Siltronic

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.{{Cite web |title=Siltronic AG {{!}} Encyclopedia.com |url=https://www.encyclopedia.com/books/politics-and-business-magazines/siltronic-ag |access-date=2024-01-03 |website=www.encyclopedia.com}}{{Cite web |title=Historic Overview Of Silicon Crystal Pulling Development |url=https://www.tf.uni-kiel.de/matwis/amat/elmat_en/articles/historic_review_cryst_growt.pdf |access-date=2024-01-03}}

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. It changed its name to Wacker Siltronic GmbH in 1994. They then acquired the hyperpure silicon plant located in Freiberg, Germany in 1995, where the VEB Spurenmetalle Freiberg was integrated into Wacker Siltronic after the building was modernized. Initially 150 mm wafers were produced there, then later on the production of 200 mm wafers began.{{Cite web |title=Wacker Siltronic AG in Saxony |url=https://tu-dresden.de/ressourcen/dateien/forschung/wissens-_und_technologietransfer/dresdner_transferbrief/archivordner/dtb02_00/Ausgabe_02_00_komplett.pdf?lang=de |access-date=2024-01-13}} The company was renamed as a stock corporation (Wacker Siltronic AG) in 1996.
