  • Publication number: 20080237675
    Abstract: A capacitor includes a substrate (110, 210), a first electrically insulating layer (120, 220) over the substrate, and a fin (130, 231) including a semiconducting material (135) over the first electrically insulating layer. A first electrically conducting layer (140, 810) is located over the first electrically insulating layer and adjacent to the fin. A second electrically insulating layer (150, 910) is located adjacent to the first electrically conducting layer, and a second electrically conducting layer (160, 1010) is located adjacent to the second electrically insulating layer. The first and second electrically conducting layers together with the second electrically insulating layer form a metal-insulator-metal stack that greatly increases the capacitance area of the capacitor. In one embodiment the capacitor is formed using what may be referred to as a removable metal gate (RMG) approach.

  • Patent number: 7409631
    Abstract: An error-detection flip-flop is disclosed for identifying timing errors in digital circuits. The error-detection flip-flop is a master-slave flip-flop including logic to determine whether an input signal is received during a predetermined clock period, signifying a timing error. The error-detection flip-flop produces a variable-length error pulse, which may be combined with other error pulses and converted to a stable signal for sampling by error-correction circuitry. The error-detection flip-flop does not increase the clocking power of the digital circuit and consumes little additional circuit area.
