Refers to the single crystal silicon wafers

By ordinary silicon salad is made refined but become, is the most commonly used semiconductor materials, according to its diameter is divided into 4 inches, 5 inches and 6 inches, 8 inches specifications, such as the recent developed 12 inches or more large size, the greater the wafer, the same wafer can produce Ic is much, can reduce cost, but higher material technology and production technology.
