  • Patent number: 7723779
    Abstract: An object of the present invention is to provide an integrated semiconductor nonvolatile storage device that can be read at high speed and reprogrammed an increased number of times. In the case of conventional nonvolatile semiconductor storage devices having a split-gate structure, there is a tradeoff between the read current and the maximum allowable number of reprogramming operations. To overcome this problem, an integrated semiconductor nonvolatile storage device of the present invention is configured such that memory cells having different memory gate lengths are integrated on the same chip. This allows the device to be read at high speed and reprogrammed an increased number of times.

  • Patent number: 7719310
    Abstract: A circuit for attaining reduction in AC noise on power supply line caused by IR drop upon use of a decoupling capacitor represented by a cross-coupled decoupling capacitor with enhanced resistance to electrostatic breakdown, required in the case of a process of a high technology. There is also provided a circuit for suppressing the AC noise on power supply line due to resonance. MOS transistors composing the cross-coupled decoupling capacitor with enhanced resistance to electrostatic breakdown are caused to have lower threshold voltages Vth, thereby reducing a resistance between a source and a drain of each of the MOS transistors, resulting in reduction in IR drop. Further, a damping resistance is effective for suppressing the AC noise on power supply line, and the source-to-drain resistance of each of the MOS transistors is utilized as the damping resistance.

  • Patent number: 7721234
    Abstract: There is a need for keeping the amount of data to be saved and a simulation process time almost constant irrespectively of a hierarchical level of a hierarchical circuit to be simulated. This simulation method includes a first process and a second process. The first process saves result data obtained from simulating an interface node between higher-level and lower-level hierarchies in accordance with a result of simulation using hierarchical circuit data hierarchized for multiple hierarchies. The second process uses result data saved by the first process to reproduce internal node data not saved by the first process. Result data for the interface node between hierarchies indirectly determines a value for the internal node. Result data to be saved is data concerning the interface node between hierarchies. The amount of saved data and the time needed for the second process are independent of a hierarchical level or a higher-level or lower-level hierarchy.

  • Patent number: 7713884
    Abstract: A semiconductor wafer is placed in a chamber of a film-deposition apparatus, and gas in the chamber is exhausted from a gas exhaust outlet. Then, with interrupting the exhaust, an inert gas is introduced into the chamber so that the chamber has a pressure of 133 Pa or higher and lower than 101325 Pa, and then a mixed gas of an inert gas and a source gas for depositing a metal oxide film is introduced into the chamber. Then, after exhausting the gas in the chamber, an oxidation gas is introduced into the chamber to react with the molecules of the source gas absorbed on the semiconductor wafer to form a metal oxide film on the semiconductor wafer. By repeating these steps, a metal oxide film having a desired film thickness is deposited on the semiconductor wafer with a film-thickness distribution by an ALD method.

  • Patent number: 7714606
    Abstract: A plurality of MOS transistors each having an SOI structure includes, in mixed form, those brought into body floating and whose body voltages are fixed and variably set. When a high-speed operation is expected in a logic circuit in which operating power is relatively a low voltage and a switching operation is principally performed, body floating may be adopted. Body voltage fixing may be adopted in an analog system circuit that essentially dislikes a kink phenomenon of a current-voltage characteristic. Body bias variable control may be adopted in a logic circuit that requires the speedup of operation in an active state and needs low power consumption in a standby state. Providing in mixed form the transistors which are subjected to the body floating and the body voltage fixing and which are variably controlled in body voltage, makes it easier to adopt an accurate body bias according to a circuit function and a circuit configuration in terms of the speedup of operation and the low power consumption.

  • Patent number: 7715078
    Abstract: It is an object to realize smooth switching between free scanning and high speed scanning in a light scanning apparatus and a light scanning microscope. To attain the object, a light scanning apparatus includes at least three mirror scanners disposed at predetermined positions of a light path for light scanning, and a light path switching unit switching the light path between a light path in which a highest-speed mirror scanner among the mirror scanners is valid and a light path in which the highest-speed mirror scanner is invalid. Therefore, the switching between a free scanning mode and a high speed scanning mode is performed by the driving of the light switching unit and involves no movement of galvanometer scanners. In addition, since the resonant galvanometer scanner is invalid during the free scanning mode, it is possible to make the resonant galvanometer scanner on standby.

  • Patent number: 7709315
    Abstract: An interface between a bottom oxide film and a silicon nitride film in a neighborhood of a bottom part of a select gate is located at a position as high as or higher than that of an interface between a silicon substrate (p-type well) and a gate insulating film (d?0) Further, the gate insulating film and the bottom oxide film are successively and smoothly jointed in the neighborhood of the bottom part of the select gate. By this configuration, localization in a distribution of electrons injected into the silicon nitride film in the writing is mitigated and electrons to be left unerased by hot-hole erasing are reduced. Therefore, not only the increase ratio of the electrons left unerased in the writing can be reduced, but also the problem in which the threshold voltage does not decrease to the predetermined voltage in the deletion can be suppressed.

  • Patent number: 7709937
    Abstract: A semiconductor device which includes: a semiconductor chip with plural pads; a tab connected with the semiconductor chip; bus bars which are located outside of the semiconductor chip and connected with the tab; a sealing body which resin-seals the semiconductor chip; plural leads arranged in a line around the semiconductor chip; plural first wires which connect pads of the semiconductor chip and the leads; and plural second wires which connect specific pads of the semiconductor chip and the bus bars. Since the sealing body has a continuous portion which continues from a side surface of the semiconductor chip to its back surface to a side surface of the tab, the degree of adhesion among the semiconductor chip, the tab and the sealing body is increased. This prevents peeling between the tab and the sealing body during a high-temperature process and thus improves the quality of the semiconductor device (QFN).

  • Patent number: 7706208
    Abstract: If memory cell blocks are laid out in a conventional manner to create a memory chip with a capacity of an odd power of 2 by using memory cells whose aspect ratio is 1:2, the chip will take a 1:1 shape and become difficult to enclose in a package of a 1:2 shape. In addition, such conventional layout of memory cell blocks to form the 1:2 shape causes the area of a peripheral circuit region to be limited by the memory blocks, pads to be arranged collectively in the central section of the chip, and wiring to become dense during the enclosure of the chip in the package. In this invention, therefore, four memory blocks, BANK0, BANK1, BANK2, BANK3, BANK3, are constructed into an L shape and then these memory blocks are properly combined and arranged to construct a chip of nearly a 1:2 shape in terms of aspect ratio.
