- Silicon wafers are made through the following steps12:
- Refine pure elemental silicon from ordinary sand (which is mostly silicon dioxide, also called "silica").
- Melt the silicon and add a seed crystal.
- Grow the crystal by rotating it in the crucible.
- Pull the crystal from the crucible.
- Extract the fully formed crystal with a residue of melted silicon.
- Cut slices from the large crystal; these slices are blank, rough-cut silicon wafers.
- Polish the surface of each silicon wafer.

Wafer (electronics) - Wikipedia
Wafers are formed of highly pure, nearly defect-free single crystalline material, with a purity of 99.9999999% (9N) or higher. One process for forming crystalline wafers is known as the Czochralski method, invented by Polish chemist Jan Czochralski. In this process, a cylindrical ingot of high purity monocrystalline semiconductor, such as silicon or germanium, called a boule, is formed by pulli…
