  • Publication number: 20060207969
    Abstract: In a substrate treating unit, a removal liquid supplying mechanism supplies a removal liquid to the surface of a substrate. In order to retain the removal liquid on the surface of the substrate for a fixed time, a spin chuck is operated to spin the substrate at such a low speed as to retain the removal liquid on the substrate, or spins the substrate intermittently, or temporarily stops spinning of the substrate. Thus, treatment with the removal liquid progresses without a further supply of the removal liquid, thereby restraining consumption of the removal liquid.

  • Publication number: 20060129585
    Abstract: A server system has, in addition to extensibility of scale-out type of a braid server system, extensibility of scaleup type by making SMP coupling among nodes. Each node has a unit for SMP coupling to other nodes and a module management unit of each node responds to system configuration information to switch between mode in which the node operates singularly as a braid server and mode in which the node operates as a constituent module of an SMP server. Links among individual nodes are laid through equidistant wiring lines on a back plane and besides a loop wiring line having length equal to that of the inter-node link on back plane is also laid in each node, thereby setting up synchronization among nodes. Each node has a reference clock distribution unit mounted on back plane and adapted to distribute reference clocks to individual nodes and by switching reference clocks by a clock distributor inside each node, synchronization of reference clocks for SMP coupled nodes can be established.
