SiCrystal @ http://www.sicrystal.de/content/DE/start.html

Europe's largest SiC single crystalline wafer maker.
SiCrystals roots date back to 1994, when a successful federally funded project on crystal growth of silicon carbide bulk crystals was launched. Subsequently, the company was formed in 1996. The first wafers were commercially available in 1997. From that time on a rapid development took place. After the merger with the Siemens-owned SiC-supplier Freitronics Wafer GmbH & Co.
KG in spring 2000, the stock-company SiCrystal AG is located in N?rnberg in the northern part of Bavaria, Germany.
Last important step was the successive take-over of the shares by ROHM, which was completed in 2010.

CrystAl-N was founded in 2010 as a spin-off from the Materials Science Department 6 of Friedrich-Alexander-University Erlangen-Nuremberg (Germany) with more than 10 years of expertise in the growth of bulk AlN crystals. The Company is led by the renowned crystal growth expert Dr. Boris Epelbaum and Dr. Paul Heimann. CrystAl-N is advised by senior scientist Prof. Albrecht Winnacker and serial entrepreneur Horst Linn who previously founded SiCrystal AG. In 2013, the CrystAl-N product portfolio was enlarged by offering ultrapure aluminum nitride powder and tungsten and molybdenum parts.
