South Korea just made what might be the single largest regional development bet in semiconductor history. President Lee Jae Myung announced plans to build a massive chip production cluster in the country’s southwestern region, backed by 800 trillion won, roughly $518 billion, from Samsung Electronics and SK Hynix.
The plan, unveiled on June 29 at the Blue House with key industry leaders present, calls for four new semiconductor fabrication plants split evenly between the two Korean chip giants. The target location: Gwangju city and South Jeolla province, an area that has historically been underdeveloped compared to the booming Seoul metropolitan corridor.
The AI chip arms race gets a new battlefield
The initiative is part of a broader $576 billion AI-chip drive, designed to meet the surging global demand for high-bandwidth memory chips that power artificial intelligence workloads. Samsung and SK Hynix already control around two-thirds of the world’s memory chip supply.
The Seoul metro area, where most of South Korea’s chip production is currently concentrated, is running into infrastructure constraints. Power grids, water supply, land availability: all of the physical resources that semiconductor fabs devour in enormous quantities are getting strained in the capital region. The southwestern region offers space, renewable energy resources, and room to build without competing against residential and commercial development for every acre.
