VELDHOVEN, the Netherlands, 22 April 2015 - ASML Holding NV (ASML) today announces that it has signed an agreement with one of its major US customers to deliver a minimum of 15 ASML EUV lithography systems to support increased development activity and pilot production of future-generation manufacturing processes. The customer intends to use EUV lithography for multiple processing steps in future process technology nodes. The delivery of the first two NXE:3350B EUV systems is expected before the end of 2015. The new systems will be in addition to the existing EUV development systems already at the customer. Financial terms were not disclosed.

Extreme Ultraviolet (EUV) lithography is the leading new patterning technology that simplifies the manufacturing process for the most advanced chips with significant benefits in terms of yield and cycle time. It will help the semiconductor industry to continue Moore's Law well into the next decade by packing more transistors on a chip, reducing cost-per-function and improving energy efficiency.

"EUV is now approaching volume introduction. Long-term EUV planning and EUV ecosystem preparation is greatly supported by this commitment to EUV, kick-starting a new round of innovation in the semiconductor industry. The commitment extends the planning horizon and increases the confidence in EUV," ASML President and Chief Executive Officer Peter Wennink said.

About EUV
Lithography is an optical technology that is used to image the circuits on a chip. One of the key factors that determine the resolution that can be achieved with lithography is the wavelength of the light. Extreme Ultraviolet (EUV) Lithography uses light of a shorter wavelength (13.5 nanometers) than the current standard in volume production of the most advanced chips, immersion lithography (193 nanometers). EUV can thus image smaller features without the need for multiple exposures, and allows semiconductor device makers to simplify the manufacturing process, exposing a critical layer of a chip in a single step.
