Ch 1 · From beach sand to pure silicon
steve From Sand to Silicon
Melt the sand to grow a crystal bright, (growing so bright!) / Slice it thin to make the circuits glow! (yeah, that's right!)
Fun Fact
Silicon purity: If a silicon wafer were the size of the United States, the maximum allowed impurity would be smaller than a single coin.
Glossary
silicon (noun)
A chemical element of atomic number 14, a metalloid widely used in making electronic circuits. Raw silica sand is chemically refined to achieve an ultra-high purity of 99.9999999 percent.
