Abstract: The present invention provides a method of fabricating a light emitting diode chip having an active layer between an N type semiconductor layer and a P type semiconductor layer. The method comprises the steps of preparing a substrate; laminating the semiconductor layers on the substrate, the semiconductor layers having the active layer between the N type semiconductor layer and the P type semiconductor layer; and forming grooves on the semiconductor layers laminated on the substrate until the substrate is exposed, whereby inclined sidewalls are formed by the grooves in the semiconductor layers divided into a plurality of chips. According to embodiments of the present invention, a sidewall of a semiconductor layer formed on a substrate of a light emitting diode chip is inclined with respect to the substrate, whereby its directional angle is widened as compared with a light emitting diode chip without such inclination. As the directional angle of the light emitting diode chip is wider, when a white light emitting device is fabricated using the light emitting diode chip and a phosphor, light uniformity can be adjusted even though the phosphor is not concentrated at the center of the device. Thus, the overall light emitting efficiency can be enhanced by reducing a light blocking phenomenon caused by the increased amount of the phosphor distributed at the center portion.

Abstract translation: 本发明提供一种制造在N型半导体层和P型半导体层之间具有有源层的发光二极管芯片的方法。 该方法包括以下步骤：制备基底; 在所述基板上层叠所述半导体层，所述半导体层具有在所述N型半导体层和所述P型半导体层之间的有源层; 以及在层叠在基板上的半导体层上形成凹槽，直到基板被暴露，由此通过划分成多个芯片的半导体层中的凹槽形成倾斜的侧壁。 根据本发明的实施例，形成在发光二极管芯片的基板上的半导体层的侧壁相对于基板倾斜，由此与没有倾斜的发光二极管芯片相比，其方向角度变宽。 随着发光二极管芯片的方位角变宽，当使用发光二极管芯片和荧光体制造白色发光器件时，即使荧光体不集中在器件的中心，也可以调整光均匀性。 因此，通过减少由分散在中心部分的荧光体的量增加引起的遮光现象，可以提高整体发光效率。

Abstract: An adaptive writing method of a high-density optical recording apparatus and a circuit thereof. The circuit includes a discriminator for discriminating a magnitude of a present mark of input NRZI data and magnitudes of leading and/or trailing spaces of the input NRZI data, a generator for controlling the waveform of a write pulse in accordance with the magnitude of the present mark of the input NRZI data and the magnitudes of the leading and/or trailing spaces of the input NRZI data to generate an adaptive write pulse, and a driver for driving a light source by converting the adaptive write pulse into a current signal in accordance with driving power levels for respective channels of the adaptive write pulse. The widths of the first and/or last pulses of the write pulse waveform are varied in accordance with the magnitude of the present mark of input NRZI data and the magnitude of the leading and/or trailing spaces, thereby minimizing jitter to enhance system reliability and performance.

Abstract: A dual-band antenna for mobile communication unit is provided with a support made of an insulating material, double stranded helical conductors, and a coaxial feeder connected to an end of each of the helical conductors. The double stranded helical conductors are wound in an identical direction on the support without intersecting each other to have different resonance frequencies, respectively, a winding region of the second helical conductor being a part of that of the first helical conductor. When a voltage is applied to the first and the second helical conductors through the coaxial feeder, the antenna operates in the optimum performance at two frequency bands. As a result, the unit can use a desired different mobile telecommunication service without changing it. Further, the inventive antenna is designed to be small in size to thereby allow it to be adapted on the mobile telecommunication unit.
