SK Siltron

SK Siltron is a South Korean manufacturer of silicon wafers for the semiconductor industry. The supplied company description identifies it as a subsidiary of SK Group and places its headquarters in Gumi, South Korea. Its history traces to a business founded in 1983 under the name Dongbu Electronic and Communications Co.; it became Siltron in 1990 after an acquisition by Lucky Advanced Materials Inc. The company adopted the name SK Siltron Inc. in 2017 following SK’s acquisition of a majority stake. The company manufactures wafers in Gumi and Incheon. Its product range includes polished and epitaxial wafers with diameters from 150 mm to 450 mm, as well as solar wafers. The supplied source describes SK Siltron as the fourth-largest manufacturer of 300 mm wafers. These products place the company in the semiconductor-materials segment, supplying wafer substrates used in chip manufacturing. The available evidence does not identify specific customer markets, named product lines, current executives, or a detailed geographic breakdown of sales.

SK Siltron’s corporate history begins in 1983, when the business was established as Dongbu Electronic and Communications Co. In 1990, after being acquired by Lucky Advanced Materials Inc., it adopted the name Siltron. The company’s ownership later changed again: according to the supplied German-language company article, KTB Network Co. Ltd. and Vogo Investment Fund acquired shares from Dongbu Steel in 2006. A major change occurred in 2017. In January of that year, LG and SK Holding announced that SK Holding would acquire the 51% stake in LG Siltron held by LG Electronics. Following the acquisition, the company changed its name to SK Siltron Inc. in August 2017. The same source describes SK Siltron as a subsidiary of SK Group and says the remaining shares are held by KTB Network and Vogo Investment Fund. The company manufactures silicon wafers at facilities in Gumi and Incheon, South Korea. Its products include polished and epitaxial wafers spanning diameters from 150 mm to 450 mm, along with wafers for the solar industry. The supplied source characterizes it as the fourth-largest producer of 300 mm wafers. Beyond these points, the available evidence does not establish further dated developments, named executives, or a detailed account of its present-day market footprint.
