This article is about wafers in semiconductor industry. See Wafer (cooking) for the original meaning of the word.

In microelectronics, a wafer is a thin slice of semiconducting material, such as a silicon crystal, upon which microcircuits are constructed by diffusion and deposition of various materials. Wafers are thus of key importance in the fabrication of semiconductor devices. They are made in various sizes ranging from 1 inch (25.4 mm) to 300 mm (11.8 inches).

Note: Millions of individual circuit elements, constituting hundreds of microcircuits, may be constructed on a single wafer. The individual microcircuits are separated by scoring and breaking the wafer into individual chips (" dies").

Wafers can also be made into biscuits with cream flavoring sandwiched between them. The word also refers to the special wafers made for Ca
Wafer mountingWafer mounting is a step that is performed during the die preparation of a wafer as part of the process of semiconductor device fabrication. During this step, the wafer is mounted on a plastic tape that is attached to a ring. Wafer mounting is performed r	Wafer testingWafer testing is the a step performed during semiconductor device fabrication. During this step, performed before a wafer is sent to die preparation, all individual integrated circuits that are present on the wafer are tested for functional defects by app
