The 400 million ASML "printers" key to the AI chip boom

ASML is Europe's most valuable firm thanks to its dominance of lithography systems. These are?huge?chip printing? machines that cost up to $400 million and are essential to companies driving the?AI boom.

Chipmakers have expanded their capacity quickly due to AI advances and the global expansion of data centers. ASML supplies memory chip makers such as SK Hynix and Micron, as well to TSMC which manufactures chips for Nvidia. In the middle of the product range, the company faces new competitors from China. It is also being pressured by the United States regarding exports of certain tools to?Asian nations. The Dutch company's success is due to the innovative technology it uses.

How to tell apart your DUV, EUV and High NA

ASML is a leading manufacturer of deep ultraviolet (DUV), extreme ultraviolet (EUV), and lithography machines. These machines are named after the wavelengths of light that they use to zap the microcircuitry of chips on silicon wafers.

ASML's market share in the DUV segment, where tools that cost around $60 million each are made to produce chips for industrial and consumer electronics, is above 80%. This puts it ahead of its Japanese rivals Nikon and Canon.

It is the only company in the world that has the monopoly on the EUV technology. However, rivals from China and the United States are trying to create alternatives. Standard EUV tools cost about $200 million, and are used in the production of AI chips and cutting-edge memory.

ASML is testing its newest "High NA", EUV tools. These will be used in new generations of AI chip with smaller features over the next five years. So far, only a few have been produced. Each one is estimated to cost between $350 million and $400 million.

The technology: HUGE MACHINES WORKING ON NANOSCALE

The standard EUV machine for Nvidia chip production is about the size and weight of a school bus. It uses a complex system that includes lasers, magnets and mirrors to create microscopic circuitry on silicon wafers.

The AI chips are mapped out by shining light patterns onto silicon wafers. Each wafer contains about 100 AI chips.

The EUV wavelength measures 13.5 nanometers. A human hair is between 80,000 and 100,000 micrometers thick.

LENSES AND MIRRORS

The German industrial company Trumpf uses some of the most powerful lasers to blast tin droplets at a rate 50,000 times per sec. The light is guided into the heart by a system of mirrors manufactured by German optical systems maker Zeiss. These mirrors have surfaces that are smoother than those found in space telescopes. They are also kept in vacuum.

Magnetically levitated stage move wafers faster than 3 meters/second, with acceleration and deceleration forces more than 15x that of gravity.

How are ASML's huge machines delivered?

The EUV machines, which are assembled in Holland, are then packaged into 40 containers and transported by cargo planes to the customer's chip fabrication plant. ASML expects to sell 65 systems this year, and 85 by 2027.
