Investments support future growth
Okmetic’s most recent investment in a fab expansion is the largest in the company history. The investments amounts to almost 400 MEUR and it will more than double production capacity and business.
Fab expansion on Vantaa site in Finland
In May 2022, we announced the largest investment in the company history, almost 400 million euro, to construct a fab expansion in Vantaa, Finland. The fab expansion was completed in early 2025 and the first silicon wafers were produced in June 2025.
Okmetic Vantaa site caters all 150 and 200 mm silicon wafer needs.
Okmetic Vantaa fab focuses on 150-200 mm silicon and bonded silicon-on-insulator (SOI) wafers with large fab expansion adding 200 mm polished wafer capacity significantly.
Covering over 40,000 m², the new fab expansion includes approximately 6,000 m² of cleanroom space, along with dedicated crystal growth and wafering areas. Built as an extension to the existing fab, the expansion maximizes operational synergy across the site. The original facility continues to focus on 150–200 mm polished and bonded SOI wafer production, as well as crystal growth, complementing the expanded 200 mm polished wafer and crystal growth capabilities of the fab expansion.
Okmetic’s expansion positions the company as an EU-based, one-stop supplier for 150–200 mm silicon wafers across MEMS, RF, and Power markets, strengthening its role and ensuring increased 200 mm polished wafer capacity to support high-quality, stable supply for critical semiconductor applications.
Become part of our growth story
The investment will create more than 500 new jobs. We will be hiring professionals for both white-collar and production positions.
Previous investments
Okmetic’s production capacity has been increased over the years by investing in both fab expansions as well as on equipment and processes. The existing fab has been expanded several times: more office space, crystal growth and clean room space for SOI production have been built.
Between 2017 and 2021, Okmetic invested over 100 MEUR for the Vantaa plant to increase production capacity of high value-added 200mm wafers, SOI wafers, Patterned wafers and High Resistivity RFSi® wafers.
