Siltronic AG is a German manufacturer of wafers made of hyperpure silicon headquartered in Munich.
History
In 1953, it all began in Burghausen Germany as Wacker Chemie was already researching and developing hyperpure silicon, which lead to the first semiconductor silicon to be produced in 1958. The number of employees were increased in 1961 as they began to add products, such as monocrystals, which were also distributed internationally. In 1965, Wacker acquired Monosilicon, a silicon producer in Los Angeles, USA.[2][3]
The new wholly owned subsidiary company was founded in 1968 as Wacker-Chemitronic Gesellschaft für Elektronik-Grundstoffe mbH ("Wacker-Chemitronic") in Burghausen. In 1978, Wacker-Chemic built a plant in Portland, Oregon and founded the Wacker Siltronic Corporation. Workers were trained in Germany before the plants opening in 1980. In 1985, a joint venture for the production of 125 mm and 150 mm wafers began in Japan with NSC Electron Corporation.[2] It changed its name to Wacker Siltronic GmbH in 1994.
