 Isonics Partners with Major Wafer Manufacturer
 Isonics Corporation (NASDAQSC:ISON/ISONW, FRANKFURT: IO9) announced that it has entered into an silicon-28 marketing agreement with one of the world’s leading wafer manufacturers.
 
 The agreement calls for Isonics to supply silicon-28 raw materials and for the partner to produce silicon-28 epitaxial wafers and sample them to interested customers worldwide. The wafers will be manufactured in the partner’s U.S. facility.
 
 Dr. Stephen Burden, Isonics’ Vice President of Semiconductor Materials, commented, “This relationship is an important step towards commercialization of silicon-28. Our wafer partner is a qualified supplier with all of our target customers. Supplying silicon-28 state-of-the-art wafers in 200 and 300 mm diameters through an existing supplier is necessary for a number of companies that want to evaluate silicon-28. Should demand for commercial quantities of epitaxial wafers result from this effort, we would be in an excellent position to supply them in a short period of time.”
 
 Isonics is a world leader in isotopically engineered materials and produces isotopically pure silicon-28 chemicals and wafers for the semiconductor industry. Isonics also markets and sells stable isotopes for the health care industry such as carbon-13 for diagnostic breath tests and drug design, and oxygen-18 for positron emission tomography (PET) imaging. Stable isotopes can be thought of as ultra pure materials. This high degree of purification provides enhanced properties as compared to natural materials.
