ASML staff buy exclusive Lego replica of EUV lithography tool in numbers dwarfing actual machine sales
The exclusive set, available only to ASML personnel under a strict one-per-person rule, highlights the gap between the complexity of semiconductor engineering and public understanding.
The Netherlands-based semiconductor equipment maker ASML has seen its most coveted product shift from multi-million-dollar machinery to a plastic construction set. A 25,000-brick Lego replica of the company's Extreme Ultraviolet lithography tool has emerged as the firm's best-selling item, surpassing the sales of the actual industrial giants it mimics.
The project was initiated by Rick Lenssen, a data analyst at ASML, who combined his professional duties with a personal hobby of designing custom Lego sets. What began as a campus model evolved into a scaled-down representation of the world's most complex lithography machine, designed to help knowledge workers explain their high-stakes work to friends and family.
The exclusivity of the set mirrors the scarcity inherent in the semiconductor industry. The replica is sold strictly to ASML staff under a one-per-person rule and is not available for public purchase. In the same timeframe that only six actual EUV machines were sold to customers, 1,355 units of the Lego model were purchased by employees.
Each real EUV machine costs approximately $400 million, contains over 100,000 parts, and requires three Boeing 747 aircraft for delivery. The Lego set serves as a tangible bridge, allowing engineers to translate the abstract complexity of atomic-level precision into something accessible to non-specialists.
Secondary market listings for the exclusive sets have appeared on platforms such as eBay, reflecting the high demand among staff. Prices for these unofficial resales range from $600 for partial sets to $4,500 for full collections, further underscoring the value placed on the replica within the company.
While the actual machines remain the critical hardware powering iPhones, AI models, and data centres, the Lego replica has captured the imagination of the workforce. It stands as a testament to the desire to play even at the bleeding edge of human physics, turning a $400 million magic box into a toy that anyone can touch and build.
