LB Semicon

LB Semicon handles the final stages of chip production: packaging bare semiconductor chips into protective housings and testing them to confirm they work correctly, a service known in the industry as OSAT (outsourced semiconductor assembly and test).

Its customers are chipmakers that design non-memory chips such as display driver chips, smartphone processors, power-management chips, and image sensors. The company also runs a secondary business recovering battery materials, including cobalt, nickel, manganese, and lithium, from electric-vehicle batteries and energy-storage systems for recycling and reuse. It is listed on KOSDAQ, South Korea's technology and small-cap stock board.
