History.
The company was formed with parts of former semiconductor combine "Kombinat Mikroelektronik Erfurt", which had its headquarters and several production facilities in Erfurt.
As result of the German reunification came the dismantling of the old conglomerate and a partial privatization of the individual enterprises. The facilities in Erfurt were partially privatized in 1992 (part owned by " N.V." and Thuringia), including the "X-FAB Gesellschaft zur Fertigung von Wafern mbH" (manufacturing) and the "Thesys Gesellschaft für Mikroelektronik mbH" (design). In 1999, both enterprises were sold to the company "ELEX N.V." owned by Roland Duchâtelet, a Belgian investor.
In 2007, X-FAB acquired the foundry business from ZMD.
Until 2009, the X-FAB group also had a manufacturing facility in Plymouth, but the wafer plant in Plymouth, United Kingdom, was sold in December 2009 to Plus Semi, the old Plessey Semiconductors plant in Swindon, England.
In 2011, the X-FAB group acquired a share in MEMS Foundry Itzehoe GmbH which was a spin-off from Fraunhofer Institute for Silicon Technology (ISIT). This would become X-FAB's dedicated MEMS foundry in Itzehoe. 
In February 2011, the company announced that Rudi De Winter will be added to the Board of Directors as well as assume the role of co-CEO.
In 2016, the X-FAB group acquired the assets of , making the fab in France their sixth manufacturing site.
As of 2016 X-FAB has six plants, which are located in Germany (Erfurt, Dresden and Itzehoe), France (Corbeil-Essonnes), Malaysia (Kuching) and in the United States (Lubbock). The group employs about 3,800 workers, and in 2013 had sales of USD 290 million. Its CEO is Rudi De Winter.
