Okmetic has successfully produced the first wafers from its new Vantaa fab expansion in Finland. 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.
The completion of the first phase of what will ultimately be 400 million euro expansion, the largest investment in company history, is a significant milestone coinciding with Okmetic’s 40th anniversary. With the first wafers successfully produced, the company is now preparing for sample deliveries to customers, marking the next step in ramping up production.
Vantaa site Fab expansion is set to more than double Okmetic capacity by 2030. The construction of the expansion began in early 2023. Spanning over 40,000 m², the expansion includes a 6,000 m² cleanroom area along with crystal growth and wafering areas. The fab expansion is equipped with state-of-the-art technology, with focus on energy efficiency.
Building on previous investments, Okmetic has significantly expanded its manufacturing capabilities in recent years, including doubling bonded SOI production capacity between 2017 and 2021 and adding a patterning line for Cavity SOI (C-SOI®) production in 2019.
This latest expansion further strengthens Okmetic’s ability to meet growing semiconductor industry demands. By significantly increasing 200 mm polished wafer capacity, it reinforces Okmetic’s position as a leading supplier of advanced silicon wafers based in Europe, ensuring a stable and high-quality supply of 150–200 mm wafers.
