KnJ Co., Ltd. is a South Korea-based manufacturing company primarily engaged in the development, fabrication, and distribution of high-performance semiconductor consumable components and automated display manufacturing equipment. Founded in 2005 and headquartered in Asan-si, Chungcheongnam-do, South Korea, the company operates through two primary business segments: Semiconductor Materials & Parts and Display Equipment. The Semiconductor Materials & Parts division specializes in chemical vapor deposition silicon carbide (CVD-SiC) consumables engineered for dry plasma etching processes in advanced 3D NAND flash memory and DRAM semiconductor fabrication, with core product offerings including CVD-SiC focus rings; SiC edge rings; SiC showerheads; SiC guide rings; and precision silicon and quartz chamber parts engineered to withstand extreme plasma environments, reduce particle contamination, and extend process chamber replacement cycles. The Display Equipment division develops and manufactures automated precision machinery for flat panel, OLED, and flexible display production lines, with core equipment offerings including automated glass edge grinders; edge polishing systems; panel chamfering machines; ultra-thin glass (UTG) edge profiling systems; and optical inspection and laser processing apparatus. KnJ Co., Ltd. supplies integrated device manufacturers, semiconductor original equipment manufacturers, and flat panel display producers across South Korea, China, Taiwan, and Southeast Asia. In recent operational developments, the company has executed multi-phase manufacturing capacity expansions for its CVD-SiC product line by adding high-temperature CVD synthesis chambers at its domestic facilities to support heightened demand resulting from increasing layer counts in high-aspect-ratio 3D NAND fabrication. Additionally, the company has broadened its product portfolio into next-generation SiC showerhead components and advanced its display equipment engineering toward specialized edge finishing and inspection systems for foldable ultra-thin glass and automotive OLED displays.
