  • Patent number: 7413990
    Abstract: A method of fabricating an interconnect structure (e.g., dual damascene interconnect structure, and the like) of an integrated circuit device is disclosed. The interconnect structure is fabricated using a bi-layer mask comprising an imaging film and an organic planarizing film. The bi-layer mask is used to remove lithographic misalignment between a contact hole, a trench, and an underlying conductive line when the interconnect structure is formed. Additionally, a sacrificial layer may be used to protect an inter-metal dielectric (IMD) layer during subsequent planarization of the interconnect structure. The sacrificial layer may be formed of amorphous silicon (Si), titanium nitride (TiN), tungsten (W), and the like. The interconnect structure may be formed of a metal (e.g., copper (Cu), aluminum (Al), tantalum (Ti), tungsten (W), titanium (Ti), and the like) or a conductive compound (e.g., tantalum nitride (TaN), titanium nitride (TiN), tungsten nitride (WN), and the like).

  • Patent number: 7313010
    Abstract: A ferroelectric reference circuit generates a reference voltage proportional to (P+U)/2 and is automatically centered between the bit line voltages corresponding to the P term and the U term across wide temperature and voltage ranges. To avoid fatiguing the reference ferroelectric capacitors generating (P+U)/2, the reference voltage is refreshed once every millisecond. To eliminate the variation of the reference voltage due to the leakage in the ferroelectric capacitors during this period of time, the reference voltage generated from the reference ferroelectric capacitors is digitized when it is refreshed. The digital value is fixed and converted to an analog value which is then fed into sense amplifiers for resolving the data states. The reference voltage is automatically at the center of the switching (P) and non-switching (U) signals and therefore the signal margin is maximized.

  • Publication number: 20070264249
    Abstract: The present invention comprises a method to diminish and/or eliminate atherosclerotic plaques, in mammals, through direct and indirect treatment of these plaques, in situ, using suitable substances which are capable of lipid removal, primarily through hydrolysis, either by a catalytic or stoichiometric process, wherein the substance targets receptors in and/or on the cell which lead to uptake into the lysosome. Such substances used to diminish and/or eliminate atherosclerotic plaques are generally comprised of lipid hydrolyzing proteins and/or polypeptides.

  • Publication number: 20070253166
    Abstract: A lamp base assembly with electronic ballast for energy-saving lamp includes a housing (22), a lamp cap (21) and an electronic ballast (24) with transistors (23) provided within the housing. A transistor heat-diffusing element surrounding each transistor is provided within the lamp base, for enhancing the heat transfer from the transistors to the housing or the lamp cap, so that the heat generated from the transistors could be transferred out of the lamp base assembly. Thus, the heat-diffusing ability of the transistors is improved, and the working temperature of the transistors could be kept within a safe scope, so that the lifetime of the energy-saving lamp is guaranteed.

  • Patent number: 7271744
    Abstract: An encoder utilizes a coding method for use with ferroelectric or other nonvolatile counters which are subject to imprint ensures that all of the bits in the code are frequently switched and not left in a fixed data state. The general coding equation for this method is such that: for an even integer n, it is represented by the conventional binary code of n/2; for an odd integer n, it is represented by the conventional binary code of the one's compliment of (n?1)/2. With this method, every bit switches to its compliment when counting from an even number to an odd number so that imprint is substantially reduced.

  • Patent number: 7233194
    Abstract: This invention is a new CMOS voltage booster (20) having an output which can be used in memories to boost the word line voltage above VDD or other voltage boosting applications. The CMOS booster includes a NMOS FET (MN1) to charge a boosting capacitor (C1) to VDD at the end of each memory access and includes a PMOS FET (MP1, MP2) to keep the voltage at the output at VDD during standby. By using this combination, the word line rise time, the size of the booster, and the power consumption during access are significantly reduced. The gate of the NMOS FET (MN1) is boosted above VDD+Vthn by a small capacitor (C2) to charge the word line boosting capacitor to VDD at the end of each memory access. The small capacitor (C2) is pre-charged to VDD by a NMOSFET (MN2) whose gate is connected to the word line boosting capacitor. The gate of each PMOS FET (MP1, MP2) is shorted to its source to turn if off during boostenig. Transistor (MP3) facilitates boosting the NMOS FET (MN1) above VDD.

  • Patent number: 7142627
    Abstract: A counting scheme for a non-volatile counter includes automatic point-of-reference generation implemented in a state machine. Two state variables are used to store the rotation history of the magnet. One variable stores the previous position of the magnet and the other stores the net angle traveled by the magnet from the reference point. The first pulse location after the counter is reset is automatically selected as the reference point until the next counter reset. When the nonvolatile counter counts up or down, i.e. when the magnet travels 360° in either direction, the second state variable is set to zero and the first state variable is set to the reference point, indicating the start of a new revolution.
