  • Patent number: 7214632
    Abstract: A phase-change memory cell may be formed by selectively depositing the lower electrode in the phase-change memory pore. Thereafter, an adhesion-promoting material may be selectively deposited on the selectively deposited lower electrode and the upper surface surrounding the pore. Through the use of selective deposition techniques, the adhesion-promoting material can be positioned where needed and the lower electrode may be defined in a fashion that may reduce shunting current, reduce device current requirements, and increase dynamic range in some embodiments.

  • Publication number: 20070056371
    Abstract: A portable electronic device disposed in a car is provided. The portable electronic device includes a power switch, a vibration sensor and a controller. The power switch is used for providing a first power at a first state and providing a second power at a second state. The vibration sensor is used for outputting a vibration signal after sensing the vibration of the car. The vibration sensor is used for terminating the output of vibration signal when not sensing the vibration of the car. The controller is electrically connected to the vibration sensor and the power switch. When the controller receives the vibration signal, the controller controls the power switch to be at the first state and provide the first power. When the controller does not receive the vibration signal, the controller controls the power switch to be at the second state and provide the second power.

  • Patent number: 7179715
    Abstract: The formation of gate spacers on the sides of a gate structure on a semiconductor substrate is provided. In one embodiment, a gate structure is formed on a gate insulator layer of the semiconductor substrate. A liner layer is formed over the exposed surfaces of the substrate, the gate insulator layer, and the gate structure. A layer of gate spacer material is formed over the liner layer. Thereafter, gate spacers are formed from the layer of gate spacer material. A protection layer is formed over portions of the liner layer, gate structure, and the gate spacers. The protection layer is etched back. A first wet etch procedure is performed to remove exposed portions of the liner layer. The protection layer is removed and a second wet etch procedure is performed to remove substantially a top portion and a bottom portion of the liner layer.

  • Publication number: 20070025086
    Abstract: An electronic device with sliding type heatsink including a printed circuit board, a heat dissipation module and at least a guide post is provided. Wherein, a heat-generating element is disposed on the printed circuit board, and the heat dissipation module is disposed on the heat-generating element. The heat dissipation module includes at least an elastic element which has an assembly hole. The assembly hole has a guide part and a first fixing part. Besides, the guide post protrudes from the printed circuit board and is located in the assembly hole. A side of the guide post has a groove. When the heat dissipation module moves a suited distance, the groove slides into the first fixing part from the guide part that makes the guide post fix with the first fixing part. Thus, the heat dissipation module can tightly fix on the heat-generating element.
