Silicon wafer is utilized in the production of integrated circuits and is also used as a substrate for microelectronic devices. Various types of solar cells are also made from Silicon wafer. This type of wafer has various applications. And for each application, there is a specific wafer diameter that needs to be followed. To guide you, we made a list of the different diameters available for silicon wafers:

Silicon Wafer

A Silicon wafer is made from a highly pure, almost defect-free single crystal material, which is processed through the float zone method. This method allows the wafers to grow at a higher rate, lowers the oxygen levels, and has precise dopant control, which reduces defects and helps produce an efficient and effective Silicon wafer.

Wafer Diameters

Silicon wafers have different diameters from 1 inch (25.4 mm) to 17.72 inches (450mm). Its size is continuously increasing over the years to help enhance performance while lowering costs. The goal is to produce wafers which are thick enough to hold up its weight without breaking during handling. Wafer thickness is concluded through the mechanical strength of the material applied.

  • 1-inch (25 mm)
  • 2-inches (51 mm). Thickness of 275 µm.
  • 3-inches (76 mm). Thickness of 375 µm.
  • 4-inches (100 mm). Thickness of 525 µm.
  • 4.9-inches (125 mm) Thickness of 625 µm.
  • 150 mm (5.9 inches) Thickness of 675 µm.
  • 200 mm (7.9 inches) Thickness of 725 µm.
  • 300 mm (11.8 inches) Thickness of 775 µm.
  • 450 mm (17.7 inches) Thickness of 925 µm
