Samsung plans to introduce High-NA EUV technology with 1-nanometer process by 2030
Park Chang-min from Samsung Electronics Semiconductor Research Institute's Foundry Process Development Team stated at the "2026 Next Generation Lithography + Patterning Academic Conference" that the company plans to apply High-NA EUV technology starting from the 1-nanometer (A10) process, aiming for mass production around 2030. Samsung is currently still using the existing 0.33 NA EUV multiple patterning scheme for processes at 2 nanometers and below, with plans to achieve mass production of 1.4 nanometers by 2029, and then advance to 1 nanometer.High-NA EUV will increase the lens numerical aperture (NA) from 0.33 to 0.55, providing higher resolution, which can simplify ultra-fine processes that originally required multiple patterning into single patterning, helping to reduce manufacturing costs, improve production efficiency, and enhance design flexibility. However, this technology is highly challenging, equipment is expensive, and it requires simultaneous upgrades in supporting material technologies. Park Chang-min expects that the 1.4 nanometer and 1 nanometer processes will still primarily use 0.33 NA EUV multiple patterning, after which High-NA patterning will become the core technology of the new generation processes.
