LOTVacuum makes dry vacuum pumps, motorized devices that remove air and gases to create the controlled, near-airless conditions required for manufacturing semiconductors and displays.
Its pumps are used directly inside chipmakers' production lines, where they maintain the precise vacuum levels each process step demands and handle the chemical by-products generated along the way. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company earns the large majority of its revenue from its vacuum pump segment, with equipment and other services making up a much smaller share.
