Tech help on heat load please.

Can anyone tell me if they think there is validity in this approach to dealing with heat build-up?

According to the company, AMD and Cypress are evaluating it. Also, one of the Cypress VPs is on their Board.

Max Planck Institute Study Confirms Superior
Thermal Conductivity of Isotopically Pure Silicon

GOLDEN, Colo.--(BUSINESS WIRE)--June 21, 2000--Isonics Corporation
(OTCBB:ISON/ISONW) A
new study by the Max Planck Institute of Germany has confirmed the higher thermal conductivity of
isotopically pure silicon-28.

In the June 19 issue of Solid State Communications, the authors reported the steady-state thermal
conductivity
of small diameter, silicon-28 single crystals and confirmed the 60% improvement in room
temperature
thermal conductivity and estimated that the improvement would persist to several hundred degrees.
At lower
temperatures, the thermal conductivity increased up to 600% higher than natural silicon and 2.5
times higher
than natural diamond. The full text of the article may be found on Isonics' website
www.isonics.com.

Dr. Stephen Burden, Isonics' Vice President for Semiconductor Materials, remarked, ``This study,
by one of
the world's premiere research institutes, should eliminate any remaining doubt that significant
improvements
over natural silicon can be achieved. The Eagle-Picher pilot plant is now in operation and is
expected to
deliver commercial quantities of silicon-28 by the end of the year. We expect to have initial
quantities of 200
mm bulk silicon-28 wafers available for customer testing early next year.''
