Electronics use wafer sizes from 100 to 450 mm diameter. The largest wafers made have a diameter of 450 mm, but are not yet in general use.en.wikipedia.org/wiki/Wafer_(electronics)Silicon wafers are typically available in a range of sizes, with the most common sizes being 2 inch 3 inch 4 inch 6 inch 8 inch 12 inch These sizes refer to the diameter of the wafer, which is measured in inches.www.universitywafer.com/silicon-wafer-diameters.h…
