Oussama Moutanabbir

Silicon-Integrated Quantum Electronics and Photonics


For decades, compound semiconductors have been successfully used for a precise and simultaneous control of lattice parameters and bandgap structures bringing to existence a variety of functional heterostructures and low-dimensional systems. Extending this paradigm to group IV semiconductors will be a true breakthrough that will pave the way for scalable, compact, and silicon-compatible optoelectronic, photonic, and quantum devices. With this perspective, I will describe strategies and new material systems to independently engineer lattice dynamics and band structure in group IV semiconductors. The materials to be discussed are grown epitaxially using chemical vapor deposition system equipped with isotopically enriched precursors with purity higher than 99.9%: 28SiH4, 29SiH4, 30SiH4, 74GeH4, and 76GeH4 in addition to Sn precursors.  I will address the epitaxial growth of (Si)GeSn semiconductors and their relevance for Si-based mid-infrared photonics and quantum computing. I will also describe our progress in the use of stable isotopes as an additional degree of freedom in the growth of semiconductor quantum structures. This isotope engineering provides a wealth of opportunities to manipulate their basic properties, design an entirely new class of devices, and highlight subtle but important fundamental processes.


Oussama Moutanabbir is a Professor holding a Canada Research Chair in Nano and Quantum Semiconductors at the department of Engineering Physics of École Polytechnique de Montréal (Canada). As a follow of Japan Society of the Promotion of Science, he worked at the Quantum Computing Lab at Keio University (Japan) and before taking position in Montreal, he was a Project Leader at the Max Planck Institute of Microstructure Physics (Germany). He also held a joint appointment as an Invited Researcher at RIKEN Institute of Advanced Science (Japan) between 2009 and 2015. His research is in materials physics and engineering encompassing fundamental scientific and industrial activities. His main work focuses on expanding the fundamental understanding of basic physical properties of a variety of group IV nanomaterials and quantum structures. Additionally, his group also made significant contributions leading to commercial products through numerous joint collaborations with high-tech companies focusing primarily on large-scale integration processes for sensing, imaging, optoelectronic, photovoltaic, and electronic applications. For instance, his recent project with Teldyne-Dalsa has led to the commercialization in 2018 of the first made-in-Canada uncooled thermal and infrared cameras. This project was awarded the ADRIQ’s Innovation Award, the ADRIQ’s Partnership Award, and the 2019 NSERC’s Synergy Award.

The Role of UCSB Nanolab in accelerating the Commercialization of 650V GaN-on-Si HEMTs at Transphorm based in Goleta,CA : Lessons for RIT to leverage thirty year strength in Microelectronics for the Upstate NY region based startups


This talk illustrates how GaN-on-Si technology was developed and then rolled out in collaboration with academia for the world’s first highly reliable 650V GaN HEMT [2,3,4,5,6,7,8] by demonstrating three years of manufacturing data of since ramp. This technology was initially developed in a pilot line in Transphorm Goleta, CA and then later ported into a Si-CMOS compatible 6-inch foundry at AFSW(Aizu Fujitsu Semiconductor Wafers Solution Ltd). Data set generated from over three thousand wafers worth of data spread over three generations of technology nodes covering multiple products and packages post qualification is presented Silicon manufacturing processes are employed including gold-free, and avoiding the use of evaporation/liftoff typical to compound semiconductors. Best practice of defect detection, failure analysis and process control methods from Si manufacturing industry have been employed to maintain and improve yield for this new technology. Probe yield and line yield for the GaN process now matches that of mature Si-CMOS process running in the same fabrication facilityWide bandgap high-speed and high- voltage GaN devices significantly reduce the system size and improve energy efficiency of power conversion in all areas of electricity conversion, ranging from PV inverters to electric vehicles. The results below demonstrates that GaN high volume production is now a reality. This is the current third stage of Transphorm funded by Series C and D investment led by KKR and one other strategic European IDM. However, prior to this phase of mass production since 2015 there were two earlier phases described below which may be relevant for RIT.


Seasoned manager with over twenty years of yield enhancement, technology development, operations, and business development experience in the semiconductor wafer fabrication and equipment industry. He has broad experience of technology development and transfer to manufacturing spanning Fortune 500 companies Applied Materials, Cypress Semi and Maxim Integrated products rising through the ranks to functional management role during his first fifteen years since RIT. He started his industrial career at Applied Materials in the area of Dry Etch as an applications engineer between 1995-2000. Thereafter he joined Cypress San Jose R&D  Fab developing  Dry Etch processes for 90 and 65 nm SRAMs at Cypress transferred to Minnesota Production fab. His first  Operations Management role was at Maxim Dallas  where he ran the Photo/Etch group -Process and Equipment engineers for a 24x7 fab producing 3000 + wafers per month for 0.35 um BiCMOS and Analog/Mixed Signal power management products.  Since 2011, he has been with a KKR backed Santa Barbara based startup Transphorm developing wide bandgap GaN  based IC for efficient and compact charging solutions aimed at electric car on board charger, server power supply, PV inverter and Servo motor driver applications. At Transphorm, he runs all of front end manufacturing  working across functional environments interacting with device, integration, module, packaging and equipment teams spanning Santa Barbara, Aizu Wakamatsu Japan, Hsinchu Taiwan and Penang Malaysia. During this period Transphorm moved from Series B to Series D funding graduating from the backing of Sand hill road early investors like Kleiner Perkins, Lux Capital and Google Ventures to late stage investors like KKR, the Japanese Sovereign Wealth fund INCJ and a large unnamed strategic chip company. All of this has been possible because Transphorm IC chips are now in mass production and doing well in field trials at strategic customers. One key accomplishment led by Saurabh was the development of industrial scale supply chain with Fujitsu as JV partner for front end manufacturing enabling laboratory scale technology developed at UCSB Umesh Mishra lab to move to mass manufacturing in Fujitsu Foundry. He holds a Masters in Engineering from Rochester Institute of Technology -Microelectronics Engineering'94 on a SRC funded full fellowship. Maxim integrated sponsored him to Harvard Business School - Program for Leadership Development in 2007-08. 











