- 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.
