Below are examples of what standard silicon wafers shipping containers look like. Both hard and soft plastic are available.
To increase yields to decrease prices, semiconductor manufacturers helped the industry evolve wafer diameters that are now 450mm!
For over 50 years, the semiconductor industry has striven, with great initial success, at greatly reducing the manufacturing cost to make transistors. One of the easiest ways of reducing transistor costs was to increase transistor yields from the silicon wafers that they were etched on. The future of silicon wafers diameters may be determined by the easy of handling and shipping. The larger the wafer, the heavier they weigh and greater storage areas, equipment are needed to support the wafers.

|200 mm (8 inch)||725 μm.||1992||53 grams||269|
|300 mm (12 inch)||775 μm||2002||125 grams||640|
|450 mm (17.7 inch)||925 μm||future||342 grams||1490|
|675-millimetre (26.6 in)||Unknown.||future|
It is interesting to note that say 200mm silicon wafer diameters are not exactly 200mm, but 7.9 inches! Why? The semiconductor industry was born in the United States which did not use the metric system. But as the rest of the world, specifically Japan started to manufacture semiconductors, the 200mm designation was used for 8 inch (7.9 inch) substrates. And now all diameters in inches are referred to their metric equivalent.
