Liang Mong Song is a semiconductor engineer whose career has moved between TSMC, Samsung and SMIC. SMIC's new 5 nm-node processors are likely to be used for AI training and smartphones, and he co-leads that company. After a Berkeley doctorate in 1984, he built a career at TSMC before joining Samsung. A TSMC lawsuit over alleged leaks to Samsung ended with a Supreme Court verdict that barred him from providing services to Samsung until after the end of 2015.
