    摘要: In controlling a time period of energization of a high pressure electromagnetic valve (50) in accordance with a target value of a fuel injection quantity determined from at least an engine speed (Ne) and an engine load, when a target indicated value (theta) of the time period of energization determined from at least the engine speed and the engine load is lower than a zero indicated value (theta.sub.0) of the time period of energization when the fuel injection quantity becomes zero, which is determined from the engine speed, the energization of the high pressure electromagnetic valve is cut off. Therefore, the duty cycle of the high pressure electromagnetic valve is decreased thereby increasing the reliability of the valve. In addition, fuel is reliably cut off when the fuel injection quantity is 0 mm.sup.3 /st thus avoiding fuel leakage and preventing the generation of white exhaust smoke. Fuel economy can therefore be improved.

    摘要: At least not less than one capacitor formation trench providing an uneven surface is formed on the surface of a capacitor formation region. Thus, the surface area of a capacitor is increased, which enables improvement of the capacitance of the capacitor per unit area. Further, by forming the capacitor formation trench and an element formation trench that are formed in the surface of the semiconductor substrate by the same step, it is possible to simplify the manufacturing process. Whereas, a dielectric film of the capacitor in the capacitor formation region and a high-voltage gate insulating film in a MISFET formation region are formed by the same step; alternatively, the dielectric film of the capacitor in the capacitor formation region and a memory gate interlayer film between a polysilicon layer and a polysilicon layer in the memory cell formation region are formed by the same step.
