A wafer is a slice of semiconductor or other material that is used in manufacturing microelectronics and/or display gadgets.

For microelectronic machine fabrication, theoretically a wafer could be scribed as the first major processing step. This would enable much physically smaller further processing equipment.

Types[edit]

  • Silicon
    • Silicon [100]
  • Silicon carbide
  • Gallium nitride
  • Indium phosphide
  • Glass
  • Sapphire

Composites[edit]

  • Indium gallium arsenide epiwafer on indium phosphide

Making[edit]

In making wafers, nearly half of the material is lost when sawing the wafers from the silicon boule.[1]
