    摘要： A semiconductor device with a memory unit of which the variations in the operation timing are reduced is provided. For example, the semiconductor device is provided with dummy bit lines which are arranged collaterally with a proper bit line, and column direction load circuits which are sequentially coupled to the dummy bit lines. Each column direction load circuit is provided with plural NMOS transistors fixed to an off state, predetermined ones of which have the source and the drain suitably coupled to any of the dummy bit lines. Load capacitance accompanying diffusion layer capacitance of the predetermined NMOS transistors is added to the dummy bit lines, and corresponding to the load capacitance, the delay time from a decode activation signal to a dummy bit line signal is set up. The dummy bit line signal is employed when setting the start-up timing of a sense amplifier.

    摘要： The present invention provides a semiconductor laser realizing reduced possibility that a wiring layer disposed in the air is broken even under severe environment of a large temperature difference. A trench is provided between adjacent ridges, and a wiring layer electrically connecting an upper electrode and a pad electrode is disposed in the air at least above the trench. The wiring layer in a portion above the trench has a flat shape or a concave shape which dents toward the trench.
