ASML’s chipmaking business extends far beyond selling a new machine

About 29.6% of ASML’s reported second-quarter 2026 sales came from Installed Base Management: service and field options, including upgrades. The ratio—€2.762 billion divided by €9.326 billion—makes a useful starting point for understanding the company. ASML supplies the lithography machines used to make chips, then helps customers keep those machines productive.[4][1]

A machine that prints with light

Extreme ultraviolet, or EUV, lithography uses light with a wavelength of 13.5 nanometres. ASML describes generating that light by striking tiny tin droplets with powerful laser pulses. The beam then travels through an optical system to project the pattern. EUV is absorbed readily enough that the light path needs a vacuum and specialised mirrors rather than the ordinary lenses a reader might imagine from a camera.[2]

The product families also differ in numerical aperture, a property of the projection optics relevant to resolution. ASML distinguishes its NXE systems at 0.33 from the higher-aperture EXE platform at 0.55. This is a change in how a pattern can be imaged, not a claim that buying one machine automatically produces a finished chip. The exposure system is a component in a much larger manufacturing process.[2]

Why older equipment does not simply disappear

ASML’s deep-ultraviolet portfolio includes immersion and dry systems. Chip layers do not all require the same patterning capability, so a manufacturer can use different equipment for different jobs. The company explicitly describes less demanding layers being produced with older dry technology because it can cost less to acquire and maintain. Advanced manufacturing therefore does not mean replacing every exposure step with the most expensive available option.[3]

Upgrades matter too. ASML offers enhancement packages for its NXT immersion platform, allowing customers to improve an installed system rather than always buying another complete machine. The commercial question is consequently broader than “Which generation is newest?” A manufacturer must consider the layer, required performance, existing equipment and the value of an upgrade in that particular production line.[3]

Keeping a fabrication plant working

ASML describes support as a continuing operational relationship: anticipating maintenance, planning work with the customer and making spare parts available close to the machines. Applications specialists also help monitor and improve performance. A scheduled intervention and an unexpected stoppage may involve similar physical work but have very different consequences for the customer’s production plan.[5]

Even moving a system is a service. Relocation requires preparation, materials, installation engineers and sometimes refurbishment. The equipment’s business life can therefore involve its original sale, years of support, upgrades and a later move. The supplier’s relationship with a fabrication plant does not end when a crate arrives at the loading bay.[5]

A second life can be a first-class product

The PAS 5500 platform was introduced in 1991, yet ASML still describes applications for refurbished systems in areas such as sensors, microelectromechanical systems and photonics. Its Linkou process involves dismantling equipment into modules, repairing and testing them, and rebuilding the system to specified requirements. Refurbished machines receive a new warranty; options can adapt them to a new customer’s job.[6]

That is different from selling a used machine unchanged. The engineering and support promise are part of what the buyer acquires. ASML also identifies continuing support for the PAS 5500 family through 2035 and beyond. This is the supplier’s stated commitment, not a guarantee that any particular customer will operate a machine for that entire period.[6]

The purchasing decision behind the technology

Consider a fictional manufacturer deciding between upgrading an installed tool and buying another one. The purchase price alone cannot settle the choice. The useful comparison would include additional output, installation time, available floor space, training, maintenance and whether the new capacity matches the actual production bottleneck. A faster exposure stage has little value if another stage already determines how many completed wafers can leave the line.

The example is fictional, not a customer quotation. It shows why service, upgrades and second-life systems belong in the same business story as the most advanced optics: the customer buys usable manufacturing capability over the machine’s working life.
