What SemiHow does
SemiHow Co., Ltd. is a South Korean fabless power semiconductor company founded in 2002 and headquartered in Gyeonggi-do, designing and selling a comprehensive portfolio of more than 900 power discrete products — including Super Junction MOSFETs, LV Trench MOSFETs, Planar MOSFETs, SiC MOSFETs, GaN FETs, IGBTs (with Trench Field Stop technology), TRIACs/SCRs, BJTs, Si/SiC diodes, and integrated IGBT and MOSFET power modules. All devices are manufactured through a strategic partnership with Samsung Foundry on 8-inch wafer process technology, positioning SemiHow as Samsung Foundry's named strategic product line for power discretes. The company developed Korea's first Epi-Stack based Super Junction MOSFET and has secured AEC-Q101 automotive qualification across multiple IGBT and MOSFET product families, enabling entry into tier-1 automotive platforms.
SemiHow generates revenue through B2B hardware sales of power semiconductor components to enterprise customers across three primary verticals: automotive (Hyundai, KIA, Doosan Bobcat, Volvo — principally EV/EREV PTC heater IGBTs), consumer electronics (Samsung Electronics across multiple divisions, LG, Coway, Cuckoo, Bodyfriend, Google, OPPO, VIVO, HP, Yamaha, SK magic, Hanil Electric — covering chargers, appliances, audio, and personal care), and industrial (KEPCO, Korea Expressway Corporation, Japan Toyostar — covering SMPS, UPS, and LED lighting). Go-to-market is sales-led via direct enterprise engagement, regional sales offices (including a 2024 expansion in Northern India), trade exhibitions such as SEDEX and Electronica India, and technical documentation including product catalogs and an online cross-reference tool that maps competitor part numbers to SemiHow equivalents. Pricing is quote-based and not publicly disclosed.
In July 2025, SemiHow submitted a preliminary listing application for KOSDAQ via a SPAC merger with Daishin Balance No.16 SPAC, with Daishin Securities as lead underwriter. The company has received the 2022 $10M Export Tower Award from the Korea International Trade Association, the 2021 Venture of the Year Award from the Minister of SMEs and Startups, and 2024 BIRD Program government grants supporting export-oriented R&D, signaling a deliberate scaling trajectory from a sub-50-employee private firm toward a publicly listed Korean power semiconductor franchise.
