Title: Method and apparatus to form a planarized cu interconnect layer using electroless membrane deposition
Inventor: REDEKER FRED C
IPC: H01L21/288
Filed: 2004-03-23
Abstract: A planarized conductive material is formed over a substrate including narrow (108) and wide (106) features. The conductive material is formed through a succession of deposition processes. A first deposition process forms a first layer (600) of the conductive material that fills the narrow features and at least partially fills the wide features. A second deposition process forms a second layer (700) of the conductive material within recesses in the first layer. Polishing with a flexible material (1200) can reduce a thickness of the first layer above the substrate while delivering a solution to the recesses to form the second layer therein. The flexible material can be a porous membrane attached to a pressurizable reservoir filled with the solution. The flexible material can also be a poromeric material wetted with the solution.

Title: Dynamic service registry for virtual machines
Inventor: KNAUERHASE ROBERT
IPC: H04W4/02
Filed: 2004-02-25
Abstract: A traditional registry, such as a global UDDI server, is not designed to accommodate transitory devices, e.g., devices that may frequently attach and detach from a network, often-times without warning, such as virtual machines offering or desiring services that are periodically instantiated and then suspended or destroyed. To accommodate such transitory devices, a dynamic resource/service registry may be implemented that leverages lower-level protocols or state to determine appropriate registry updates to keep the registry state consistent with currently-active virtual machines. For example, a virtual machine monitor (VMM) may track creation and suspension or deletion of a virtual machine (VM), and resources advertised by the VM, where the VMM appropriately adds or removes registry entries for the VM as the state of the VM changes or provides hooks (e.g. notifications) or other instrumentation based on said state or protocols to enable other associated modules or agents (e.g. management modules or the registry) to take appropriate actions.

Title: Method for producing a coating on the surface of a particle or on a material and corresponding product
Inventor: GRAMPEIX HELEN
IPC: H01L33/50
Filed: 2004-03-26
Abstract: The invention relates to a method for producing at least one coating (3) on at least one section (4) of the surface of a body (2) by the chemical conversion of at least one constituent of the body into at least one constituent of the coating. The method is characterised in that a chemical, non-metallic compound forms the constituent of the body. The method can be described as an " intrinsic" coating method, as the coating process is not carried out by the external application of material to the surface section, but by the material conversion of the constituent of the body. The method permits the production of a body comprising at least one surface section with at least one coating that has been formed by the chemical conversion of at least one constituent of the body into at least one constituent of the coating. The body is characterised in that the constituent of the body is a chemical, non-metallic compound, for example, a chloride silicate, which is used in the form of luminescent particles as a luminescent substance in a luminescent body (7) of a light-emitting diode (LED). The coating protects the luminescent substance against decomposition by hydration or hydrolysis. The luminescent substance is characterised by improved long-term stability in comparison with similar substances in prior art.
