    摘要: A small and highly sensitive capacitance type pressure sensor is obtained by filling an alkali halide material such as KBr into a through-hole, forming a conductive thin film on the surface, and dissolving and removing the alkali halide material. An insulating plate disposed with a through-hole in the thickness direction is filled with a molten alkali halide material such as KBr. After forming a conductive thin film on the surface of the alkali halide material filled into the through-hole and the vicinity thereof, the alkali halide material is dissolved by water and removed. In this way, a diaphragm is made of the through-hole and the conductive thin film. A curve of the diaphragm caused by a pressure difference between the both faces of the conductive thin film is detected as a capacitance change between the conductive thin film and the electrode layer.

    摘要: A memory system in embodiments includes a nonvolatile semiconductor memory that stores user data, a forward lookup address translation table and a reverse lookup address translation table, and a controller. The controller is configured to determine that the user data stored in the nonvolatile semiconductor memory is valid or invalid based on these two tables. The controller may perform data organizing of selecting data determined valid and rewriting the data in a new block. The controller may perform write processing and rewriting processing to the new block alternately at a predetermined ratio. The controller may determine whether a predetermined condition is satisfied on a basis of addresses included in write requests and write data in the MLC mode when the condition is satisfied and write data in the SLC mode when the condition is not satisfied.

    摘要: A semiconductor device for control applied to a constant-voltage power supply device includes a digital-analog converter circuit which outputs a reference voltage corresponding to a value of a first register with taking an output voltage of a reference voltage source as a criterial reference voltage, and generates a control signal for driving a power semiconductor device based on an output voltage of an error amplifier which differentially amplifies a feedback voltage obtained by resistive-dividing on an output voltage of the constant-voltage power supply device and the reference voltage. An analog-digital converter circuit which converts the feedback voltage to a digital value with taking the output voltage of the constant-voltage power supply device as a reference voltage is provided, and based on the output, a value of a first register is corrected so as to offset an effect of an error in voltage dividing ratio of a voltage dividing resistor circuit.

    摘要: A manufacturing method of a thin film transistor includes forming a pair of source/drain electrodes on a substrate, such that the source/drain electrodes define a gap therebetween; forming low resistance conductive thin films, which define a gap therebetween, on the source/drain electrodes; and forming an oxide semiconductor thin film layer on upper surface of the low resistance conductive thin films and in the gap defined between the low resistance conductive thin films so that the oxide semiconductor thin film layer functions as a channel. The low resistance conductive thin films and the oxide semiconductor thin film layer are etched so that side surfaces of the resistance conductive thin films and corresponding side surfaces of the oxide semiconductor thin film layer coincide with each other in a channel width direction of the channel. A gate electrode is mounted over the oxide semiconductor thin film layer.
