Ultra-high-purity Silicon for Infrared Detectors: A Materials Perspective.
MISSING :13 pages
To assess the supply status of ultra-high-purity silicon for national defense needs, the U.S. Bureau of Mines conducted a general study of the availability of materials and processing technology for silicon used in the manufacture of infrared (ir) detectors from raw materials to the highly advanced device state. The United States possesses all of the raw materials and processing technology for ir detector-grade silicon production, but does not produce at all of the processing stages on a regular basis. Consequently, the United States continues to rely on foreign sources for some of these critical materials.
