Heterogeneous Integration Fabric

In the past five decades, the semiconductor industry has gone through two distinct eras of scaling: the geometric (or classical) scaling era and the equivalent (or effective) scaling era. As transistor and memory features approach sub-10 nanometer, it is apparent that room for further scaling in the horizontal plane is running out. Further, the rise of data abundant computing is exacerbating the interconnect bottleneck that exists in conventional computing architecture between the compute cores and the memory blocks. In this talk, I will discuss how electronics is poised to enter a new, third, era of scaling – hyperscaling – in which resources are added in a flexible way when needed to meet the demands of data abundant workloads. This era will be driven by advances in embedded non-volatile memories, hybrid devices with merged logic and memory functionalities, monolithic three-dimensional integration, and heterogeneous integration techniques.


Suman Datta is the Stinson Chair Professor of Nanotechnology in Department of Electrical Engineering at the University of Notre Dame. Prior to that, he was a Professor of Electrical Engineering at The Pennsylvania State University, University Park, from 2007 to 2011. From 1999 till 2007, he was in the Advanced Transistor Group at Intel Corporation, Hillsboro, where he developed several generations of high-performance logic transistor technologies including high-k/metal gate, Tri-gate and non-silicon channel CMOS transistors. His research group focuses on emerging devices that enable new computing models. He is a recipient of the Intel Achievement Award (2003), the Intel Logic Technology Quality Award (2002), the Penn State Engineering Alumni Association (PSEAS) Outstanding Research Award (2012), the SEMI Award for North America (2012), IEEE Device Research Conference Best Paper Award (2010, 2011) and the PSEAS Premier Research Award (2015).  He is a Fellow of IEEE and the National Academy of Inventors (NAI). He has published over 350 journal and refereed conference papers and holds 185 patents related to semiconductors. He is the Director of a multi-university advanced microelectronics research center, called the ASCENT, funded by the Semiconductor Research Corporation (SRC) and the Defense Advanced Research Projects Agency (DARPA). He will serve as the General Chair of the 2020 IEEE International Electron Device Meeting (IEDM).

Printing technology has evolved from traditional quick writing tools to the modern
manufacturing methods for functional devices and systems. The benefits of printing-based
manufacturing include less material waste, fast-turn around prototyping due to simple
design customization and wide substrate compatibility. In this presentation, all-printed
supercapacitors, where all the components are made by printing, are introduced. Because
the device is manufactured only by printing, the complexity of manufacturing facilities can
be minimized and the resource efficiency and versatility are maximized, which are
particularly important in places where the supply of material and human resources are
limited such as rural areas, environmental monitoring of nuclear sites and space exploration
missions. We have fabricated electrical double layer capacitors and pseudocapacitors, both
with high electrochemical performance and cyclic durability and the results will be discussed
in detail.

Quantitative Plasmonic Sensing with Single-Chip Inkjet Dispense Surface Enhanced Raman Spectroscopy (ID-SERS)

Dr. Fausto D’Apuzzo, Optical Scientist, HP Labs

In this talk, I will present our Laboratory work on highly-quantitative plasmonic sensing based on Surface Enhanced Raman Spectroscopy (SERS). I will first describe our nano-imprinted SERS substrate architecture and performance. Then I will show how inkjet dispensing can be used in conjunction with SERS to encode each sensor with a calibration pattern of microdroplets (~30 pico-liters), with the aim of locally calibrating sensor performance. This way, we demonstrate that Measurement Uncertainty of the SERS signal can be reduced below 2%, which to our knowledge, is a new record for plasmonic sensing platform. Furthermore, the use of inkjet dispensing in combination with Raman mapping improves assay throughput (100-fold) and reduces sample volume consumption (105-fold) in an automated and reproducible fashion. Since this approach overcomes important practical hurdles, we believe that this work reignites interest in the potential commercialization of plasmonic-based chemical sensors.

Recent paper for reference:  A Generalizable Single-Chip Calibration Method for Highly Quantitative SERS via Inkjet Dispense.




Dr. Fausto D’Apuzzo is Optical Scientist at HP Labs, working on the Life Science team. His research interests are in optics systems, plasmonics and metamaterials for bio-sensing, with a focus on Surface Enhanced Raman Spectroscopy (SERS). He started investigating plasmonic systems since his master (2011) and PhD at the University of Rome “Sapienza”, before holding a postdoc position at L. Berkeley National Labs (LBNL) studying 2D plasmonic systems with Synchrotron Nano-Spectroscopy. He interned as an Optical Engineer at ACAMP (Alberta, Canada) before joining HP Labs (2018-present) where he is developing plasmonic sensing systems for quantitative chemical analysis.
