2.5D and 3D Integrated Microsystem Technologies for Applications in Advanced Computing and Bioelectronics

Speaker: Muhannad Bakir

Abstract: Arguably, there has never been a more exciting time in the field of microelectronics in which so many revolutionary, rather than evolutionary, technologies are needed to continue performance scaling. This seminar will focus on innovative system integration technologies and architectures. First, we present a 2.5D integration platform for high-performance computing systems using “interposer bridging” in which a silicon interposer is used to bridge multiple packages in order to attain high-bandwidth density and low-energy ‘off-package’ communication; in such manner, we can form large scale contiguous silicon systems with dense interconnects; frequency- and time-domain measurements of the 2.5D system are presented. Second, we present 3D stacking architectures featuring submicron diameter TSVs along with modeling frameworks for power delivery and thermal maps for the quick analysis (i.e., ‘what if’ type questions) of technology parameters on performance. Moreover, we discuss and experimentally present air-gap based thermal isolation in 3D ICs for local thermal decoupling of temperature sensitive devices. We also present advanced cooling architectures for 3D ICs including the first experimental integration of monolithic microfluidic cooling into a 28 nm Stratix V FPGA and report the resulting throughput and temperature improvements. Lastly, we briefly discuss our recent work in 3D stacked biosensor platforms for cellular monitoring.
