First, though, that silicon must be purified. This is one of the most critical steps, because even a minute trace of impurities can cause chips to fail. Once in purified form, the silicon is formed into wafers, which are simply thin sheets crystalline material. Then, the CPU maker etches, or imprints, lines onto the surface of the wafer.
