RootSemicon Selected to Lead Domestic 3300V SiC Module Development Project - thelec.net

RootSemicon has been selected as the lead organization for a South Korean government-backed project to develop domestically produced 3300-volt silicon carbide (SiC) power modules. The initiative, supe... Read original →

South Korea’s push for a domestic 3300V SiC module isn’t just about voltage—it’s a strategic bypass of supply chokepoints dominated by Infineon and Mitsubishi Electric. With current local capabilities capped at 1700V, this KEIT-backed initiative forces vertical integration: Arke must refine epitaxial uniformity, SemiPowerEx advance high-temperature packaging, and Intec validate real-world reliability. Policy linkage reduces upfront R&D risk but risks technological rigidity if the project locks into a narrow voltage spec. Competitively, Infineon may counter with localized JVs in Korea, while Taiwan, China’s power semiconductor players—still clustered below 1200V—face exclusion from next-gen rail and grid markets. Within 18 months, successful yield ramping could let Korean firms set regional standards in solid-state circuit breakers and EV fast-charging, positioning them as preferred partners for ASEAN grid modernization.
