  • Patent number: 7172096
    Abstract: A system for dispensing liquid to a manufacturing process from a container including an outer container and a flexible inner container occupied by the liquid. A flow passage provides fluid communication between an interior of the inner container and the manufacturing process. A pressurized fluid source is in fluid communication with a space between inner walls of the outer container and the inner container. The pressurized fluid source causes fluid under pressure to flow into the space between the inner walls of the outer container and the inner container to force liquid out of the inner container to the manufacturing process via the flow passage. A pressure sensor is positioned to sense pressure in the flow passage. A controller responsive to the pressure sensor controls the pressure in the flow passage by modulating the pressure from the pressurized fluid source.

  • Patent number: 7160815
    Abstract: A method and composition for removing silicon-containing sacrificial layers from Micro Electro Mechanical System (MEMS) and other semiconductor substrates having such sacrificial layers is described. The etching compositions include a supercritical fluid (SCF), an etchant species, a co-solvent, and optionally a surfactant. Such etching compositions overcome the intrinsic deficiency of SCFs as cleaning reagents, viz., the non-polar character of SCFs and their associated inability to solubilize polar species that must be removed from the semiconductor substrate. The resultant etched substrates experience lower incidents of stiction relative to substrates etched using conventional wet etching techniques.

  • Patent number: 7160590
    Abstract: A multilayer web article, including a first layer of a porous material, e.g., Tyvek® film, and a second layer overlying and sealed to the first layer. The second layer is non-porous to passage of gas therethrough and includes a peelable film, e.g., of polyethylene, in contact with the first layer of porous material. The peelable film permits peeling removal of the second layer from the first layer to expose the first layer of porous material for passage of gas therethrough. In a specific construction, the web article constitutes one of opposedly facing panels of a lay-flat bag article, in which the facing panels are bonded to one another along superposed edges thereof. After pressurization integrity testing of the bag, the peelable film is peeled away to enable steam - and/or ETO-sterilization of the bag and its contents to be carried out.

  • Patent number: 7152781
    Abstract: The present invention is a manufacturing system including a hazard zone and a non-hazard zone. The system includes a storage device, located in the hazard zone, for electrically storing information. The system further includes a communication device, also located in the hazard zone, for storing information to and reading information from the storage device. In the non-hazard zone, a controller is in electrical communication with the communication device. The controller controls the system based on information read from the storage device by the communication device. To limit electrical energy passing to the communication device, an intrinsic safety barrier located in the non-hazard zone is connected between the communication device and the controller device.

  • Patent number: 7129519
    Abstract: The present invention relates to a semiconductor processing system that employs infrared-based thermopile detector for process control, by analyzing a material of interest, based on absorption of infrared light at a characteristic wavelength by such material. Specifically, an infrared light beam is transmitted through a linear transmission path from an infrared light source through a sampling region containing material of interest into the thermopile detector. The linear transmission path reduces the risk of signal loss during transmission of the infrared light. The transmission path of the infrared light may comprise a highly smooth and reflective inner surface for minimizing such signal loss during transmission.

  • Patent number: 7119418
    Abstract: Supercritical fluid-assisted deposition of materials on substrates, such as semiconductor substrates for integrated circuit device manufacture. The deposition is effected using a supercritical fluid-based composition containing the precursor(s) of the material to be deposited on the substrate surface. Such approach permits use of precursors that otherwise would be wholly unsuitable for deposition applications, as lacking requisite volatility and transport characteristics for vapor phase deposition processes.

  • Patent number: 7104292
    Abstract: A gas storage and dispensing system, including multi-vessel arrays of gas dispensing vessels that require successive change-over to provide ongoing supply of gas to a gas-consuming process, with a pump coupled in gas flow communication with the array. The system is provided with capability for time delay auto-switchover sequencing of the switchover operation in which an endpoint limit sensing of an on-stream gas dispensing vessel is responsively followed by termination of gas flow to the pump, inactivation of the pump, autoswitching of vessels, reinitiation of gas flow to the pump and reactivation of the pump. The system minimizes the occurrence of pressure spikes at the pump outlet in response to pressure variation at the pump inlet incident to switchover of gas supply from one vessel to another in the multi-vessel array.

  • Patent number: 7090554
    Abstract: A flat-panel display is fabricated by a process in which a spacer (24) having a rough face (54 or 56) is positioned between a pair of plate structure (20 and 22). When electrons strike the spacer, the roughness in the spacer's face causes the number of secondary electrons that escape the spacer to be reduced, thereby alleviating positive charge buildup on the spacer. As a result, the image produced by the display is improved. The spacer facial roughness can be achieved in various ways such as providing suitable depressions (60, 62, 64, 66, 70, 74, or 80) or/and protuberances (82, 84, 88, and 92) along the spacer's face.
