ET News reports [English] that the price of silicon wafers, the raw material used in the production of 300mm semiconductors, has increased 20% year over year from major manufacturers SK Siltron and SUMCO.

SK Siltron is a recent acquisition of the SK Group, a massive South Korean conglomerate that also includes SK Materials (produces NF3 gas used in semiconductor production) and SK Hynix (a memory chipmaker that regularly appears in our articles on increasing NAND demand). SK Siltron was known as LG Siltron until January, when SK Group purchased 51% of shares from LG for $532 million, and then proceeded to purchase the rest as well (Chairman Choi Tae-Won personally secured 29.4%). LG Siltron sales had suffered since 2012 with an industry increase in silicon wafer production, as well as the aftermath of the 2008 financial crisis--but SK Group’s purchase immediately paid off.
