Samyang NC Chem

Samyang NC Chem makes specialty chemical materials used inside semiconductor factories, specifically the light-sensitive polymers and photo-acid generators that help etch microscopic circuits onto silicon wafers, as well as intermediate chemicals that clean away residue after the etching step.

It supplies these materials to photoresist and cleaning-fluid makers, who process them further before shipping finished products to chipmakers. Listed on KOSDAQ, Korea's tech and small-cap board, the company focuses entirely on two core semiconductor fabrication steps: the photolithography (circuit-patterning) process and the wafer-cleaning process.
