Trinity Fab, Built on SK hynix’s Production Expertise, to Open Next October

What happened

According to industry sources on Nov. 6, Trinity Fab, a nonprofit foundation jointly established by the South Korean government, Gyeonggi Province, Yongin City and SK hynix, plans to open its cleanroom in May 2027 and begin full-scale testbed operations in October. The facility will provide a 300mm wafer-based validation environment similar to SK hynix's front-end semiconductor production lines, aiming to support technology development and product commercialization by domestic semiconductor materials, components and equipment suppliers, address bottlenecks preventing them from entering mass production, and localize technologies currently dependent on overseas sources. Trinity Fab plans to begin installing equipment in May and launch validation services in October, introducing 37 pieces of equipment with 70% scheduled for installation by October and the remainder phased in through 2031. SK hynix is contributing 443.2 billion won toward construction, the central government 373.6 billion won, and Gyeonggi Province and Yongin City 57.7 billion won; equipment investment will total approximately 300 billion won, with the most expensive system being an argon fluoride (ArF) immersion lithography machine from ASML, and etching validation using equipment from Lam Research, Applied Materials (AMAT) and Hitachi. The facility will be located within Phase 1 of SK hynix's initial fabrication plant at the Yongin Semiconductor Cluster, occupying approximately 1,000 pyeong (3,306 square meters) of a roughly 12,000-pyeong area, with a cleanroom of Class 100 or better; 800 pyeong will be divided into seven process areas (diffusion, lithography, etching, thin-film deposition, CMP, cleaning, and metrology and inspection), while the remaining 200 pyeong will be a shared cleanroom divided into 15 units of approximately 13.5 pyeong each for suppliers' own equipment. The facility aims to reduce the time for domestic suppliers to move from development to mass-production adoption by 30% and plans to support approximately 300 companies. Recruitment for the shared cleanroom is under way, with tenants to be selected following an internal review in January 2027; selected tenants will be able to install their own equipment starting in the second half of 2027. Trinity Fab is targeting annual revenue of at least 30 billion won, and after infrastructure construction is completed in 2031, including government-funded investments, the foundation aims to continue operating and upgrading equipment using internally generated revenue.
