ASML's $250 million 'printer,' the secret behind Nvidia chips

ASML is the most valuable company in Europe thanks to its dominance of lithography systems. These are huge "chip-printing" machines, which cost $250 million per machine and are essential to companies driving the AI boom. Take a look at how the Dutch company has grown.

What is driving the demand for ASML's printers?

ASML has a monopoly over the machines that use extreme ultraviolet light (EUV), which are used to manufacture the most advanced semiconductors. However, rivals from China and the U.S. have been working on alternatives. ASML is ASML because of the rapid advances in AI, and the global expansion of data centres.

The technology: HUGE MACHINES WORKING ON NANOSCALE

The machines, which are the size of school buses and weigh 150 tons, use an intricate system of mirrors, lasers, and magnets to create microscopic circuitry on silicon wafers for chip production.

The pattern of light is projected onto silicon wafers containing up to 100 AI chips. This allows them to map circuitry layers with unprecedented precision.

The EUV wavelength measures?13 nanometers. A?human hair measures between 80,000 to 100,000 nanometers in thickness.

According to Luc Van den Hove of the Interuniversity Microelectronics Centre, a Belgian company that developed the technology in collaboration with ASML, the machines provided "patterning accuracy, scalability, and energy efficiency", which were essential for advanced chip manufacturing, and AI chips, in particular.

LENSES AND MIRRORS

The German industrial company Trumpf uses some of the strongest lasers to blast tin droplets 50,000 times a second. The light is guided into the heart by a system of mirrors manufactured?by German optical equipment maker Zeiss. They have surfaces that are smoother than the ones used in space telescopes.

The table that holds the wafers levitates on magnets, and accelerates and slows down at a rate between 70 and 80 meters per second.

How are ASML Systems?Delivered?

The EUV machines will be assembled in the Netherlands and then transported on 747 cargo aircraft to the plants of TSMC in Taiwan (which manufactures Nvidia chips), Samsung, SK Hynix, Micron, Intel, and Rapidus, in the U.S. Analysts predict that ASML will need to increase the number of such systems in 2026 or 2027.
