  • Patent number: 6380998
    Abstract: A LCD device has a LCD panel and a drive TCP for driving the LCD panel. Back light is guided to the rear surface of the LCD panel by a light-conductive sheet. The leakage back light passed the rear surface of the light-conductive sheet is reflected by a reflecting plate having a conductive film at the rear surface of the reflecting plate. The conductive film is connected to a ground pattern of the printed circuit board which transfers signals to the drive TCP. The reflecting plate has both functions for reflecting back light and shielding the LCD panel against the noise generated by the printed circuit board.

  • Patent number: 6377127
    Abstract: In a phase locked loop circuit, a phase difference signal (an up signal and a down signal) is supplied from a phase comparator to a serial-to-parallel converting circuit, and an output of the serial-to-parallel converting circuit is supplied to an up-down counter having a count value is counted up or down in accordance with the phase difference detected by the phase comparator. A voltage controlled oscillator generates an oscillation signal having the frequency controlled in accordance with the count value of the up-down counter. Thus, since the phase difference signal is serial-to-parallel converted, the rate of the phase difference signal is lowered, so that the operation speed of the up-down counter can be relaxed. Therefore, the operation speed of the phase locked loop circuit can be elevated with elevating the operation speed of the up-down counter.

  • Patent number: 6372591
    Abstract: A fabrication method of a semiconductor device is provided, which makes it possible to form shallow extensions (e.g., 0.1 &mgr;m or less in depth) of source/drain regions of a MOSFET with a double drain structure. In the step (a), a gate electrode is formed over a main surface of a single-crystal Si substrate of a first conductivity type through a gate insulating film. In the step (b), a dopant of a second conductivity type is ion-implanted into the substrate at an acceleration energy of 1 keV or lower under a condition that the amount of point defects induced in this step (b) is minimized or decreased, thereby forming first and second doped regions of the second conductivity type. In the step (c), a pair of sidewalls spacers are formed.

  • Patent number: 6372114
    Abstract: A method of forming a multi-layer structure over an insulating layer comprises the steps of: selectively depositing a barrier layer on a predetermined region of an insulating layer by use of a first deposition mask; selectively depositing a metal seed layer made of a metal which is different in substance from the barrier layer by use of a second deposition mask, so that the metal seed layer extends not only on an entire surface of the barrier layer but also a peripheral region positioned outside the predetermined region of the insulating layer; and forming a metal plating layer made of the metal of the metal seed layer, so that the metal plating layer is adhered on the metal seed layer whereby the metal plating layer is separated from the barrier layer and also from the insulating layer.

  • Patent number: 6366063
    Abstract: When a first switch is closed, a power-supply voltage V is applied to a serial resonance circuit that is made up of a coil and a capacitive load. When the voltage Vc of the capacitive load exceeds the power-supply voltage V, a diode conducts a current, and thereby the voltage Vc of the capacitive load is clamped at the power-supply voltage V, and resonance stops. As a result, a flywheel current flows through a closed loop that is made up of a coil, a first diode, and a first switch in a closed state, in this order. When the first switch is opened, the flywheel current has the loop shut off, and, therefore, the voltage of the serial resonance circuit falls rapidly in order to sustain or maintain the current, and falls below the earth potential so as to allow a second diode to conduct the current.

  • Patent number: 6361854
    Abstract: A process for manufacturing a metallized substrate using the island coating method, includes depositing a coating layer containing a radiation curable non-volatile film former. The coated part is then vacuum metallized to form the metal islands of the present invention. A layer of clear resinous protective dielectric topcoat containing a radiation curable non-volatile film former is then deposited to completely cover the layer of metal islands while maintaining the aesthetic properties of the metallizing island coating system at a reduced cost and with minimal variability among parts.

  • Patent number: 6359234
    Abstract: A package substrate in which a semiconductor chip is placed is disclosed. A through hole land (opposed conductor) connected to a signal wiring is opposite to a fixed electrical potential conductor through an insulator layer. The through hole land is disposed in a wiring layer on the outermost side of wiring layers of the package substrate. The through hole land connected to the signal wiring for input/output of signals at a higher frequency has a larger size. The through hole lands connected to the signal wiring for input/output of signals at a certain frequency and the through hole lands connected to the signal wiring for input/output of signals at a lower frequency than the certain frequency are alternately arranged. The through hole land, the insulator layer and the fixed electrical potential conductor form a capacitor and serve as a stub, thereby reducing impedance of the signal wiring connected thereto.
