  • Patent number: 10727105
    Abstract: Provided are a semiconductor device and a manufacturing method therefor that can prevent the breakage of an element and in which the control of impurity amounts is less susceptible to variations in manufacturing processes. A semiconductor substrate has a front surface and includes hole portions extending from the front surface to an inside of the substrate. N-type regions are formed in the semiconductor substrate. At wall surfaces of the hole portions, p-type regions are formed to configure p-n junction with the n-type regions. Each of the p-type regions includes a low-concentration region and a high-concentration region formed at the wall surface of each hole portion. A width of the high-concentration region along the wall surface of the hole portion becomes smaller from the front surface toward a deeper position.

  • Publication number: 20200097396
    Abstract: An upper system of an NVM device transmits, to the NVM device, a write command that designates a logical address, the write command being associated with an expiration date corresponding to a data expiration date correlated with write target data. The NVM device correlates an expiration date correlated with the write command with a logical address specified from the write command. The NVM device writes pieces of data of which the remaining time which is the time to an expiration date belongs to the same remaining time range to the same physical storage area among the plurality of physical storage areas. The NVM device erases data from a physical storage area when the expiration dates of all pieces of data in the physical storage area have expired.

  • Patent number: 10600896
    Abstract: In an active region, a gate electrode is disposed in a trench. Spaced apart from the gate electrode, an emitter electrode is disposed in the trench. A source diffusion layer and a base diffusion layer are formed in the active region. The base diffusion layer has a base bottom portion inclined in such a manner that a portion of the base bottom portion adjacent to the emitter electrode is positionally deeper than a portion of the base bottom portion adjacent to the gate electrode. A contact portion has a contact bottom portion inclined in such a manner that a portion of the contact bottom portion in contact with the emitter electrode is positionally deeper than a portion of the contact bottom portion in contact with the base diffusion layer.

  • Patent number: 10507739
    Abstract: A ground device includes a control unit, a storage unit, and a ground transmitting and receiving unit. A ground antenna is connected to the ground transmitting and receiving unit. Train information from an on-board device is received by the ground transmitting and receiving unit via the ground antenna, and is then transmitted to the control unit. Meanwhile, information from the control unit is transmitted to the on-board device via the ground transmitting and receiving unit and the on-board antenna. The control unit accumulates the train information on a train in the storage unit, and also transmits, to the on-board device, command information for a device installed in the train.

  • Publication number: 20190329370
    Abstract: A motor controller comprises: a motor driver arranged at a housing attached to a machine support; fan motors and arranged in or outside the housing; and a control unit. The motor driver drives motors. The fan motors blow cooling air for cooling the interior of the housing. The CPU includes a machining mode selection unit allowing selection of at least either a first machining mode of machining a machining target finely or a second machining mode of machining the machining target more roughly than in the first machining mode. If the first machining mode is selected, the machining mode selection unit exerts control to change the rotation numbers of the fan motors and so as to reduce vibration to be transmitted from the housing to the support column.

  • Patent number: 10381435
    Abstract: A deep trench which reaches a predetermined depth from one principal surface is formed in an element region of a semiconductor substrate. A TEOS oxide film and a polycrystalline silicon film are formed so as to fill the deep trench. In formation of a MOSFET and in formation of a protective insulating film on/over a surface of an element region by thermal oxidation, a silicon thermal oxide film grows, the TEOS oxide film contracts and the polycrystalline silicon film expands when oxidized and turning into a silicon oxide film, and thereby an embedded insulator is formed in the deep trench.
