Distributed load balancing systems
Some embodiments provide a novel method for load balancing data messages that are sent by a source compute node (SCN) to one or more different groups of destination compute nodes (DCNs). In some embodiments, the method deploys a load balancer in the source compute node's egress datapath. This load balancer receives each data message sent from the source compute node, and determines whether the data message is addressed to one of the DCN groups for which the load balancer spreads the data traffic to balance the load across (e.g., data traffic directed to) the DCNs in the group. When the received data message is not addressed to one of the load balanced DCN groups, the load balancer forwards the received data message to its addressed destination. On the other hand, when the received data message is addressed to one of load balancer's DCN groups, the load balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message to the identified DCN. To direct the data message to the identified DCN, the load balancer in some embodiments changes the destination address (e.g., the destination IP address, destination port, destination MAC address, etc.) in the data message from the address of the identified DCN group to the address (e.g., the destination IP address) of the identified DCN. |

Facet-free strained silicon transistor
The presence of a facet or a void in an epitaxially grown crystal indicates that crystal growth has been interrupted by defects or by certain material boundaries. Faceting can be suppressed during epitaxial growth of silicon compounds that form source and drain regions of strained silicon transistors. It has been observed that faceting can occur when epitaxial layers of certain silicon compounds are grown adjacent to an oxide boundary, but faceting does not occur when the epitaxial layer is grown adjacent to a silicon boundary or adjacent to a nitride boundary. Because epitaxial growth of silicon compounds is often necessary in the vicinity of isolation trenches that are filled with oxide, techniques for suppression of faceting in these areas are of particular interest. One such technique, presented herein, is to line the isolation trenches with SiN to provide a barrier between the oxide and the region in which epitaxial growth is intended. |

The groove member has: a groove-forming portion having a groove opening downward formed therein, a surrounding wall portion, which is connected to the groove-forming portion, and is arranged around the groove-forming portion; and a locked portion, which is connected to the surrounding wall portion, is elastically deformable, and is locked by way of the locking portion of the bottom plate by being elastically deformed. The groove member is supported and fixed by way of the lower wall and the bottom plate. |

Substrate peripheral portion measuring device, and substrate peripheral portion polishing apparatus
A projecting/receiving unit (52) projects a laser light to a peripheral portion (30) and receives the reflected light while a liquid is being fed to a substrate (14) and is flowing on the peripheral portion (30). A signal processing controller (54) processes the electric signal of the reflected light to decide the state of the peripheral portion (30). The state of the peripheral portion being polished is monitored. Moreover, the polish end point is detected. A transmission wave other than the laser light may also be used. The peripheral portion (30) may also be enclosed by a passage forming member thereby to form a passage properly. The peripheral portion can be properly measured even in the situation where the liquid is flowing on the substrate peripheral portion. |

Semiconductor manufacturing apparatus and method of manufacturing semiconductor device
In one embodiment, a semiconductor manufacturing apparatus includes a support module configured to support a wafer having first and second faces. The apparatus further includes a chamber configured to contain the support module. The apparatus further includes a microwave generator configured to generate a microwave. The apparatus further includes a waveguide configured to emit the microwave into the chamber to irradiate the first or second face of the wafer with the microwave, the waveguide being provided to the chamber such that an incidence direction of the microwave emitted from the waveguide onto the first or second face is non-vertical to the first or second face. |
