Wafer
Updated: 10/17/2017 by Computer Hope
More commonly known as a silicon wafer, a wafer is a single thin slice of a crystal ingot that is precisely cut using a diamond saw and chemically polished. The silicon wafers are approximately 1/30th-inch to 1/50th-inch thick and 3 to 6 inches in diameter. Using these wafers, a manufacturer can place anywhere from 10 to several hundred semiconductors or ICs onto it, which are later cut out and used in computers and other electronics. The picture shows an example of a silicon wafer with multiple silicon chips.
