Centre for III-nitride technology (C3NiT)

Next Generation Power and High Frequency Electronics.

The Centre for III-nitride technology (C3NiT) – a Vinnova Competence Centre – aims to establish a platform for generating and exploiting cutting-edge research in III-nitride semiconductors for the next generation of power and high frequency electronics, through a combination of scientific excellence and industrial relevance.

C3NiT is funded in equal parts by VINNOVA, industry and academic partners.

C3NiT consists of the academic partners Linköping University and Chalmers University of Technology, together with the industrial partners ABB, Ericsson, Epiluvac, Gotmic, Norstel, ON Semiconductor, SAAB, SweGaN and United Monolithic Semiconductors, and the Swedish Defence Materiel Administration (FMV). This group of partners covers the whole supply chain, from material growth to usage of devices and circuits at the system level, which is quite unique even for larger research programs.

C3NiT is the first collective effort on III-nitride power electronics in Sweden, where both industry and academia work together to solve technological issues in the field relevant to Swedish industrial competitiveness.


III-nitride semiconductors have proven to be extremely suitable for both high frequency electronics as well as power electronics, where a combination of high power generation, amplification, and switching is required.

Sweden has several important industries that rely on advanced semiconductor technologies in their systems. Most notably, within the high frequency electronics area, Ericsson is a major player in wireless communication, Saab is in the forefront of the defense industry and sensing applications (i.e. radar), and within power electronics, ABB is a major supplier of power infrastructure.

Through C3NiT, industrial partners work together with academia to investigate, explore, and solve challenges, as well as push the boundaries of III-N electronics.

C3NiT aims at performing collaborative research and enhance utilization of research results, generating innovation in high-frequency and power electronics based on III-Ns, addressing the global and societal challenges on greenhouse gas emissions and the increasing dependence on mobile data. The industrial exploitation of the results generated within the centre is mainly secured by active participation of the company partners.

The centre builds on previously existing collaborations between several of the partners in C3NiT, where research have been performed both on a fundamental level, as well as on more applied research with industrial partners and public agencies for the past two decades. C3NiT facilitates and supports a continuous growth of this established Swedish cluster, and strengthens already existing international collaborations, which are of importance for Swedish industrial competiveness.


The overall mission is to perform and transfer research results on III-N high frequency and high power technology directly exploitable by industrial partners at different levels in the supply chain.


The vision of the centre is to further stimulate and boost the Swedish Industry-Academia Cluster on group III-nitrides and to elevate its position and become the leading wide bandgap cluster in the world.


Short-term (1-5 years)

  • We have developed and strengthened the cluster in terms of more efficient collaboration and by attracting new industrial partners.
  • We have used the existing innovation systems at LiU and Chalmers to accelerate knowledge transfer to the industrial partners.
  • We have defined new areas where III-N electronics can be utilized and initiated activities in these areas.
  • We have initiated new research activities motivated by requirements posed by industrial collaboration (e.g. reliability)
  • We have promoted the mobility between industry and academia by encouraging and supporting long term stays, guest lecturing, supervision etc.
  • We have developed the research infrastructures (for material growth and characterization; device and circuit fabrication and characterization) at academia to be able to support relevant industrial collaborations.
  • We have, through the research programs in the centre, been able to initiate and attract new international academic collaboration partners.

Long-term (10 years)

  • We have performed research that is relevant and directly transferable to industrial partners at different levels in the supply chain, which is evidenced by IP (patents and licenses), standardization, new products, growing SMEs, and new spin-offs.
  • We have educated researchers and engineers with relevant knowledge and experience, as evidenced by PhDs employed by the industrial partners. These persons will have the capability of utilizing research results in an industrial environment. In this way they can secure an efficient method of knowledge transfer and will promote further collaborations between academia and industry.
  • The collaborative research has contributed to new research areas which have attracted funding to academia.
  • We have contributed to the availability of III-N electronics for the industrial partners by supporting the growth of a Swedish and European supply-chain.
  • We have initiated and followed cutting edge research in III-N based electronics as evidenced by publications and invited talks.
