Siltronic

The company was founded in 1968 as Wacker-Chemitronic Gesellschaft für Elektronik-Grundstoffe mbH in Burghausen and changed its name to Wacker Siltronic GmbH in 1994. The company was renamed as a stock corporation in 1996. In 2004, the company changed its name to Siltronic AG.

The company manufactures silicon wafers with diameters of up to 300 mm at its two German production sites in Burghausen and Freiberg, as well as at sites in Asia and the USA. The company is a member of the Silicon Saxony association/industry association.

In 2020, it was announced that Siltronic would be sold to Taiwanese manufacturer GlobalWafers, a subsidiary of Sino-American Silicon Products , for a good 3.7 billion euros. The offer was increased to around 4.4 billion euros in 2021. According to the two companies, the merger would create a leading supplier to the wafer industry with a comprehensive product portfolio and the ability to offer technologically advanced products to all semiconductor customers. Siltronic AG is in advanced discussions, nearing completion, regarding a takeover offer from GlobalWafers. But the deal did not receive regulatory approval on time. GlobalWafers already acquired SunEdison's semiconductor business in 2016.
