  • Examining purification and certification strategies for high-purity C 2 F 6 process gas
    organic purity. The article outlines standard methodology and discusses supplemental testing methodology developed for benchmarking C quality beyond the current specifications. Ways that emerging methodologies may provide a standard on which to base future process improvements are addressed
  • Beta testing an in-line monitor for moisture measurement in inert gas lines
    of process steps increase the risks associated with moisture contamination, the semiconductor industry needs new techniques for controlling gas purity. Extensive beta-site collaboration is needed to develop products that can minimize contamination-related downtime, provide more knowledge about the moisture
  • The Logical Path - The Application of Ceramics to Diaphragm Pumps
    oxide ceramic manufacture and aluminum oxide ceramic has become particularly significant. By optimizing the time and temperature of sintering as well as the purity and particle size of raw material, quality has been improved and costs reduced. Precision parts, and the diaphragm head is one of them
  • Niobium (Nb) for Hot Concentrated Nitric Acid: Material Selection & Field Experiences with Nb-Shell & Tube Heat Exchangers (.pdf)
    The highly acid, oxidizing conditions in parts of nitric acid plants severely tax conventional materials such as high-purity aluminum and high-silicon stainless steel. Long-term field-testing of these materials along with tantalum, tantalum-25%tunsten and niobium showed excellent performance
  • Bellows let chip testers run hot and cold
    The S-170, made by Aseco Corp. in Marlboro, Mass., accepts chips loaded on two, four-track aluminum magazines, then singulates them into a large thermal soak chamber. Corrosion-resistant nickel bellows by Servometer, Cedar Grove, N.J., handle extreme temperatures in the chamber and are arrayed
  • PRODUCT ALLSTARS
    , and plasma-etch applications. A high-purity transducer is fully rated for NEMA 4 service. The Model 332 pressure sensor can be mounted on gas pads or in gas bunkers at semiconductor facilities. Available in pressure ranges from 0 30 to 0 5000 psi, the model has a compensated temperature range of 0
  • MICRO: Taking Control
    if it goes undetected. The problem is that given the nature of argon-driven metal sputtering using aluminum, aluminum/copper alloys, or titanium/titanium nitride alloys, the process has been largely unmeasurable in a manufacturing environment. Research at Infineon (Dresden, Germany), however, has armored
  • Porous Metal Handbook
    depends on the metal powder characteristics (composition, particle size, shape, purity, etc.) and the forming pressure. Porous metal parts differ from standard PM structural parts in that they are pressed at lower pressures and may tight mesh cuts of powder in order to achieve specified porosity
