International Classification:

C23C 1600

US Classification:

118723E, 118715

Abstract:

An apparatus and method for preventing particulate matter and residue build-up within a vacuum exhaust line of a semiconductor-processing device. The apparatus includes a vessel chamber having an inlet, an outlet and a fluid conduit between the two that fluidly couples the outlet with the inlet. The fluid conduit includes first and second collection sections. The first collection section includes a first plurality of electrodes aligned parallel to a first plane and the second collection section includes a second plurality of electrodes aligned parallel to a second plane that is substantially perpendicular to the first plane. The electrodes are connected to a voltage differential to form an electrostatic particle collector that traps electrically charged particles and particulate matter flowing through the fluid conduit. Particles are collected on the electrodes within the fluid conduit during substrate processing operations such as CVD deposition steps. Then, during a chamber clean operation, unreacted etchant gases used to clean the substrate processing chamber are exhausted through the foreline and into the apparatus of the present invention where they react with the collected particles and powder to convert the solid material into gaseous matter that can be pumped through the foreline without damaging the vacuum pump or other processing equipment.

Abstract:

The present invention recognizes that the build-up of residue in a metal alloy injection valve used to inject a liquid phosphorous precursor compound is due to the nickel in the alloy affecting the liquid phosphorous precursor compound. The invention thus provides components manufactured of an alloy having a low nickel content, preferably less than 5% nickel, and more preferably less than 1%. In an additional aspect of the invention, the alloy is provided with a higher chromium content, preferably at least 15% chromium, more preferably 16-27%.

Abstract:

An architecture for controlling a multiprocessing system to provide at least one network service to subscriber data packets transmitted in the system using a plurality of compute elements, comprising a management compute element including service set-up information for at least one service and at least one processing compute element applying said at least one network service to said data packets and communicating service set-up information with the management compute element in order to perform service specific operations on data packets. In a further embodiment, a method of controlling a processing system including a plurality of processors is disclosed. The method comprises the steps of operating at least one of said processors as a control authority providing service provisioning information for a subscriber; and operating a set of processors as a service specific compute element responsive to the control authority, receiving provisioning information from the subscriber and performing service specific instructions on data packets to provide IP content services.

US Classification:

156/345320, 118/72300E

Abstract:

A series of modular apparatuses for processing substrates using a unique combinations of a substrate coating subsystem, a substrate curing subsystem and a PECVD-based capping subsystem. The individual subsystems are capable of being combined with one another for creating unique integrated substrate processing apparatuses that enable combined processing by the coating, curing and capping subsystems in an integrated and controlled environment, thus enabling the processing of substrates in an efficient manner, while minimizing the exposure of the substrates to an external environment and minimizing the condensation of vapors while the substrate is processed by the cure and capping subsystems.

Abstract:

A free-standing riser system connects a subsea source to a surface structure. The system includes a concentric free-standing riser comprising inner and outer risers defining an annulus there between. A lower end of the riser is fluidly coupled to the subsea source through a lower riser assembly (LRA) and one or more subsea flexible conduits. An upper end of the riser is connected to a buoyancy assembly and the surface structure through an upper riser assembly (URA) and one or more upper flexible conduits, the riser also mechanically connected to a buoyancy assembly that applies upward tension to the riser. The riser may be insulated for flow assurance, either by a flow assurance fluid in the annulus, insulation of the outside of the outer riser, or both. The system may include a hydrate inhibition system and/or a subsea dispersant system. The surface structure may be dynamically positioned.
