速存储器件及其擦除闪存单元的方法。 单元块单元或页单元的擦除由包含在根据页擦除信号的预解码器中的字线开关来实现。 如果在单元块单元中进行擦除,则使一个单元块的所有字线保持0V。 同时,如果在页面单元中进行擦除,则仅使对应页面的字线保持0V并且使剩余的字线浮动,使得不执行擦除。 因此,可以在单元块单元或页单元中执行擦除。 因此,可以提高数据管理的效率。
