By the 1990s, consortiums like ASML, along with research partners, began dedicated development efforts to overcome the fundamental challenges of creating viable EUV systems.

The technological progression accelerated in the early 2000s with the development of prototype EUV light sources and reflective optics systems. A critical milestone occurred in 2006 when ASML demonstrated the first full-field EUV lithography scanner. However, it wasn't until 2018 that EUV technology achieved commercial viability with ASML's TWINSCAN NXE:3400B system, capable of high-volume manufacturing at the 7nm node.

EUV lithography operates at a wavelength of 13.5nm, significantly shorter than the 193nm used in DUV systems. This dramatic reduction enables the printing of much finer features, addressing the limitations of traditional optical lithography techniques that had reached their physical boundaries. The technology employs a fundamentally different approach, using reflective rather than refractive optics and requiring vacuum environments due to EUV light's absorption by air molecules.

The primary objective of EUV lithography development has been to enable continued semiconductor scaling according to Moore's Law, which had faced increasing challenges with conventional lithography methods. Specific technical goals include achieving resolution capabilities below 10nm, improving throughput to economically viable levels (currently targeting >125 wafers per hour), enhancing overlay accuracy to <2nm, and reducing defectivity to levels acceptable for high-volume manufacturing.

Looking forward, the industry aims to extend EUV technology through several generations, with high-NA (numerical aperture) EUV systems representing the next major advancement. These systems promise to further improve resolution capabilities to support 3nm nodes and beyond. Additional objectives include reducing the total cost of ownership, improving source power and reliability, and developing complementary technologies such as advanced resists and mask infrastructure.
