[Middle English wafre, from Anglo-Norman, variant of Old North French waufre, of Germanic origin.]


 
 

(1) A small, thin continuous-loop magnetic tape cartridge that has been used from time to time for data storage and specialized applications.

(2) The base unit of chip making. It is a slice taken from a salami-like silicon crystal ingot up to 12" (300mm) in diameter. The larger the wafer, the more chips produced in a single production pass, which comprises a series of photomasking, etching and implantation steps. Wafers are approximately 1/30th of an inch thick; however, the actual layers of transistors that make up the active circuitry are only a few microns deep.

Wafers started out being very small from one to three inches in diameter. Then came 100mm ingots (approximately 4"), followed by 125, 150, 200 and 300mm. Various different wafer sizes are used today, depending on the type of chip being made. See chip and wafer scale integration.

The Boule Is Sliced
The silicon ingot, which is known as a "boule," is sliced into wafers.

Different Sizes
The person at the top is holding 150mm wafers; in the middle 200mm; and 300mm at the bottom. .

Heating the Wafers
The red glow comes from a furnace that reaches 1000 degrees centigrade. The semiconductor wafers are baked in the oven to prepare them for the chip-making process.

In cooking, a wafer is a crisp, sweet, very thin, flat, and dry cake that is often used to decorate ice cream. Wafers can also be made into cookies with cream flavoring sandwiched between them. They frequently have a waffle surface pattern.

The word also refers to the special small round flat breads made for Anglican Holy Communion services; the word host is used in the Roman Catholic liturgy. These holy wafers often have an image of the crucified Christ imprinted on them.

In the spa towns of the Slovak Republic (e.g. Piešťany, etc.) special "spa wafers" (kúpeľné oplátky) are produced.

In the spa towns of the Czech Republic (e.g. Karlovy Vary, Mariánské Lázně, etc.) special "spa wafers" (lázeňské oplatky) are produced.

Christmas wafers are an Eastern European Roman Catholic Christmas tradition celebrated in Polish, Slovak, Lithuanian and Italian families during Wigilia (Christmas Eve Vigil).
