  • Patent number: 6600679
    Abstract: A level shifter comprises a latch circuit, a first capacitor and a second capacitor. The latch circuit has a first node and a second node set to a first voltage or a second voltage. The second node is set to the second voltage when the first node is set to the first voltage and the second node is set to the first voltage when the first node is set to the second voltage. A first terminal side of the first capacitor is connected to the first node. A first signal is supplied to a second terminal side of the first capacitor. A third terminal side of the second capacitor is connected to the second node. When the first signal is supplied to the second terminal side of the first capacitor, an inverted replica of the first signal is supplied to a fourth terminal side of the second capacitor.

  • Patent number: 6586982
    Abstract: A combination circuit is switched between an active state where power is supplied thereto in response to a control signal and an inactive state where power thereto is interrupted. A flip-flop circuit connected to an input terminal of the combination circuit stores an output signal of the combination circuit in response to a clock signal. The combination circuit is set to an operative state by the control signal immediately before the flip-flop circuit operates in response to the clock signal.

  • Patent number: 6567305
    Abstract: There is provided a semiconductor memory device, which realizes rewriting of data in the memory cell by applying a potential difference between the gate and the source, or applying a potential difference between the gate and the drain, which is larger than the power supply voltage. This semiconductor memory device is provided with a source line potential control circuit configured to control the source line potential. The source line potential control circuit sets the source line potential at the time of the mode for programming “1” data in a plurality of blocks in one package to a level lower than at the normal data programming mode.

  • Patent number: 6544380
    Abstract: An apparatus for treating a substrate which includes a chamber and an opening formed in the chamber allowing the substrate to be conveyed into the chamber or taken out thereof. The chamber, also, includes a detachable baffle plate that fits around an electrode. For treatment to commence, the substrate is placed on the electrode and the chamber is exhausted of or supplied with gases. The electrode is then vertically lifted together with the baffle plate and the baffle plate is moved either to a position that is higher in level than an upper end of the opening of the chamber or to a position that is lower in level than a lower end of the opening of the chamber. This allows the baffle plate to shield a region near the opening of the chamber from a treatment region and allows reaction products to be adhered to the baffle plate.

  • Patent number: 6466511
    Abstract: The semiconductor memory includes a memory cell which handles a clock signal, an address fetch and a command circuit. The memory cell is designated by an address signal and stores data. The clock signal is supplied thereto so as to provide timing for an access to the memory cell, and the clock signal has a leading edge and a trailing edge. The address fetch circuit fetches the address signal for designating the memory cell in synchronism with both of the leading edge and trailing edge of the clock signal. The command circuit fetches a command signal for instructing the access to the memory cell in synchronism with both of the leading edge and the trailing edge of the clock signal.

  • Patent number: 6465290
    Abstract: Claimed and disclosed is a method of manufacturing a semiconductor device, the method comprising the steps of forming a dummy gate on a semiconductor substrate, forming a source-drain diffusion region by introducing an impurity into the semiconductor substrate having the dummy gate as a mask, removing the dummy gate to form an opening, and forming a gate electrode within the opening with a gate insulating film formed below the gate electrode. The dummy gate is further formed by coating the semiconductor substrate with a polymer having a higher carbon content than hydrogen content so as to form a polymer film, forming a photoresist pattern on the polymer film, and transferring the pattern shape of the photoresist pattern onto the polymer film.
