What Phenitec does

Phenitec Semiconductor Corporation (フェニテックセミコンダクター株式会社) is a Japan-based independent wafer foundry and discrete semiconductor manufacturer founded in October 1968 (originally as Shinko Denki Corporation, renamed in 1998) and headquartered in Ibara City, Okayama Prefecture. The company operates three production sites — Okayama Plant 1 (headquarters, 5-inch and 6-inch lines), Okayama Plant 2 (compound semiconductor prototyping for Ga2O3 and GaAs), and Kagoshima Factory (6-inch, acquired from Yamaha Kagoshima Semiconductor in 2015) — supported by group company Seibitec Corporation for dicing and wafer testing. Phenitec holds ISO 9001, IATF 16949 (automotive, at both Okayama and Kagoshima), ISO 14001, and ISO 45001 certifications, and employs 694 people.

The company runs two business lines. The Foundry (OEM) line provides integrated custom manufacturing from epitaxial growth through wafer processing, inspection, and testing on 5-inch and 6-inch lines in Japan, including a CMOS Shuttle Service that shares reticle space for cost-effective multi-project prototyping. The In-house Development line sells proprietary discrete semiconductors — N-channel and P-channel MOSFETs, NPN/PNP bipolar transistors, Zener, Schottky, switching diodes, built-in resistor transistors (BRT), and TVS — alongside a growing silicon carbide (SiC) portfolio spanning SiC SBDs (650V to 1200V across Generation III and IV) and SiC MOSFETs (planar, 1200V to 3000V, with trench under development). Phenitec also participates in the Tsukuba Power Electronics Constellations (TPEC) program under AIST for advanced SiC device research.

Phenitec generates revenue through direct B2B sales of catalog semiconductor products, custom foundry contracts, and emerging SiC device sales targeting automotive, industrial, and renewable energy power conversion applications. Go-to-market is sales-led, conducted through the Headquarters Sales Department in Ibara and the Kyoto Sales Office, with customer acquisition driven by the company website, product inquiry forms, and direct enterprise outreach. The company maintains a capital and business alliance with Torex Semiconductor Co., Ltd. (a strategic operating-company relationship since 2016) and reports global participation in the SiC Epitaxy Services market across North America and Asia-Pacific. Revenue figures are not publicly disclosed.
