Okmetic has entered volume production at its expanded Vantaa fab in Finland. The site focuses on 150–200 mm silicon and bonded silicon-on-insulator (SOI) wafers, with the expansion significantly increasing 200 mm polished wafer capacity.
“With this expansion, Okmetic strengthens its position as an EU-based, one-stop supplier for 150 to 200 mm silicon wafer platforms serving the MEMS, sensor, RF, and Power markets. The increase in 200 mm polished wafer capacity strengthens long-term supply stability for critical semiconductor applications,” said President and CEO Kai Seikku.
Okmetic produced the first wafers from the expanded fab in June 2025, launching a structured qualification and ramp phase. With volume production now underway in early 2026, the company has started delivering wafers from the expanded capacity to customers, supporting long-term supply readiness across MEMS, RF, Power and GaN-based applications.
The Vantaa expansion is part of Okmetic’s broader plan to more than double capacity by 2030. Construction began in early 2023 and adds more than 40,000 m², including a 6,000 m² cleanroom as well as new crystal growth and wafering areas. Okmetic said the fab upgrade incorporates state-of-the-art equipment with a focus on energy efficiency.
The latest investment builds on prior capacity additions, including the doubling of bonded SOI production capacity between 2017 and 2021 and the introduction of a patterning line for Cavity SOI (C-SOI®) production in 2019. By expanding 200 mm polished wafer output, Okmetic aims to better meet evolving industry demand while reinforcing Europe-based supply of 150–200 mm wafer platforms.
