LK Chem

LK Chem makes specialty chemicals called precursors and ligands, the reactive materials deposited in ultra-thin layers onto silicon wafers to give semiconductor chips their electrical properties.

It supplies these materials to the semiconductor industry, sitting upstream in the chip-manufacturing supply chain. Listed on KOSDAQ, Korea's tech-focused small-cap board, the company's core products are high-dielectric and low-dielectric precursor materials used in atomic layer deposition, a precise layer-by-layer thin-film process, alongside synthesis-based photovoltaic materials and other specialty chemicals made to customer specification.
