Wafer Manufacturing Process: Each Step Matters
This is because much of the material is removed during the smoothing process, to get to as flat a surface as possible. How It's Done. The rough wafer adheres to a vacuum which holds it in place before we use equipment to grind minuscule layers from the surface of the wafer. This is done gradually to avoid damaging the wafer. Why It's Important
