Industry Activity

Joshua (Yong Hoon) Yoo has been involved in the static control industry since 1994 for ionization and ESD test equipment business. He started technical assessment and training services for semiconductor, flat panel display, automotive and general electronics industry. He joined the EOS/ESD Association at 2000 and active member of many standard working groups EOS/ESD Association and SEMI ESD taskforce. He was Sr. Technologist at MKS Korea for Ion System products.

For advanced static control program, solutions and services based in Korea, Joshua established Core Insight, Inc. in 2003. He is published author of technical papers at several EOS/ESD Symposium events and recognized as pioneer for FPD ESD control application. He serviced global electronic companies for improved of static related yield impacts, quality and reliability issues. Also, He invented alternative room ionization technology for the FPD industry for both contamination and ESD control.

He was a chair of FPD working group and a member of Ionization, Process Assessment, EOS Best Practice, CBE and High Reliability working groups and others. In September 2011, Joshua founded and became a president of Korea Local chapter of the ESD Association and with his efforts, Korea Chapter became one of the very active local chapters of EOS/ESD Association over the world. He served as elected Board of Director for EOS/ESD Association during 2016~2018. In 2019, Korea Chapter of ESD Association became Korea EOS/ESD Association as fully independent and standard organization in Korea.
