    • A clock signal supply system is disclosed for a semiconductor device with a semiconductor chip and a wiring substrate connected in flip-chip fashion and an optical waveguide interposed in the space between electrode members, in which the mutual arrangement of the electrical interconnection and the optical waveguide interconnection on the wiring substrate is not affected and can be used separately from each other for different applications, thereby improving the throughput of the interconnections as a whole. In order to distribute a very fast clock signal beyond a 1 GHz in particular without any phase deviation in the clock signal supply system, a clock distributor includes a clock oscillator, a phase adjuster for adjusting the phase at each destination of the clock signal, an optical interconnection for supplying the clock signal to the phase adjuster, a reference signal generator for generating a phase reference signal from the clock signal, and an electrical interconnection for supplying the reference signal to the phase adjuster. The clock signal is supplied by an optical interconnection having a broad frequency bandwidth, and the phase reference signal by an electrical interconnection by which the skew is controlled easily. A clock signal adjusted to high phase accuracy can thus be distributed to following destinations by the phase adjuster.
    • 公开了一种半导体器件的时钟信号供给系统,半导体器件具有以倒装芯片方式连接的半导体芯片和布线基板,以及插入在电极部件之间的空间中的光波导,其中电互连和光波导 布线基板上的互连不受影响,并且可以彼此分开地用于不同的应用,从而提高互连的整体的吞吐量。 为了在非常快的时钟信号中分配非常快的时钟信号,特别是在时钟信号供给系统中没有任何相位偏差,时钟分配器包括时钟振荡器,用于调整时钟信号的每个目的地的相位的相位调节器, 用于向相位调节器提供时钟信号的光互连,用于从时钟信号产生相位参考信号的参考信号发生器和用于将参考信号提供给相位调节器的电互连。 时钟信号由具有宽频带宽的光互连提供,并且相位参考信号由通过电互连的相位参考信号提供,通过该互连可以容易地控制偏斜。 因此,调整到高相位精度的时钟信号可以由相位调节器分配到后续目的地。
