  • Patent number: 9013236
    Abstract: An operational transconductance amplifier for connection with multiple input voltage sources includes a resistance simulation unit, two current cancellation units, a first differential output unit, two current division units, and a second differential output unit. The resistance simulation unit is to simulate resistance. The two current cancellation units are to receive and convert the voltage of the input voltage sources into two first currents. The two first currents flow to two first output ends of the first differential output unit, respectively. The two current division units are to receive and convert the voltage of the input voltage sources into two second currents. The two second currents flow to two second output ends of the two second differential output units, respectively, and include the same potential as the two first currents.

  • Patent number: 8940608
    Abstract: Methods for fabricating integrated circuits are provided. In an embodiment, a method for fabricating an integrated circuit includes providing a semiconductor substrate including a first region of a first doping type, a second region of the first doping type spaced from the first region, a drift region of the first doping type positioned between the first region and the second region, and regions of the opposite doping type. A mask covering both the drift region and the regions of the opposite doping type is formed. Then, a source/drain ion implantation is performed into the first region and the second region. The mask prevents the drift region and the regions of the opposite doping type from receiving the source/drain ion implantation.

  • Patent number: 7749872
    Abstract: Single-crystalline growth is realized using a liquid-phase crystallization approach involving the inhibition of defects typically associated with liquid-phase crystalline growth of lattice mismatched materials. According to one example embodiment, a semiconductor device structure includes a substantially single-crystal region. A liquid-phase material, such as Ge or a semiconductor compound, is crystallized to form the single-crystal region using an approach involving defect inhibition for the promotion of single-crystalline growth. In some instances, this defect inhibition involves the reduction and/or elimination of defects using a relatively small physical opening via which a crystalline growth front propagates. In other instances, this defect inhibition involves causing a change in crystallization front direction relative to a crystallization seed location.

  • Publication number: 20030152300
    Abstract: A pouch has two sheet walls bonded to each other at peripheral edges thereof. A storage chamber is formed in between the sheet walls. The storage chamber has a main chamber and a sub-chamber. The sub-chamber connects to the main chamber and has a smaller size than the main chamber. A bonding potion is defined at an area on the pouch beside the sub-chamber. The sheet walls are fastening to each other at the bonding potion. A guiding line disposes at the bonding potion extending from the end thereof to the sub-chamber. The guiding line divides the bonding potion into a first segment and a second segment. A gap is disposed at the edge of the pouch at the distal end of the guiding line, whereby user can exert the first and the second segments of the bonding potion to tear them apart along the guiding line.
