Dr. Meri Helle is the Executive Chairwoman and founder of OneFab Nordic Oy.

OneFab Nordic is a Finnish microelectronics manufacturing and technology integration company founded in January 2025 in Helsinki, Finland, focusing on a compound semiconductor material aluminum nitride.

With a team of 13 industry experts, nine team members and a four-member advisory board. Three professors, nine doctors in science and technology and four MSc’s, OneFab has over 450 years of cumulated experience in the field of semiconductor industry, microelectronics, photonics, physics, wireless and optical communications, etc.

Dr. Helle started her entrepreneurial career in 2015 by co-founding Summa Semiconductor Oy, a specialty foundry and R&D service company that operated in Micronova cleanrooms in Finland. Ms. Helle was also the CEO of joint-venture foundry company OneFab Finland Oy, ”a OneFab First”, from 2018 to 2023.

OneFab Finland prepared a business and investment plan of €100 million for building a new manufacturing facility with novel business model offering specialty manufacturing processes for microelectronics and photonics. OneFab’s foundry services were targeted for industrial pre-volumes and medium manufacturing volumes, between R&D institutes and large foundries, i.e. helping customers to ramp-up industrial production.

Before jumping into the entrepreneurial path, Dr. Helle worked for silicon wafer manufacturing company Okmetic. At Okmetic she held a Process Engineer position (2011-2012) at Okmetic’s silicon wafer manufacturing fab in Finland and 2012-2015 a Technical Customer Support Engineer position at Okmetic’s sales team with main responsibilities in Taiwan, Singapore and Malaysia. Prior joining Okmetic, Dr. Helle was also part of Nokia Research Center’s graphene research team (2010-2011).

After finishing MSc (2001) and Doctoral (2006) in quantum physics in Aalto University, Ms. Helle continued her academic career in Low Temperature Laboratory, Aalto University as Academy of Finland Post-Doctoral Researcher Scientist (2006-2010). Her research consisted of superconducting nanoelectronics device fabrication in the Micronova cleanrooms and cryogenic-temperature measurements of quantum phenomena of superconducting
nano-devices.
