BCnC

BCnC makes consumable parts, such as rings, tubes, domes, and liners, used inside the machines that manufacture semiconductor chips, specifically during the etching and thin-film deposition steps of the production process.

Listed on KOSDAQ, Korea's tech-focused small-cap board, it supplies these quartz, silicon, and ceramic components directly to chipmakers as well as to semiconductor equipment makers. Synthetic quartz parts account for the majority of its revenue, with the remainder split among natural quartz, silicon, ceramic, and other materials.
