Okmetic manufactures 150mm-200mm silicon wafers for microelectromechanical (MEMS) systems, sensors, RF, and power devices. Their portfolio includes Silicon On Insulator wafers, patterned wafers, and single and double side polished wafers.

The majority of their production capacity is located in Vantaa, Finland. However, their 'Fab lite' model involves partnering with Asian subcontractors to secure enough production capacity at peak demand.
