edfas.org 11 ELECTRONIC DEVICE FAILURE ANALYSIS | VOLUME 28 NO. 4 ABOUT THE AUTHOR Dr. Sam Lin is the regional marketing manager for Thermo Fisher Scientific, responsible for the semiconductor microscopy, advanced benchmarking, and failure analysis business across the Asia-Pacific and Japan (APJ) region. Lin received his Ph.D. in materials science and engineering from National Tsing Hua University, Taiwan. He began his career at FEI, later Thermo Fisher Scientific, and subsequently served as technical manager at BESI, leading hybrid bonding technology deployment in Taiwan and supporting technology introduction, process development, pre-sales, system implementation, and customer engagement. Since rejoining Thermo Fisher Scientific in 2022, he has leveraged his technical expertise together with strategic marketing leadership to help customers address increasingly complex semiconductor challenges through advanced benchmarking, failure analysis, and process characterization solutions. 4.
