HanWool Semiconductor

HanWool Semiconductor makes automated visual-inspection machines that check electronic components, display panels, and battery films for defects during manufacturing.

Its three main product lines serve makers of tiny passive components (such as capacitors and resistors), LCD and OLED display panels, and copper foil films used in rechargeable batteries. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company derives its revenue roughly equally from domestic and export customers. Its core technology is machine-vision software, algorithms that process camera images to detect microscopic flaws at high speed.
