  • Apparatus for removing noble metal contamination from liquids
    Patent number: 6365042
    Abstract: Silicon is employed as a reducing agent in an acid bath to adsorb noble metals present as contaminants in the acid. In the manufacture of silicon devices for electronic memory and other devices, polonium-210 is adsorbed by silicon getters to reduce soft error rate attributable to alpha particle emissions from the radioactive polonium. The noble metals in addition to polonium which can be plated onto silicon using the disclosed method are gold, silver, platinum, copper, palladium, mercury, selenium and bismuth.
    Type: Grant
    Filed: June 2, 1997
    Date of Patent: April 2, 2002
    Assignee: Micron Technology, Inc.
    Inventors: Troy Sorensen, Eric Grieger
