LTC

LTC makes specialty liquid chemicals used to strip and clean photoresist, the light-sensitive coating applied and then removed during the manufacture of display panels and semiconductor chips.

It supplies these process chemicals to display makers and semiconductor companies in South Korea, and through subsidiaries also provides wet-process chemicals, chemical delivery systems, and wafer-cleaning equipment to chip manufacturers. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company's core revenue comes from photoresist stripper and thinner products for display panel production, while newer lines, including photoresist materials for small and mid-sized OLED panels and ceramic materials for solid-oxide fuel cells, are in development or early commercialization.
