AMD samples isotopically pure wafers
Silicon-28 gives faster performance, isotypically
Isonics Corporation, which has a licence with Yale University to intellectuall property rights for isotopically-pure silicon-28, said it has shipped wafer samples to AMD. According to Isonics, AMD will test the performance of wafers using the technology on device performance, evaluation of overall chip yield and speed sorting, comparing that to ordinary silicon epitaxial wafers. Lab tests by Isonics show that silicon-28 has a 50 per cent higher thermal conductivity than natural silicon. Silicon-28 allows for higher density integrated circuits (ICs) with better performance and improved chip yields. Isonics also has a licence from Yale for other isotopically pure substances including germanium, gallium arsenide and other semiconductors, typically. Or topically. ®
