Semiconductor Wafer Fabrication Quiz

A wafer is a thin slice of semiconductor material, such as crystalline silicon, used for the fabrication of integrated circuits and solar cells.

The term 'wafer' first appeared in the 1950s to describe a thin round slice of semiconductor material, typically germanium or silicon.

The Czochralski method is used to produce single-crystal ingots, which are then used to make silicon wafers.
