  • Patent number: 7295551
    Abstract: Methods and apparatus for registering a mobile device such as a mobile node or mobile router with a Home Agent in an asymmetric link environment. A Foreign Agent associates each of one or more interfaces of the Foreign Agent with a different care-of address. An agent advertisement including the care-of address for the one or more interfaces of the Foreign Agent is then sent via one or more uplinks. A registration request is received via a downlink router. The registration request identifies a care-of address associated with one of the one or more interfaces of the Foreign Agent. One of the interfaces identified by the care-of address is ascertained, thereby identifying the interface to which the mobile device has roamed. The registration request is forwarded to the Home Agent. A registration reply is received from the Home Agent. The registration reply is then forwarded to the mobile device via the ascertained interface.

  • Patent number: 7200824
    Abstract: Methods and apparatus are provided for harnessing the effects of process variations in a semiconductor device. In one example, implementing an electronic design based on collected performance parameters is provided. In general, a core is segmented into multiple core regions. A performance parameter can be collected from each of the core regions. The performance parameter can be collected with a performance measuring mechanism associated with the core region. The performance parameter can be correlated to the performance requirements of an electronic device portion, and the electronic design portion can be implemented in a core region that has a performance parameter matched to the needs of the electronic design portion. In this way, process variation effects are harnessed by optimizing the implementation of the electronic design in regions of the semiconductor device best suited the needs of each electronic design portion. Therefore, performance/power optimization of the semiconductor device can be realized.

  • Patent number: 7186648
    Abstract: Methods for forming a diffusion barrier on low aspect features of an integrated circuit include at least three operations. The first operation deposits a barrier material and simultaneously etches a portion of an underlying metal at the bottoms of recessed features of the integrated circuit. The second operation deposits barrier material to provide some minimal coverage over the bottoms of the recessed features. The third operation deposits a metal conductive layer. Controlled etching is used to selectively remove barrier material from the bottom of the recessed features, either completely or partially, thus reducing the resistance of subsequently formed metal interconnects.

  • Patent number: 7176673
    Abstract: A direct current detection circuit has a zero-phase current transformer with source lines inserted therethrough for detecting current differences among them and generates a comparison voltage value based on a divided voltage value obtained between the zero-phase current transformer and a voltage divider resistor according to a change in the self-impedance of the zero-phase current transformer. An offset current is passed through the zero-phase current transformer to make it possible to detect on the basis of the comparison voltage value a direct current value in a range which is otherwise difficult to detect accurately on the basis of the comparison voltage value because of influence of hysteresis characteristic of the zero-phase current transformer. A control circuit detects a present direct current value based on the comparison voltage value and the value of the offset current.

  • Patent number: 7176144
    Abstract: Methods of preparing a low-k dielectric material on a substrate are provided. The methods involve using plasma techniques to remove porogen from a precursor layer comprising porogen and a dielectric matrix and to protect the dielectric matrix with a silanol capping agent, resulting in a low-k dielectric matrix. Porogen removal and silanol capping can occur concurrently or sequentially. If performed sequentially, silanol capping is performed without first exposing the dielectric matrix to moisture or ambient conditions.
