NFF Product 1. Winning the global race for solar. While there are numerous contestants in the race to produce low-cost solar silicon, the chemistries involved can be grouped into three categories: new Siemens-like processes, new approaches to reduction of silica, and upgrades of metallurgical-grade silicon. This review is focused on the thermo-chemistries being employed in the last two categories, with emphasis on removal of boron and phosphorous, as these elements are the two most difficult to remove from silicon by unidirectional solidification.
Historically, the photovoltaic (PV) industry relied on off-spec electronic-grade silicon (e-Si) as its primary raw material. That silicon, produced through the Siemens Process, is both costly and far purer (nine 9s) than that necessary for PVs.1 With growing demand, it was only a matter of time before there was a shortage of silicon for PVs. Impurities in the Silicon Submerged Arc Furnace Phosphorous is far less volatile in molten iron than silicon.
How sand is transformed into silicon chips. The deserts of Arizona are home to Intel's Fab 32, a $3billion factory that's performing one of the most complicated electrical engineering feats of our time. It's here that processors with components measuring just 45 millionths of a millimetre across are manufactured, ready to be shipped out to motherboard manufacturers all over the world. Creating these complicated miniature systems is impressive enough, but it's not the processors' diminutive size that's the most startling or impressive part of the process.
It may seem an impossible transformation, but these fiendishly complex components are made from nothing more glamorous than sand. Such a transformative feat isn't simple. The production process requires more than 300 individual steps. We've taken an in-depth look at Intel's manufacturing method and distilled the whole process into 10 stages. Step one: Converting sand to silicon Step two: Creating a cylindrical crystal Step three: Slicing the crystal into wafers. Live tweets: Occupy DC arrests.
