DNF Co., Ltd. is a South Korea-based specialty chemical and electronic materials manufacturing company engaged in the research, development, synthesis, and commercial production of advanced chemical precursors and functional material solutions for the semiconductor, display, and electronic components industries. Founded in 2001 and headquartered in Daejeon, South Korea, the company operates dedicated research, synthesis, and manufacturing facilities, supplying major integrated device manufacturers, semiconductor foundries, and flat-panel display producers across South Korea, greater East Asia, and global technology markets.
The company's primary product offerings comprise Atomic Layer Deposition (ALD) and Chemical Vapor Deposition (CVD) precursor materials; Double Patterning Technology (DPT) and Quadruple Patterning Technology (QPT) silicon precursors, including DIPAS and chlorosilane derivatives used for sub-nanometer lithography and fine-pitch patterning; High-k dielectric precursors, including zirconium-based, hafnium-based, and titanium-based precursors engineered for high-density dynamic random-access memory (DRAM) capacitor fabrication and advanced logic gates; Low-k dielectric precursors formulated for interlayer dielectric (ILD) insulating films to minimize parasitic capacitance; Spin-on-Carbon (SOC) hardmask materials for high-aspect-ratio etching; metal and conductive barrier layer precursors; chemical mechanical planarization (CMP) slurries; functional optical coatings and barrier films for organic light-emitting diode (OLED) and liquid crystal display (LCD) panels; and specialty chemical additives and functional materials for secondary battery electrodes.
In recent corporate and strategic developments, Solus Advanced Materials acquired a controlling stake in DNF Co., Ltd., making the company a core subsidiary within its electronic materials portfolio to drive supply-chain synergies across semiconductor chemicals and advanced packaging materials. Built upon long-standing technical partnerships and strategic equity investment from Samsung Electronics, DNF Co., Ltd. has expanded its commercialization efforts for next-generation precursor formulations optimized for high-bandwidth memory (HBM), ultra-high-layer 3D NAND flash architectures, and sub-3nm Gate-All-Around (GAA) logic fabrication, while actively advancing operational initiatives in high-purity secondary battery materials and next-generation green chemical technologies.
