A DRAM includes two main column selecting lines provided at each sense amplifier zone, eight sub column selecting lines provided at each sense amplifier zone to correspond to each memory block, two sub decoder column selecting lines provided at each sub decoder zone, a sub column decoder provided at each crossing portion of the sense amplifier zone and the sub decoder zone to select one sub column selecting line from corresponding eight sub column selecting lines in accordance with a signal from the two main column selecting lines and the two sub decoder column selecting lines. The area of the sense amplifier zone can be reduced compared to that of a conventional DRAM in which all signal lines for column selection were provided at a sense amplifier zone.

Disclosed is a method of fabricating a fine pattern by using selective surface reaction such as silylation reaction. A resist for dry development is applied on a semiconductor wafer having an alignment mark formed at a predetermined reference position and comprising a stepped portion. By selectively irradiating the resist by ultraviolet light or electron beams in accordance with a predetermined pattern with reference to the position of the alignment mark, the pattern is transferred onto the resist. A silylated layer of high etching-resistant is selectively formed in a surface of the resist by causing silylation reaction at least in a region of the alignment mark and either a region irradiated by energy beams or a non-irradiated region. This is induced by irradiation of the electron beams or the ultra-violet light, and resulted from the resist heated to a predetermined temperature. Thereafter, before developing the pattern transferred onto the resist, by scanning the resist in a region including at least the alignment mark with the electron beams, the registration of the pattern with the semiconductor wafer is checked. The check of the registration is performed by detecting electrons reflected from the alignment mark and an Auger electrons emitted from the silicon atoms in the silylated layer. The resist can be removed without damaging the underlying substrate even if out-of-registration is detected.

Provided is a power system capable of supplying power steadily to the outside even at a low temperature. A power supply unit disposed in the power system is configured to calculate an amount of power needed to heat a fuel cell to a temperature threshold when the temperature thereof measured by an FC sensor is below the temperature threshold, set an SOC lower limit by adding the calculated amount of power to a discharge threshold of a secondary battery, and control the power supply to a first power supply portion in the range of the SOC lower limit.

A vehicle suitable in consideration of each of an electric power supply amount to a motor and a mounting space of a fuel cell or the like is provided. The outputs of a fuel cell and a battery are raised in voltage by a voltage raising device, and electric power of these raised voltages is supplied to a motor. A total output voltage of the fuel cell and the battery, and their total volume can be correspondingly reduced. The total volume of a group is reduced including the fuel cell, the battery and the voltage raising device, and a mounting space of the group in the vehicle. A space of a frame on an upper side of a floor panel and a lower side of a seat in a vehicle interior space can be utilized effectively as the mounting space of the group, without enlarging the space of the frame.
