Silicon Wafer Processing

Hundreds of memory chips are etched onto each wafer. Pure single-crystal cylinders of silicon are sliced into thin, highly polished wafers less than one-fortieth of an inch thick. Hundreds of memory chips are etched onto each wafer, while for processor chips, perhaps only ten to 50 devices will fit on one wafer.

Design. The way a chip works is the result of how a chip's transistors and gates are designed and the ultimate use of the chip. Design specifications that include chip size, number of transistors, testing, and production factors are used to create schematics—symbolic representations of the transistors and interconnections that control the flow of electricity though a chip.