Shamsul Arafin

Compound III-V Semiconductor based Classical and Non-Classical Light Emitters at Visible through Mid-Infrared


III-V compound semiconductor materials and photonic devices are expected to play an important role in addressing ongoing and future challenges in the field of communication and sensing. Ultra high-speed, short and long-range communication links; portable and power-efficient computing devices; solid-state lighting; ultra-fast interconnects; and high-performance optical sensors in sensing applications are critically depending on the success of next-generation emerging semiconductor materials and the resulting photonic devices. In this talk, I will mainly discuss about recent cutting-edge research efforts made by my team at OSU on III-V semiconductor materials and photonic devices. In particular, an emphasis will be given on nitride-based electrically­-pumped lasers with emission wavelengths of the ultraviolet and blue regions. Design, fabrication and testing results of such lasers will also be presented here. In addition, I will present the recent theoretical and experimental results of advanced antimonide-based lasers, being useful for sensing and defense applications. Considering a significant promise of quantum technologies, I will also briefly show how my research enters into the quantum territory for developing non-classical devices including single photon emitters that could enable robust communication-based applications, such as electronic warfare, signal intelligence, and counter-digital radio frequency memory.

Ferroelectronics: From Memory to Computing


Research discovery of ferroelectricity in doped hafnium dioxide thin films has ignited tremendous activity in exploration of ferroelectric FETs for a range of applications from low-power logic to embedded non-volatile memory and to novel computing paradigms. In this talk, key milestones in the evolution of Ferroelectric Field Effect Transistors (FeFETs) and the emergence of a versatile ferroelectronic platform are presented. FeFET exhibits superior energy efficiency and high performance as embedded nonvolatile memory. When embedded into logic, such as SRAM or D-flip-flop, nonvolatile processor can be designed, which is critical for intermittent computing with unreliable power. The partial polarization switching in multi-domain ferroelectric can be harnessed to develop analog synaptic weight cell for deep learning accelerators. To further improve the energy-efficiency of computation, ferroelectric in-memory computing hardware primitive is designed, with one prominent example of ferroelectric TCAM. Utilizing the ferroelectric switching dynamics, ferroelectric neuron with intrinsic homeostasis can be realized to enable a unified ferroelectric platform for spiking neural network. From all these developments, ferroelectric emerges as a highly promising platform for various exciting applications.


Kai Ni received the B.S. degree in Electrical Engineering from University of Science and Technology of China, Hefei, China in 2011, and Ph.D. degree of Electrical Engineering from Vanderbilt University, Nashville, TN, USA in 2016 by working on characterization, modeling, and reliability of III-V MOSFETs. Since then, he became a postdoctoral associate at University of Notre Dame, working on ferroelectric devices for nonvolatile memory and novel computing paradigms. He is now an assistant professor in Microsystems Engineering at Rochester Institute of Technology. He has around 60 publications in top journals and conference proceedings, including Nature Electronics, IEDM, VLSI Symposium, IRPS, EDL, etc. His current interests lie in nanoelectronic devices empowering unconventional computing, AI accelerator, security and memory technology.


Shelby Nelson

Thin Glass Substrates for Advanced Packaging Applications


Glass substrates with fine-pitch through-glass via (TGV) technology is a promising approach to system-in-a-package integration.  Millimeter wave applications, in particular, benefit from the superior RF properties, dimensional stability, and surface properties of glass.  Glass can be made in very thin sheets (<100 um) which aids in integration and eliminates the need for back-grinding operations.  The biggest challenge to adopting glass as an advanced microelectronics packaging substrate is the existence of gaps in the supply chain, caused primarily by the difficulty in handling large, thin glass substrates using existing automation and processing equipment.  This talk presents Mosaic Microsystem’s temporary bonding technology that allows the substrates to be processed in a semiconductor fab environment without the need to modify existing equipment.  The technique allows the thin glass/silicon pair to be processed leveraging existing processes, with only a mechanical de-bond to yield finished substrates. The numerous benefits to this approach will be discussed.
