As far as I know, no other company can do anything that involves Silicon-28, unless Isonics grants them a license, at least that is the way I read this old news story about Isonics and the Yale Patents. A service of Semiconductor Business News, CMP Media Inc. Story posted 9 a.m. EST/6 a.m., PST, 4/19/99 Daily news for semiconductor industry managers Isonics to use Yale patents to develop advanced wafer technology GOLDEN, Colo. -- Isonics Corp., a materials technology company here, has received exclusive rights from Yale University to patents covering semiconductor devices based on isotopically engineered materials. These patents cover silicon, germanium, gallium arsenide and other isotopically pure semiconductors and are the basis for Isonics' silicon-28 wafer development and commercialization. The patents claim that isotopic purity yields improved thermal conductivity, among other properties of critical importance to chip makers. "We are sufficiently convinced of the scientific validity and the commercial opportunity presented by isotopically engineered semiconductors to move forward with this agreement," said Isonics president and CEO James E. Alexander. Isonics is trying to commercialize silicon-28, which is being used in research at several universities and semiconductor manufacturers. The company has formed a partnership with Eagle-Picher Industries to develop a low-cost domestic source for the production of the isotope. With the Yale patents, "the final objective is the acceptance of silicon-28 by a semiconductor manufacturer and full-scale production of devices using our technology," said Alexander. "We are now focusing our efforts more sharply on this goal." Isotopically pure silicon-28 has 50% higher thermal conductivity than natural silicon, according to laboratory tests. Independent modeling studies have demonstrated a 20 to 30 degree C reduction in peak operating temperature as a result of using silicon-28. Isonics believes that this propery will make silicon-28 attractive to chip makers because it will increase performance and improve chip yields. "Silicon-28 can provide these benefits over standard silicon, and can be used without any changes in existing semiconductor manufacturing processes," said Alexander. ___________ Note: Prof. T-P. Ma's patent is "Isotopically Enriched Semiconductor Devices", U.S. Patent No. 5442,191, Aug. 1995. [ Next Thread | Previous Thread | Next Message | Previous Message ] |
