Silicon Wafer Sizes and Area: 150mm / 200mm / 300mm / 450mm
Diameter, single-wafer area and area relative to the mainstream 300mm wafer across generations.
| Wafer diameter | Radius | Area (mm²) | Relative to 300mm |
|---|---|---|---|
| 150mm (6 in) | 75 mm | 17,671 | 0.25× |
| 200mm (8 in) | 100 mm | 31,416 | 0.44× |
| 300mm (12 in) | 150 mm | 70,686 | 1.00× (mainstream) |
| 450mm | 225 mm | 159,043 | 2.25× (not in volume production) |
Method & sources
Area = π×(diameter/2)², geometric calculation (rounded to whole mm²); relative area = size area ÷ 300mm area. 300mm is the current volume-production mainstream; 450mm has not reached volume production.
