DONGIL TECHNOLGY CO.,LTD.

Our ESD ionizers and sensors provide precise static control for advanced semiconductor and display manufacturing processes. Using corona discharge technology, they generate positive and negative ions to neutralize electrostatic charges accumulated on insulating surfaces such as wafers and films, helping prevent particle attraction, ESD-related process defects, and yield loss in both front-end and back-end processes.

Proven through qualification by global customers, our solutions deliver reliable static control performance for increasingly demanding microfabrication environments. CE and UL compliance ensures product safety and quality reliability. With in-house development and manufacturing of key components, including high-voltage power supplies (HVPS), we offer vertically integrated solutions with strong cost competitiveness—approximately 30% more competitive than major global alternatives.

Our EMI/EMC filters effectively suppress high-frequency electromagnetic noise generated by semiconductor equipment and production lines, minimizing interference between systems and helping ensure stable processes, reliable equipment operation, and consistent performance.

Backed by over 30 years of accumulated expertise and a leading market position in Korea, our filters have a proven track record of reliable supply to global customers. Compliance with major international standards and certifications, including KC, UL, and CE, demonstrates product quality and safety. With overseas manufacturing capabilities, we offer flexible support for diverse product requirements, stable global supply, and strong cost competitiveness compared with major global competitors.
