9. Fabrication Process Flow: Basic Steps • The integrated circuit may be viewed as a set of patterned layers of doped silicon, polysilicon, metal, and insulating silicon dioxide. • The process used to transfer a pattern to a layer on the chip is called lithography. Since each layer has its own distinct patterning requirements, the lithographic sequence must be repeated for every …

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.
