ISC Breaks Ground on Songdo Fab, Targets Q1 2028 Opening

What happened

ISC said on Nov. 12 that it held a groundbreaking ceremony for its new fab in the Songdo Knowledge and Information Industrial Complex in Incheon, planning to invest about 35 billion won to consolidate its domestic production facilities (currently in Seongnam and Ansan) and core R&D operations at the single Songdo site, with construction scheduled for completion by 2027 and full operations set to begin in 2028. The project is part of a 100 billion won medium- to long-term investment plan announced in September, under which ISC will allocate 35 billion won each to its Songdo and Vietnam production sites, with the remaining 30 billion won used to introduce manufacturing AI and upgrade production and quality management systems at the two locations. The new fab will handle customized design of high-performance test sockets and initial mass production of new products, while Vietnam factories will handle mass production for global customers. ISC plans to expand its annual test socket production capacity in South Korea and overseas from 2 million units this year to 3 million in 2027, 4 million in 2028 and as many as 5 million in 2029. The expanded production line at its first Vietnam factory began full operations in October, and the second Vietnam factory is scheduled to begin mass production in the second quarter of next year.
