Most wafers are made of silicon extracted from sand. The main advantage of using silicon is that it is rich in supply, being the most abundant element in nature, just after oxygen. Its environmentally friendly properties are an added bonus. Building an ingot, the 2012/2/28Ingot slicing.The ingot is cut into individual silicon discs called wafers. Each wafer has a diameter of 300mm and is about 1 mm thick. Wafers are polished until they have flawless, mirror-smooth surfaces. Intel buys manufacturing-ready wafers from its suppliers.

Silicon wafers are pieces of silicon, frequently derived from sand, that go through special machinery that etches the interconnections that actually make the chips onto them. Since most wafers are big enough to hold multiple chips, they're then cut into individual pieces.
