DNFCo

DNFCo makes the specialty chemical materials used to build the ultra-thin layers inside semiconductor chips, the films that insulate, conduct, and define the microscopic patterns etched onto each chip.

It supplies these thin-film precursor materials to chipmakers and equipment companies as part of the semiconductor manufacturing supply chain. Listed on KOSDAQ, Korea's tech-focused stock exchange, the company earns the large majority of its revenue from its semiconductor materials segment, with a smaller portion from other chemical materials.
