    • The present invention relates to a method of forming an ohmic electrode in a semiconductor light emitting element, comprising: forming a semiconductor layer having a light emitting structure on a substrate, sequentially laminating a bonding layer, a reflective layer and a protective layer on the semiconductor layer, and forming an ohmic electrode by performing a heat treatment process to form ohmic bonding between the semiconductor layer and the bonding layer and to form an oxide film on at least a portion of the protective layer; and a semiconductor light emitting element using the ohmic electrode. According to the present invention, since a reflective layer is formed of Ag, Al and an alloy thereof with excellent light reflectivity, the light availability is enhanced. Further, since contact resistance between a semiconductor layer and a bonding layer is small, it is easy to apply large current for high power.
    • 本发明涉及一种在半导体发光元件中形成欧姆电极的方法,包括:在衬底上形成具有发光结构的半导体层,在半导体上依次层叠结合层,反射层和保护层 并通过进行热处理工艺形成欧姆电极,以在半导体层和接合层之间形成欧姆接合,并在保护层的至少一部分上形成氧化膜; 以及使用欧姆电极的半导体发光元件。 根据本发明,由于反射层由具有优异的光反射率的Ag,Al及其合金形成,所以光可用性得到提高。 此外,由于半导体层和接合层之间的接触电阻小,因此容易施加大电流用于大功率。

    • Provided is an integrating receiver having an adaptive decision feedback equalizer function and a system having the same. The integrating receiver can simultaneously remove an inter-symbol interference (ISI) and high frequency noises in a high speed DRAM data transmission system. The integrating receiver reduces a probability of wrong decision of data in a state in which the ISI that exists in a channel is removed so as to increase a signal-to-noise ratio (SNR) of a receiver, so that a maximum operation speed increases even in an environment with heavy noises. There is also provided a method of obtaining an equalizer coefficient suitable for the integrating receiver and a method of obtaining a reference voltage by using an integrator in a single ended transmission method. In addition, in order to increase a decision feedback equalizer speed, a look-ahead method is used. In this method, flip flops with a high speed including multiplexers are used. Accordingly, the present invention can be applied to not only a DRAM interface system but also a serial communication between chips.
    • 提供一种具有自适应判决反馈均衡器功能的积分接收器和具有该自适应判决反馈均衡器功能的系统。 积分接收器可以同时消除高速DRAM数据传输系统中的符号间干扰(ISI)和高频噪声。 积分接收器在存在于信道中的ISI被去除的状态中降低数据错误判定的可能性,以增加接收机的信噪比(SNR),从而最大运算速度增加 即使在噪音很大的环境中也是如此。 还提供了一种获得适合于积分接收器的均衡器系数的方法以及通过使用单端传输方法中的积分器来获得参考电压的方法。 另外,为了增加判定反馈均衡器的速度,使用先行方法。 在这种方法中,使用包括多路复用器的具有高速度的触发器。 因此,本发明不仅可以应用于DRAM接口系统,还可以应用于芯片之间的串行通信。
