Web• Mask size can get unwieldy for large wafers. • Most wafers contain an array of the same pattern, so only one cell of the array is needed on the mask. This system is called Direct Step on Wafer (DSW). These machines are also called “Steppers” • Example: GCA-4800 (original machine) • Advantage of steppers: only 1 cell of wafer is needed A wafer is a crisp, often sweet, very thin, flat, light biscuit, often used to decorate ice cream, and also used as a garnish on some sweet dishes. Wafers can also be made into cookies with cream flavoring sandwiched between them (e.g., Oreo). They frequently have a waffle surface pattern but may also be patterned with insignia of the food's manufacturer or may be patternless. Some chocolate ba…
