There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Hanju OhHanju Oh received the first place poster award at the IEEE Global Interposer Technology Conference, held November 5-7 at the Georgia Tech Global Learning Center. A Ph.D. student in the Georgia Tech School of Electrical and Computer Engineering (ECE), Oh is advised by ECE Associate Professor Muhannad Bakir and ECE Professor and College of Engineering Dean Gary May.
The title of the award-winning poster was “Electrical Interconnect and Microfluidic Cooling within 3D ICs and Silicon Interposer.” Oh’s coauthors on the work were Li Zheng and Yue Zhang, his fellow Ph.D. students in the Integrated 3D Systems Group, which is led by Bakir.
The poster presented a three-dimensional integrated circuit (3D IC) system with an embedded microfluidic cooling heat sink (MFHS). In the proposed 3D IC system, high power tiers contain embedded MFHS and high-aspect ratio (23:1) through-silicon vias (TSVs) routed through the integrated MFHS. Each tier has dedicated solder-based electrical and fluidic microbumps for electrical interconnection and fluidic delivery, respectively. In addition, thermal characterization of a microfluidic heat sink with embedded TSVs was also presented for the first time.
