Next the finished Ingot is ground to a rough size diameter (a little larger than a finished wafer) and it is either notched or flatted along it's length to indicate the orientation of the Ingot. This is also a point when many inspections are made on the ingot to catch any major flaws or problems with resistivity etc. The 200mm and 150mm ingots at the LEFT are freshly pulled and have not yet been ground, notched or flatted.
