    operations to perform process setup, in-line quality control, and product certification. Magnum high-capacity filter cartridges allow users of bag filters to achieve cartridge-level performance without having to change hardware. The large, 6-in.-diam absolute-rated cartridges accommodate most size 1 and size...

    specifically targets molecular acids, bases, and condensables. The unit features a serial flow design and a small footprint, which allows for quick and easy installation. Several in-series filters can be optimized for specific requirements, allowing operators to remotely monitor filter lifetimes...

  • Photos for "Astronomers Discover "Feeding" Mechanism For Black Holes"
    . The WFPC2 image was taken in October 1994 using a near-infrared filter (8269 Angstroms), and acquired from the HST Data Archive. The NICMOS image was taken in August 1998 using a filter with a wavelength of 16,000 Angstroms. This image was taken as part of a study of 24 similarly active galaxies...

    back into the facility and reused. "We're hoarding our water molecules," quips Egermeier. "We don't have to pay for any sewer discharge permit, don't have to buy a lot of water. The only costs we have are in the operation of the filter and the regeneration loop, where we take some chemicals and put...
  • Meeting the challenge of submicron defect characterization on final-polished wafers
    . However, using an improved polishing process, we were able to produce very smooth wafers (Ra = 1.51 A, measured using a Zygo with an 80-um filter) on which particles as small as 0.08 um were detected clearly by the 6420, with a signal-to-noise ratio of approximately 5:1. In another experiment, a 6220...

    around the world and long-term repeatability of better than half an angstrom, and the reality is that with some effort you could do that. Now people are getting to some 30-A gates, and they're saying you need to do twice as good as that. You face the added complications that electrical performance...
