Chips are tiny skyscrapers. Their circuitry can be more than 100 layers high, and each of those layers plays a key role in making sure the chip works as intended. Lower, so-called ‘critical’ layers make up the actual transistors at the heart of the microchip. These are the most complex layers with the smallest feature sizes. Higher up, larger metal interconnects supply power and route electrical signals to and from the transistors. For chipmakers, choosing the right lithography tool for each layer is key to making sure the final skyscraper is manufactured as cost effectively as possible.
