High purity silica rocks, which can be found only in select mines around the world, are reduced to silicon metal in a special furnace. From this silicon metal, polycrystalline silicon of 99.999999999% purity is created, and this is the raw material used by Shin-Etsu to fabricate semiconductor grade single-crystal silicon wafers. Special crystal growing methods […]
Butte's REC Silicon facility has laid off 30 employees as part of a cost-cutting effort, the company announced Wednesday morning.
