Secondary (smaller) flats indicate whether a wafer is either p-type or n-type. 200 mm (8-inch) and 300 mm (12-inch) wafers use a single notch oriented to the specified crystal axis to indicate wafer orientation with no indicator for doping type. Figure 3 shows the relationship between wafer type and the placement of flats on the wafer edge.
