ASML appoints veteran Marco Pieters as new chief technology officer

ASML, the world’s leading manufacturer of semiconductor lithography machines, has named Marco Pieters as its new chief technology officer (CTO), the company announced Thursday. Pieters, a 25-year ASML veteran, will also join the firm’s management board, pending approval at the April 2026 annual meeting.

Trained as a mathematician, Pieters has led several of ASML’s major product lines, including its Holistic Lithography program, which integrates hardware and software to improve chipmaking precision. CEO Christophe Fouquet praised Pieters’ long-standing contributions, saying he has “full support in driving forward our technology roadmap.”

Pieters succeeds Martin van der Brink, who retired in 2024 after a four-decade career that saw ASML rise from a small Dutch equipment supplier to a global leader in chip manufacturing technology. Van der Brink’s strategic bets on extreme ultraviolet (EUV) lithography helped ASML overtake rivals Nikon and Canon to dominate the sector.

ASML’s advanced lithography machines — some priced at $400 million — are essential to producing cutting-edge chips used in AI processors, smartphones, and data centers. Pieters’ appointment reinforces ASML’s focus on innovation amid rising global demand for semiconductor technology.

The company also plans to reappoint CFO Roger Dassen at the same meeting.

ASML CEO Discusses Positive Impact of DeepSeek AI Launch on Chip Demand

Christophe Fouquet, CEO of ASML, shared his perspective on the growing influence of AI technologies, such as China’s DeepSeek, on the global chip market. He emphasized that efficient AI models are ultimately a positive force for the semiconductor industry, countering the perception that AI spending is primarily driven by large-scale investments from tech giants like Google, Meta, and Microsoft. These companies are pouring billions into building advanced data centers, but according to Fouquet, the actual demand for chips driven by this sector remains relatively small.

Fouquet argued that the broader chip demand will come from the integration of AI into various consumer and industrial applications. He highlighted examples, such as AI-enabled phones, cars, and robotics, noting that for these products to reach mass adoption, the cost of the chips must be affordable. If the cost of chips remains high, only a small number of expensive units would be sold, limiting widespread access to AI technology.

When discussing the recent launch of DeepSeek’s AI product, which had a significant impact on tech stock prices, Fouquet remained optimistic, stating that anything that helps drive down costs is beneficial for ASML in the long run. While the potential of DeepSeek’s technology remains uncertain, he believes that cost reduction is key to enabling AI to be more accessible to a wider audience.

Analyst Sara Russo from Bernstein agreed with Fouquet’s viewpoint but noted that the effects of DeepSeek’s launch are still unfolding. She pointed out that ASML’s role as a supplier will depend on how AI applications evolve and influence chip demand, as well as the needs of chip manufacturers.
