Abstract: To measure a characteristic of a multimode optical fiber, a light pulse source produces a light pulse for transmission into the multimode optical fiber. A spatial filter passes a portion of Brillouin backscattered light from the multimode optical fiber that is responsive to the light pulse. Optical detection equipment detects the portion of the Brillouin backscattered light passed by the spatial filter.

Abstract: A tool that is usable in a well and may include an operator, a switch, a resilient device and an indexer. The switch may be configured to selectively communicate a first force to the operator, thereby actuating the tool. The resilient device may exert a second force. The indexer may cycle through a sequence of positions in response to alternating between the second force and a third force. The sequence includes a predetermined position configured to actuate the switch, thereby communicating the first force to the operator to actuate the tool.

A mechanism of the apparatus indicates when the first inductive coupler is substantially aligned with the second inductive coupler.

Abstract: A technique is provided for actuating devices deployed in a wellbore. The technique utilizes an actuator that cooperates with a downhole device, such as a well tool. The actuator has a phase change material that can be caused to undergo a phase change upon an appropriate input. The phase change of the material is used to provide the force necessary for actuation of the downhole device.

The technique includes measuring pressure at a plurality of points along at least a portion of the well without an intervention in the well and estimating a permeability profile along the portion of the well by use of the plurality of pressure measurements.

Abstract: This disclosure discusses cleaning of semiconductor wafers after the Chemical-Mechanical Planarization (CMP) of the wafer during the manufacturing of semiconductor devices. Disclosed is an alkaline chemistry for the post-CMP cleaning of wafers containing metal, particularly copper, interconnects. Residual slurry particles, particularly copper or other metal particles, are removed from the wafer surface without significantly etching the metal, leaving deposits on the surface, or imparting significant contamination to the wafer while also protecting the metal from oxidation and corrosion. Additionally, at least one strong chelating agent is present to complex metal ions in solution, facilitating the removal of metal from the dielectric and preventing re-deposition onto the wafer.

Abstract: Method for producing a metal silicon (oxy)nitride by introducing a carbon-free silicon source (for example, (SiH3)3N), a metal precursor with the general formula MXn (for example, Hf(NEt2)4), and an oxidizing agent (for example, O2) into a CVD chamber and reacting same at the surface of a substrate. MsiN, MSIo and/or MSiON films may be obtained. These films are useful are useful as high k dielectrics films.

Abstract: Silicon nitride film is formed on a silicon wafer mounted in a boat in an LPCVD tool by feeding a silicon source (SiH2Cl2, SiCl4, Si2Cl6, etc.) from an injector and feeding a mixed gas of monomethylamine (CH3NH2) and ammonia (NH3) as the nitrogen source from an injector. This addition of monomethylamine to the source substances for film production makes it possible to provide an improved film quality and improved leakage characteristics even at low temperatures (450-600° C.).

Abstract: Embodiments of the invention provide methods, systems, and apparatus for delivering gas in a liquefied state at a controlled rate. The liquefied gas may be transported in ton cylinders by placing the ton cylinder on a transportation pallet. The transportation pallet containing the ton cylinder may be placed on a heating saddle so that a surface of the cylinder is in contact with a surface of the heating saddle. Heating fluid may flow through the heating saddle, thereby heating the liquid in the cylinder through the cylinder walls. Furthermore, the vapor pressure of the gas in the cylinder may be monitored and maintained at a desired level by regulating the flow of heating fluid through the saddle. Therefore, embodiments of the invention allow the maintenance of gas flow rates in a cylinder without removing the cylinder from its transportation pallet.

A sample of a halosilane supply is contacted and reacted with an aqueous hydrofluoric acid solution to produce a liquid reaction mixture. Liquid from the liquid reaction mixture is evaporated under controlled temperature and pressure conditions to near dryness. The nearly-dry residue is prepared for spectral analysis. The presence of a detectable amount of at least one metal analyte is determined for the sample.

Abstract: An electric-arc welding process for assembling parts that are components of a motor vehicle, in which a consumable wire is used that is subjected to a cyclic mechanical movement. The wire is moved closer to and then further away from the parts to be welded so as to create a short arc between the end of the consumable wire and at least one of the parts to be joined. In this way, molten metal is deposited in order to progressively produce a welded joint between the parts.
