South Korea launches ultra-innovation economy push with major investment in next-generation power semiconductors

South Korea’s aggressive push into next-gen power semiconductors is a strategic countermove to global decarbonization mandates and EV supply chain realignment. Technologically, this accelerates SiC/GaN adoption in 800V architectures, industrial converters, and solar inverters, forcing upstream upgrades in high-purity substrates and MOCVD/ion implantation tools. Regulatory risks loom large: heavy reliance on U.S.-Japan equipment and IP inflates operational costs and exposes supply chain fragility under tightening export controls. Competitively, Japan is doubling down on automotive module integration, while Taiwan, China leverages its foundry ecosystem to dominate mid-to-low voltage segments—leaving Korea’s IDM-centric approach vulnerable in diversified applications. Over the next 12–24 months, government incentives will spawn design startups, but lasting impact hinges on building a self-reliant compound semiconductor manufacturing cluster; otherwise, it’s just subsidy-fueled capacity bloat.
