Control of sidewall roughness formation in through-silicon via etch at non-cryogenic temperatures
- SPIE Advanced Lithography 2022
Sebastian Engelmann received his Ph.D. in Materials Science at the University of Maryland, College Park in 2008. His main research activities in Prof. Gottlieb Oehrlein's group were improving the fundamental understanding of plasma-polymer interactions with main focus on 193nm PR resist materials interactions.
He then joined the Advanced Plasma Processing group at the IBM T.J. Watson Research Center in Yorktown Heights, N.Y, where he was developing plasma etch processes to support current and future device generations for exploratory CMOS device research and devices beyond the CMOS era. His main research activities are developing plasma processes that enable the integration of Trigate and Nanowire device geometries, novel materials (SiGe, III-V etc) or completely new technology apporaches (Photonics, MRAM, packaging etc.). Since 2015 he was also manager of the plasma processing group, looking at pioneering new uses of plasma etch technology in conventional and novel applications.
He recently joined the IBM Quantum organization to drive hardware component development for current and future quantum computing systems and is leading global efforts on developing supply chain and hardware ecosystems in this space.
