  • Publication number: 20100061309
    Abstract: A mobile node includes a processor, a network interface, and a storage device having computer program code for execution by the processor. The computer program code includes a network layer for transmitting and receiving packets and an intermediate driver that transmits packets to the network layer and receives packets from the network layer using a virtual interne protocol (IP) address to identify the mobile node. The intermediate driver transmits packets to the network interface and receives packets from the network interface using a routable actual IP address to identify the mobile node. The intermediate driver permits the actual IP address to change when the mobile node moves from a first subnet to a second subnet without a corresponding change in the virtual IP address. A corresponding NAT associates the virtual IP address with a second actual IP address when the NAT is notified that the mobile node is in the second subnet.

  • Publication number: 20090170277
    Abstract: A method for semiconductor processing is provided, wherein a removal of one or more layers is aided by structurally weakening the one or more layers via ion implantation. A semiconductor substrate is provided having one or more primary layers formed thereon, and a secondary layer is formed over the one or more primary layers. One or more ion species are implanted into the secondary layer, therein structurally weakening the secondary layer, and a patterned photoresist layer is formed over the secondary layer. Respective portions of the secondary layer and the one or more primary layers that are not covered by the patterned photoresist layer are removed, and the patterned photoresist layer is further removed. At least another portion of the secondary layer is removed, wherein the structural weakening of the secondary layer increases a removal rate of the at least another portion of the secondary layer.

  • Publication number: 20080217703
    Abstract: A method for manufacturing an isolation structure is disclosed that protects the isolation structure during etching of a dichlorosilane (DCS) nitride layer. The method involves the formation of a bis-(t-butylamino)silane-based nitride liner layer within the isolation trench, which exhibits a five-fold greater resistance to nitride etching solutions as compared with DCS nitride, thereby allowing protection against damage from unintended over-etching. The bis-(t-butylamino)silane-based nitride layer also exerts a greater tensile strain on moat regions that results in heightened carrier mobility of active regions, thereby increasing the performance of NMOS transistors embedded therein.
