Since the chips are so small, hundreds are made on a single silicon wafer at once. After all the patterns have been faithfully reproduced on to the chips, the wafer is sliced up into individual chips.

According to Time, waffles may have evolved from communion wafers: In fact, the familiar "honeycomb" pattern that appears on waffles may have been designed to represent "interlocking crosses." ...

Photolithography uses light to transfer a pattern of features from a mask to a light-sensitive chemical photoresist on a semiconductor wafer. As the pattern is transferred, it is reduced in scale ...

The equipment is used to print fine circuit patterns on semiconductor wafers. Japanese manufacturers once had a monopoly on the market for lithography systems, but they were overpowered by ASML ...
