  • Silicon on Sapphire (SOS)
    Silicon on sapphire (SOS) is a hetero-epitaxial process wherein a thin layer of silicon is 'grown” on a sapphire (Al2O3) wafer. SOS is part of the silicon on insulator (SOI) family of CMOS technologies. Silicon on sapphire is primarily used in military and space applications because of its inherent
  • Thin Film Resonator Technology
    piezoelectric transducers using CdS or ZnO, were first used in microwave delay lines as a means of generating the high frequency wide bandwidth time delays required by radar signal processing applications. These delay lines required piezoelectric plates bonded to the delay medium (which was often sapphire

  • MICRO:New Technologies-Analysis & Metrology, by Patrick J. McCann, p.93 (July '99)
    of such materials as sapphire, calcium fluoride, or zinc selenide. The signal from a detector facing the laser provides information on the identity and concentration of the molecules present as the laser is tuned across the relevant absorption bands. Semiconductor lasers fabricated using epitaxially
  • Science Update
    with a sensor that uses near-infrared-reflectance spectroscopy to take readings through a sapphire "window" on its bottom. Initial field trials have demonstrated an ability to measure moisture, organic carbon, and total nitrogen in soils. Data from on-the-go soil analyses particularly of important
  • MICRO: 'Round the Circuit
    of synthetic sapphire to create a novel method of manufacturing microchips. "We've developed a very fast and cost-effective way of getting data on and off a chip without using wire," reports Andreas Andreou, a department professor and director of the research lab. The team uses the same fiber
  • Medical Device Link . Spotlight on Microcomponents
    the creation of statistically defined production processes, and parts and features are verified by means of advanced vision system technology. Remmele Engineering Inc., Micro Machining Div. , Big Lake, MN, USA. Synthetic sapphire, ruby, ceramic, and metal-carbide materials are machined to tolerances
