  • Patent number: 10868764
    Abstract: A route calculation control device includes a calculator configured, among a plurality of nodes constituting a physical network having a plurality of sections to which respective policies different from each other are applied when allocating resources, based on a policy corresponding to a section including a start point node specified in a use request of the resources of the physical network, to calculate a route from the start point node to an end point node specified in the use request; and a controller configured to replace the start point node, among nodes constituting the route calculated by the calculator, with a first node included in a section different from the section including the start point node, so as to cause the calculator to calculate a route to the end point node. This enables to allocate resources to a network that includes multiple sections to which different policies are applied.

  • Patent number: 10660069
    Abstract: A resource allocation device is provided that, responsive to a use request for resources of a network, the use request having a pair of nodes as terminal points designated among a plurality of nodes constituting the network, searches for one or more candidate paths between the terminal points, with which amounts of the resources related to the use request can be allocated, in a state where the resources that have been allocated to one or more other use requests are set aside from the network. The device calculates, for each of the one or more searched-for-candidate paths, in a state where the resources are allocated to the candidate path, a maximum number of paths that can be allocated between the terminal points of a virtual path related to the service, and selects the candidate path with which a sum total of the maximum numbers of paths becomes greatest.

  • Publication number: 20020109135
    Abstract: The MOS field-effect transistor aims to enhance the electron mobility and the hole mobility in the channel portion by employing the strained-Si/SiGe (or Si/SiGeC) structure. Crystallinity of such a heterostructure is maintained in a preferable state, shortening of the effective channel length is prevented, diffusion of Ge is prevented and the resistance of the source layer and the drain layer is reduced. The channel region has a layered structure formed by stacking the Si layer and, the SiGe or SiGeC layer in order from the surface. The source layer and the drain layer formed of SiGe or SiGeC including high concentration impurity atoms providing a desired conduction type, are in contact with both end surfaces of the channel region. The surfaces of the source layer and the drain layer have a shape rising upwardly from the bottom portion of the gate electrode.

  • Publication number: 20020008289
    Abstract: A semiconductor device is disclosed which allows for ease of fabrication of CMOS LSI chips and is adapted to increase the mobility of electrons and holes. The semiconductor device comprises a substrate, an insulating layer formed over the substrate, and a stacked Si/SiGe/Si region comprising a first layer of Si, a layer of SiGe, and a second layer of Si which are sequentially formed in this order on the insulating layer. The topmost second layer of Si and the layer of SiGe are strained due to the difference in lattice constant between each layer in the stacked Si/SiGe/Si region. An n-MOSFET and a p-MOSFET are formed in the stacked region. The n-MOSFET has a surface channel consisting of the second Si layer, whereas the p-MOSFET has a double channel of a buried channel consisting of the SiGe layer and a surface channel consisting of the second Si layer.

  • Patent number: 5989981
    Abstract: A method of manufacturing an SOI substrate uses an SOI substrate having a first single-crystal silicon layer, an insulating layer formed on the first single-crystal silicon layer, and a second single-crystal silicon layer formed on the insulating layer. The surface of the second single-crystal silicon layer is thermally oxidized. The second single-crystal silicon layer is controlled to have a predetermined thickness by removing the thermally oxidized surface. This step controlling the second single-crystal silicon layer to have a predetermined thickness includes the step of eliminating, by annealing, a stacking fault formed by the thermal oxidation.
