This invention relates to a method of epitaxial growth effectively preventing auto-doping effect. This method starts with the removal of impurities from the semiconductor substrate having heavily-doped buried layer region and from the inner wall of reaction chamber to be used. Then the semiconductor substrate is loaded in the cleaned reaction chamber to be pre-baked under vacuum conditions so as to remove moisture and oxide from the surface of said semiconductor substrate before the extraction of the dopant atoms desorbed from the surface of the semiconductor substrate. Next, under high temperature and low gas flow conditions, a first intrinsic epitaxial layer is formed on the surface of said semiconductor substrate where the dopant atoms have been extracted out. Following this, under low temperature and high gas flow conditions, a second epitaxial layer of required thickness is formed on the structural surface of the grown intrinsic epitaxial layer. Last, silicon wafer is unloaded after cooling. This method can prevent auto-doping effect during the epitaxial growth on semiconductor substrate and thus ensure the performance and enhance the reliability of the devices in peripheral circuit region.

A system and method for allocating resources in a cloud environment includes determining permitted usage of virtual machines and partitioning resources between network servers in accordance with a virtual hyperviser generated in accordance with an abstraction layer configured as an interface between a solution manager and an interface to a cloud network. Resource usage limits are determined for each virtual machine associated with the virtual hyperviser, and the servers are analyzed through the virtual hypervisers to determine if the virtual machines need to be migrated. If reallocation is needed, virtual machine migration requests are issued to migrate virtual machines into a new configuration at the virtual hypervisor abstraction level. The servers are reanalyzed to determine if migration of the new configuration is needed. Shares are computed to enforce balance requirements, and virtual machine shares and limits are adjusted for resources according to the computed shares.

Due to a centrifugal force in a vehicle width direction due to turning of an automobile, oil in an electric motor housing chamber housing an electric motor and oil in a transmission housing chamber housing a reduction gear and a differential gear flows to-and-fro via oil communication passages that penetrate a partitioning wall. An opening on the transmission housing chamber side of the oil communication passages is spaced from the partitioning wall. Hence, when oil moves from the transmission housing chamber side to the electric motor housing chamber side, it is possible to prevent the oil quantity on the electric motor housing chamber side from increasing excessively and suppress an increase in resistance to oil stirring by a rotor of the electric motor while retaining a constant oil amount on the transmission housing chamber side to ensure lubricating performance for the reduction gear and the differential gear.

The ensuring of predictable and quantifiable networking performance. Embodiments of the invention combine a congestion free network core with a hypervisor based (i.e., edge-based) throttling design to help insure quantitative and invariable subscription bandwidth rates. A lightweight shim layer in a hypervisor can adaptively throttle the rate of VM-to-VM traffic flow. A receiving hypervisor can detect congestion and communicate back to sending hypervisors that rates are to be regulated. In response, sending hypervisors can reduce transmission rate to mitigate congestion at the receiving hypervisor. In some embodiments, the principles are extended to any message processors communicating over a congestion free network.
