Key Takeaways
Introduction to ASML Holding
ASML Holding, headquartered in the Dutch city of Veldhoven, operates behind the scenes but drives the digital age forward. Few companies embody modern innovation like ASML Holding, a cornerstone of global technology.As the world’s leading supplier of photolithography machines—equipment essential for producing advanced microchips—ASML Holding plays a critical role in powering the devices we use daily, from smartphones to AI systems. Its machines are the linchpin in the semiconductor supply chain, enabling manufacturers to create the ever-smaller and more powerful chips that drive technological progress.
What ASML Holding Does
ASML Holding specializes in photolithography, a process used to etch intricate patterns onto silicon wafers. These patterns form the foundation of microchips, which power everything from laptops to cars. Among its offerings, ASML Holding is uniquely positioned as the sole supplier of extreme ultraviolet (EUV) lithography machines—an advanced technology crucial for manufacturing the most cutting-edge chips. EUV lithography allows manufacturers to produce chips with transistor sizes below 4 nanometers, enabling higher performance and energy efficiency.1This dominance in high-end lithography makes ASML Holding indispensable to semiconductor giants like Taiwan Semiconductor Manufacturing Company, Samsung, and Intel. Without ASML Holding’s machines, the semiconductor industry would be unable to meet the demands of the modern digital economy.
How ASML Holding Reached EUV Mastery
The journey to ASML Holding’s EUV technology was an odyssey—a decades-long, high-stakes gamble that nearly faltered under its own ambition. The project began more than 30 years ago and has since consumed more than $9 billion in research and development funding.2 EUV lithography required unprecedented advances in fields like optics, material science, and engineering. For example, ASML Holding partnered with Carl Zeiss, a German optics company, to develop ultra-flat mirrors, an essential component of the system. These mirrors are so precise that even microscopic imperfections could render them unusable.Major semiconductor companies, including Intel, Samsung, and Taiwan Semiconductor Manufacturing Company, played a crucial role in EUV’s development by providing early funding and technical collaboration. In 2012, these firms collectively acquired a 23% equity stake in ASML Holding to help fund the project, highlighting the critical importance of this technology to the industry.3 Despite this, EUV faced immense skepticism during its early years. The complexity of the technology led many to doubt whether it would ever be commercially viable. However, ASML Holding’s persistence and partnerships ultimately overcame these challenges, culminating in the first commercial EUV machines being delivered in 2010 and reaching broader adoption by 2020.
How ASML Holding’s Machines Work
At the heart of ASML Holding’s innovation is the EUV lithography machine, a marvel of engineering complexity. This machine uses laser pulses to vaporize droplets of molten tin at a rate of 50,000 times per second. The resulting plasma emits extreme ultraviolet light, which has a wavelength of just 13.5 nanometers—short enough to print incredibly dense patterns onto silicon wafers.4The process requires an extraordinary level of precision. EUV light is directed using ultra-flat mirrors developed in collaboration with specialized optics manufacturers. These mirrors are so precise that if scaled to the size of Germany, their imperfections would be smaller than a millimeter. The light is then used to transfer patterns onto the wafer through a photomask, enabling the production of billions of transistors in a space smaller than a fingernail.While EUV machines are ASML Holding’s most advanced offering, the company also produces deep ultraviolet (DUV) lithography machines, which operate at larger wavelengths (between 193 and 248 nanometers).5 DUV technology is less advanced than EUV but remains critical for producing slightly older chip designs and is widely used in manufacturing processes.Chinese firms, unable to access EUV machines due to export restrictions, have heavily relied on ASML Holding’s DUV machines to sustain their semiconductor manufacturing capabilities. These machines allow Chinese manufacturers to produce chips at less advanced nodes but still competitive levels for many applications.6
High Numerical Aperture and Moore’s Law
ASML Holding’s breakthroughs have single-handedly kept Moore’s Law alive, sustaining the relentless doubling of transistors on chips every two years—a feat once thought impossible at today’s atomic scales. This doubling is essential for the continuous improvement of computing power and energy efficiency. Without ASML Holding’s EUV machines, producing chips with such high transistor density would be impossible.Moore’s Law, named after Intel co-founder Gordon Moore, has driven innovation for decades, but sustaining it has become increasingly challenging as chip features approach atomic scales. To continue Moore’s Law, ASML Holding is now working on high numerical aperture (NA) EUV lithography machines.High NA technology is lithography’s next frontier, poised to unlock unprecedented precision and enable the kind of breakthroughs that redefine industries. It uses a larger lens aperture to capture more EUV light, thereby improving resolution and allowing the printing of even smaller features on silicon wafers.This advancement is expected to enable chipmakers to manufacture nodes below 2 nanometers, supporting the next wave of innovations in AI, quantum computing, and advanced connectivity technologies.7 The first high NA EUV machines are slated to be delivered in 2025, marking a critical milestone in the semiconductor industry’s roadmap.
Why ASML Holding is Indispensable
As previously mentioned, ASML Holding’s technology has become the linchpin of Moore’s Law, which predicts that the number of transistors on a chip doubles roughly every two years.Currently, only a few companies, including Taiwain Semiconductor Manufacturing Company, Samsung, and Intel, own ASML Holding’s EUV machines. This limited availability underscores the machines’ complexity and cost, with each unit priced between $150 million and $400 million.8 Moreover, geopolitical factors, such as export restrictions on selling EUV technology to China, further highlight ASML Holding’s strategic importance to the global technology ecosystem.The restrictions on EUV exports to China are part of broader trade policies aimed at limiting China’s ability to develop cutting-edge semiconductors for potential military and technological dominance. However, Chinese firms have been purchasing significant numbers of DUV machines, which are not subject to the same restrictions.While DUV technology cannot match the precision of EUV, it still enables the production of chips at nodes up to 7 nanometers with advanced multi-patterning techniques. This has allowed Chinese manufacturers to stay competitive in less-demanding sectors like consumer electronics and automotive chips.
Can China Develop EUV Technology?
The question of whether China can independently develop EUV technology in the near-term is a topic of significant speculation. EUV machines are among the most complex technologies ever created, requiring cutting-edge expertise in optics, materials science, and engineering. For example, the ultra-flat mirrors used in EUV machines are produced by only a handful of specialized companies, and the laser systems involve unprecedented precision.Experts believe that while China is making substantial investments in semiconductor technology, replicating EUV capability could take a decade or more, if it is achievable at all. The barriers are not only technical but also economic and logistical, as developing such systems requires a global network of suppliers and expertise that cannot be easily replicated. In the meantime, China’s reliance on DUV machines will likely continue, limiting its ability to produce chips at the most advanced nodes.
