isotopically pure silicon-28 The currently produced isotopically pure silicon-28 waver are almost all epitaxial wavers: They have only a small top layer of pure Si-28. The bulk wavers are the ones which provide a 30-35 degree lower die temperature. isonics.com During 1999, Semiconductor manufacturers such as Advanced Micro Devices and Cypress Semiconductor started evaluation programs using silicon-28 epi wafers for microprocessor and memory applications. Additional manufacturers are expected to start evaluation programs this year. Bulk silicon-28 wafers are planned to be available by the end of the year 2000. These wafers are targeted for power semiconductor applications and applications where the maximum temperature reduction is necessary. Initial modeling studies have indicated that peak temperature reductions of up to 30oC may be possible in advanced microprocessors due to the higher thermal conductivity of silicon-28 bulk wafers. biz.yahoo.com We are continuing to develop our supply chain to demonstrate to potential customers that we can provide both epitaxial and bulk silicon-28 wafers at the appropriate quality, quantity, and price in order to make silicon-28 the material of choice in applications where its superior heat conductance properties can be fully exploited. During the next twelve months we plan to grow our present capacity of 100,000 epitaxial wafers per year to over 500,000. We also plan to produce an initial quantity of 1,000 bulk wafers and to grow that capacity to over 100,000 per year over the next 24 months. some more: mpg.de theregister.co.uk Regards Hans.
