DNF

DNF Co., Ltd. operates as a specialized chemical manufacturer focused on the semiconductor and display industries. Founded in 2001 by CEO Kim Myung-woon, the company is headquartered in Daejeon, South Korea, and has established itself as a key supplier of advanced materials for electronic components. The firm's core business revolves around the development and production of precursors, which are critical chemical compounds used in the manufacturing of semiconductors.

The product portfolio includes materials for DRAMs, flash memories, and wafer patterning processes. Key offerings consist of amorphous carbon layer (ACL) products used for hard mask films, double patterning technology (DPT) precursors, and materials for atomic layer chemical vapor deposition (AL CVD). DNF serves a global client base, distributing its products to domestic markets in South Korea as well as to overseas markets, including China, Japan, and Taiwan. A significant milestone for the company was the development of a precursor for aluminum chemical vapor deposition in collaboration with Samsung in 2005, marking its entry into the chip production market. This relationship was further solidified in 2021 when Samsung Electronics made a strategic equity investment of 21 billion won, acquiring a 7% stake and becoming the second-largest shareholder.

The company's business model is centered on the manufacturing and sale of these high-purity chemical materials directly to semiconductor and display manufacturers. In addition to its primary focus, DNF also supplies coating materials for the automotive and construction sectors and is involved in real estate rentals. In August 2023, it was announced that Soulbrain Holdings, another major Korean materials company, intended to acquire a controlling stake in DNF to expand its own semiconductor materials portfolio. This strategic acquisition, valued at around 100 billion won, targets DNF's precursor business and assets, excluding its subsidiaries Chemoptics and DNF Advanced Materials.
