AI demand lifts the Korean chip industry

The AI boom has placed Korean semiconductor firms at the center of global supply chains, particularly in high-bandwidth memory (HBM), where SK hynix and Samsung Electronics supply leading AI accelerator makers. Investment commitments across the industry have reached the thousands-of-trillions-of-won scale cited in the claim.

The scale of spending reflects both private capex — fab construction, HBM lines and foundry expansion — and policy support, with the Ministry of Science and ICT among the government bodies backing the sector's growth.

Context and caveats

The headline figure aggregates investment across many years, companies and projects rather than a single outlay, so the total should be read as a cumulative, multi-actor sum. Specific allocations by company or program were not detailed in the material reviewed.

With that framing in mind, the claim that thousands of trillions of won are flowing into K-semiconductors is largely accurate in scale, direction and industry context, making the overall assessment Mostly True.
