4. How chips are made
Inside computers, the CPU is a microprocessor chip. Most processors (1) are made … of silicon. This material can be obtained from beach sand and works well because it’s a semiconductor of electricity. Manufacturers make large crystals (2) of high-quality silicon and then each crystal (3) is cut … with chemicals, into slices less than a millimetre thick. These slices, called wafers, (4) are treated … with chemicals. In the next step they are cut into individual chips.
Gaps and light before millions of transistors and very small wires (4) are built … onto the chip in several layers.
After that, the chip (5) is tested … many times to ensure that all switches and circuits work correctly. Finally, each chip (6) is inserted … into a protective package, which allows the processor to connect to other devices on the motherboard of the computer.
