Defects in semiconductors and displays are often caused by dust and moisture.<br />To prevent these problems and improve productivity, researchers have developed a technology that can transport large items using electromagnets.<br />Park Se-young has more. <br /> Semiconductor and OLED display production requires a process called evaporation, a method of thin-film deposition.<br />This requires a clean manufacturing environment, as dust or moisture can cause defects.<br />Korean researchers have developed a technology that uses electromagnetic levitation to move large items without making dust.<br /><br /> "This non-contact method does not generate dust or moisture. It can be used in vacuums, and be used for chemical vapor deposition and the OLED manufacturing process."<br /><br /> In a vacuum, the technology uses electromagnets to lift an 800-kilogram carrier and transport it between the motors.<br />The technology was originally used for magnetic levitation trains at Incheon International Airport.<br /> Free of wheels, the technique does not generate dust and can maintain a steady speed through precision control.<br />The technology has been transferred to a local company to be further developed and commercialized.<br />Park Se-young, Arirang News. <br />
