LB Semicon is a South Korean semiconductor company listed on KOSDAQ, Korea's technology and small-cap stock exchange.
It operates in the back-end segment of the semiconductor supply chain, which covers the later-stage manufacturing steps, such as packaging and testing, that transform fabricated wafers into finished chips ready for use in electronic devices. Companies in this part of the supply chain typically provide services to chip designers and integrated device manufacturers who outsource these production steps. LB Semicon's revenue has grown year over year, though the company is currently operating at a loss.

Back-end semiconductor services are a distinct outsourced manufacturing niche in Korea, separate from chip design or front-end wafer fabrication, meaning LB Semicon's business depends on order volumes from chip makers rather than on proprietary product sales.
