In response to a request from Samsung Electronics, PKC, a prominent South Korean chemical company, is set to invest tens of billions of won in expanding the annual production capacity of semiconductor chlorine gas at its Gunsan facility. The planned increase will elevate production from the current range of 1,400 to 1,500 tons per year to a new range of 2,100 to 2,200 tons, marking a substantial 50% rise. This strategic move is primarily driven by the escalating demand for etching gases, which has been spurred by advancements in high-density NAND flash memory stacking technology. Additionally, it fulfills Samsung Electronics' request for a larger supply of hydrogen chloride, a crucial component in the wafer cleaning and etching processes essential for semiconductor fabrication. Hydrogen chloride is synthesized through the reaction of chlorine gas with hydrogen gas, highlighting the interconnectedness of these materials in the semiconductor manufacturing ecosystem.
