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

Abstract: This research focuses on the future of integrated circuit (IC) scaling technologies at the device and back end of line (BEOL) level. This work includes high level modeling of different technologies and quantifying potential performance gains on a circuit and system level. From the device side, this research looks at the scaling challenges and the future scaling drivers for conventional charge-based devices implemented at the 7nm technology node and beyond. It examines the system-level performance of stacking device logic as and tunneling field effect transistors (TFET) and their potential as beyond-CMOS devices. Finally, this research models and benchmarks BEOL scaling challenges and evaluates proposed technological advancements such as metal barrier scaling for copper interconnects and replacing local interconnects with ruthenium. Potential impact on performance, power, and area of these interconnect technologies is quantified for fully placed and routed circuits.
