  • Patent number: 9378036
    Abstract: Methods and systems for routing frames are provided. A routing module of a network device stores a destination address for a virtual machine with a virtual bridge identifier associated with a virtual bridge. The virtual bridge identifier is associated with a queue pair that is used by the virtual machine to send and receive information using the virtual bridge. The network device also includes a port connected to a link for sending and receiving the information and the virtual bridge is associated with the port. The routing module is used to determine the destination of a frame whether the frame is sent by an external device or the virtual machine.

  • Publication number: 20160154310
    Abstract: A method and system provide microelectric devices on fields on a substrate. Each field includes at least one microelectric device having a critical device feature and remaining device feature(s) distal from the critical device feature. The method and system include providing a photoresist layer for fabricating the microelectric devices and exposing the photoresist layer using a dark field mask. The dark field mask is for defining a critical mask feature corresponding to the critical device feature and exposing a first portion of the fields. The first portion includes not more than five percent of each field. The method and system further include exposing the photoresist layer using a clear field mask. The clear field mask is for defining remaining mask feature(s) corresponding to the remaining device feature(s). The clear field mask exposes a second portion of the fields that is different from the first portion.

  • Patent number: 8169473
    Abstract: A method and system for exposing a plurality of fields on a substrate. The substrate has a center and an edge. The fields include a plurality of rows. The method and system include determining an exposure sequence for the plurality of fields. Each of the plurality of fields has a distance from the center and a placement in the exposure sequence. The placement of a field in the exposure sequence is based on the distance and excludes placing each of the plurality of fields in a row of the plurality of rows next to an adjacent field in the row in combination with placing each of the plurality of rows next to an adjacent row. The method and system also include exposing the plurality of fields in the exposure sequence in order of the placement.
