What SK Keyfoundry does
SK Keyfoundry is an 8-inch pure-play semiconductor foundry headquartered in Cheongju, South Korea, and a wholly-owned subsidiary of SK Hynix within the SK Group. The company provides analog and mixed-signal wafer foundry services to fabless and IDM customers globally, specializing in differentiated process technologies including BCD power (up to 200V), SOI BCD, Ultra High Voltage (700V), High Voltage IC (650V+), embedded Flash and other eNVM, Power Discrete, and — following its 2025 acquisition of SK Powertech — Silicon Carbide MOSFET processes spanning 450V to 2300V. Its process portfolio targets 0.35um to 0.13um nodes and is qualified to AEC-Q100 Grade 0/1 automotive standards, ISO 9001, IATF 16949, ISO/IEC 27001, and ANSI/ESD S20.20.
The company operates an enterprise go-to-market combining direct field sales through offices in Korea (Cheongju HQ and Seoul), the US (San Jose, also covering Europe), China (Shanghai and Shenzhen), Taiwan, and Japan, with a network of regional distributors and design-house partners (Pines, Synic Solution, MK Technology, Miracle International, Makoto Semiconductor, Gloryforever, SIMA Technology, Shinden Hightex, Woosung, Jiwave, GreenChips, Niti), the i-Foundry online customer portal for technical documents and order management, and a Multi-Project Wafer shuttle program with 2-month turnaround. Pricing is quote-based with multi-year contracts; revenue figures are not publicly disclosed.
SK Keyfoundry serves end-markets including automotive power management and motor drivers, industrial power conversion and motor control, consumer and IoT analog/mixed-signal ICs, and SiC power semiconductors for EV powertrains, renewable inverters, and high-voltage power supplies. The company traces its technology lineage to LG Semiconductor (1979), Hynix, and MagnaChip's foundry division, spun off in September 2020 as Keyfoundry, acquired by SK Hynix in August 2022, and rebranded SK Keyfoundry in January 2024.
