-### How is it manufactured?
+A silicon wafer is made from single-crystal silicon, which is derived from high-purity sand.
+#### How is it manufactured?
 The process involves purifying the sand, melting it, and re-crystallizing it into a large, pure silicon ingot (Czochralski process). This ingot is then sliced into thin discs, which are polished to a mirror-like finish to form the wafer.
