Production and capacity expansion 

Okmetic headquarters and production site located in Finland focus on crystal growing and 150 to 200 mm silicon wafers. The fab expansion under construction will focus on 200 mm wafers and more than double Okmetic capacity. We also uses long-term subcontracting partners in Asia.

Okmetic Vantaa site in Finland focuses on crystal growing and production of 150 to 200 mm wafers silicon wafers for the MEMS, RF and Power device markets. The Vantaa site produces SSP, DSP and Bonded SOI wafers with and without cavities optimized for different device needs. Our decades long expertise in crystal growth, wafering, and Silicon-On-Insulators as well as in-house capabilities for lithographic patterning and deep reactive-ion etching guarantee the optimal platform for the manufacture of even the most advanced of devices. High quality and sustainability are an integral part of Okmetic production and operations.

Fab expansion adding 200 mm wafer capacity significantly 

Okmetic is currently building a fab expansion, that will more than double Okmetic Vantaa site capacity. The fab expansion will be in operation in 2025 and focus on 200 mm crystal growth as well as 200 mm SSP and DSP wafers.

Fab lite model secures enough capacity

In addition to own production capacity, Okmetic also uses long-term subcontracting partners in Asia to support its customers in varying market and demand situations. This so-called fab-lite model has been part of Okmetic production strategy since 2004. It adds flexibility to operations and enables Okmetic to offer additional SSP capacity for varying market and demand situations. In this model, all crystals are grown in Vantaa but 150-200 mm SSP wafering is outsourced. 

Okmetic uses long-term subcontracting partners to offer additional capacity for customers in dynamic market and demand situations

Similarly to the products that are produced entirely at the Vantaa plant, Okmetic offers full support for subcontracted wafers. Okmetic is in charge of the whole process including partnership, project and quality management, customer technical support as well as order and delivery. Okmetic guarantees the quality of the outsourced wafers and services. Okmetic has long-term contracts with all of its fab-lite partners. The partners have been tested thoroughly and are audited regularly. Our fab-lite partners hold all relevant quality and environmental certificates.
