Intro and overview

The silicon found in sand is in the form of silicon dioxide. To make chips, manufacturers need pure silicon so the first step in the process is to separate the silicon from the oxygen molecules. The pure silicon needed to make silicon chips can have only one foreign atom for every billion silicon atoms. It must also be mono-crystalline form.
