    Industry Activity

    Joshua (Yong-Hoon) Yoo has been in the electrostatic control industry since 1994 for ionization, high voltage powers and ESD measurement. Since joining the EOS/ESD Association in 2000, he is a active member of everal standard working groups, including the EOS/ESD Association and SEMI ESD Taskforce. He worked as a Sr. Manager for Application and Business Development of Ion System products at MKS Korea.
    In 2003, he established Core Insight, Inc. to provide EOS/ESD process assessment and training services in the semiconductor, flat panel display, automotive, and electronics industries, and to provide electrostatic control programs and solutions. He providing consulting services to global electronics companies such as Nvidia, Foxconn, Continental Automotives, Teradyne, ASE Korea, Tales, Corning and many others to improve their yield, quality, and reliability issues. He developed alternative symmetrical ionization technologies for contamination and ESD control of FPD industry and QuadPoint Steady-State DC Bar ionization system for AI related HPC application.
    He has presented technical papers at several EOS/ESD symposiums and is recognized as a pioneer in the FPD ESD control application. He served as the Chairman of the FPD Working Group and is very active members for working groups such as Ionization, Process Assessment, EOS Best Practice, Work Surfaces, Packaging, HandTool, Electrostatic Attraction and Footwear and Flooring Systems. In September 2011, he founded the Korean branch of the ESD Association and took office as its representative, growing it into one of the most active EOS/ESD Association branches in the world. From 2016 to 2018, he served as an Elected Board of Director of the EOS/ESD Association, and in 2019, the Korean branch was converted to an independent organization and relaunched as the ‘Korea EOS/ESD Association.’ Recently, he has also been contributing to yield improvement through solving EOS/ESD problems in the AI and HPC fields and Advanced Package Devices.
