NORSTEL

Norstel AB (www.norstel.com) was established in 2005 as a spin-off from Linköping University and the Finnish silicon wafer manufacturer Okmetic Oyj. Today Norstel is an SME employing 45 people and operating its own purpose-built 2000 m2 plant in Norrköping, Sweden, focusing on developing and manufacturing single crystal SiC materials for electronic device applications. The product range includes conductive and semi-insulating SiC substrates as well as custom-made epitaxial structures covering a wide variety of doping and thickness. Norstel’s customer base includes well known power device companies in Europe, Asia and the USA.

A proprietary technology for crystal growth, HTCVD, is the basis for Norstel’s semi-insulating products. By growing the material directly from gases very pure crystals with well controlled properties can be grown. Combining its pioneering role in developing HTCVD growth with expertise in SiC materials Norstel has secured key process and product patents related to the manufacturing of semi-insulating and low-doped SiC.
