Keynote Presentations

Keynote 1 - Advanced Heterogeneous Integration Technology - A Key Enabler for Electronic Systems

Rolf Aschenbrenner, Fraunhofer Institute for Reliability and Microintegration, Berlin, Germany

The semiconductor industry is facing a new era in which device scaling and cost reduction will no longer continue on the path followed for the past few decades. The integration of more transistors into a monolithic IC is becoming more difficult and expensive at each node. Semiconductor companies are now looking for technological solutions to bridge the gap and improve cost performance, while at the same time adding more functionality through integration.
An attractive solution is heterogeneous integration (HI), that uses advanced packaging technologies to integrate devices, which can be designed and manufactured separately with the most suitable process technology and in the most optimized way. The package is also the ideal HI platform because it provides short connections, power efficient arrangement and high bandwidth between components in a compact form factor.
For example, with heterogeneous integration one can bring multiple chips (or chiplets) together into a single package. It elevates a conceptually similar multi-chip module to the next level by leveraging advanced wafer- or panel level manufacturing technologies.
This presentation will describe the value of advanced packaging as an HI platform. Key features in leading edge 2D and 3D technologies, such as wafer and panel level technologies will be described and new package developments from SoC to chiplet architecture will be presented. Challenges and opportunities in developing robust advanced package architectures will be discussed.

Rolf Aschenbrenner received the B. S. degree in mechanical engineering from the University for Applied Science, Gießen, Germany, in 1986 and the M.S. degree in physics from the University of Gießen, Germany, in 1991. From 1991 to 1992 he has worked at the University of Gießen and in 1993, he joined the Research Center for Microperipheric Technologies at the Technical University of Berlin. Since March 1994 he has been employed at the Fraunhofer Institute for Reliability and Microintegration Berlin (IZM) where he is presently the Deputy Director and Head of the Department System Integration and lnterconnection Technologies.

He received the iNEMI International Recognition Award in 2005, the CPMT David Feldman Outstanding Contribution Award 2013 and the European Semi Award 2016 .

As a member of the IEEE EPS Society Board of Governors Rolf Aschenbrenner has worked as a European representative on the Conference Advisory Board Committee, and has played  an active role in the globalization of IEEE EPS in terms of membership  and chapter  development.  He served as IEEE EPS Vice President, Technical and IEEE EPS Vice President, Conferences.

Keynote 3-1 - Sustainable Lithium-Ion Batteries

Ulla Lassi, Applied Chemistry and Process Chemistry, University of Oulu, Finland

The demand for lithium-ion batteries is growing rapidly due to the increasing popularity of electric vehicles, portable devices, and energy storage from renewable energy sources, particularly household electricity generated by wind power and solar cells. This means increasing battery capacity need, and new Gigafactories are being built in Europe. Further, several investment plans for the manufacture of batteries and battery chemicals have also been published. The growing need for batteries will significantly increase the need for both primary battery minerals and recycled materials. However, these secondary materials alone are not enough to cover even the current need for battery materials. Therefore, we need responsible mining and sustainable battery mineral processing. Discussions on sustainability raise often the role of cobalt in battery metals, its availability and, in particular, the ethical aspects related to cobalt processing chain. Cobalt has been paid too much attention in this regard, as already in existing lithium-ion batteries; the use of cobalt is quite low and will decrease significantly with new NMC chemistries and even completely cobalt-free chemistries. In addition, cobalt can be efficiently recycled from lithium-ion batteries, as can nickel. In addition to battery metals, the focus should also be on current cell manufacturing processes, which typically use toxic solvents and fluorinated binders or electrolyte salts. These compounds pose challenges not only from the viewpoint of battery cells recycling but also from the point of view of ecology and safety. In our own research, we have recently focused on new cell manufacturing methods. At the same time, we have been able to replace e.g. harmful NMP solvent and binders with new material choices without compromising the performance of the battery cell itself. Such a greener cell manufacturing technology would also like to be transferred to the production of more and more battery factories in the short term.

Keynote 3-3 - CNF-MIM Technology, Enabling the Worlds Thinnest Capacitor

Maria Bylund, Smoltek AB, Gothenburg, Sweden

This keynote will present a novel technology (CNF-MIM) combining Carbon Nanofiber (CNF) materials and MIM (metal-insulator-metal)-like technology, enabling capacitors with total thickness lower than 40 µm suitable for use in future miniaturized electronics. The ultra-thin and discrete CNF-MIM capacitors have been manufactured and characterized on several substrates, showing excellent electrical properties such as high capacitance density of several hundreds of nF/mm2 , ESR (equivalent series resistance) in the mOhm range, low ESL (equivalent series inductance) on the order of 10 pH thus being promising for a multitude of applications within the semiconductor industry. To assess the long-term durability, CNF-MIM capacitors have also been subjected to prolonged exposure to high temperature and constant voltage bias environments following a HTS (high temperature storage) and BTS (biased temperature stress) standard. The CNF-MIM capacitor show initial robustness against degradation in these scenarios.

Maria Bylund received her B.Sc. degree of Applied Mechanics and her Master’s degree of Materials Science and Engineering from the Chalmers University of Technology in 2009 and 2011, respectively. She worked as test engineer at SKF Sverige AB; as CAE Engineer and then as Project Assistant at the Chalmers University of Technology, all in Gothenburg, Sweden. Since 2018, she has been working as R&D Engineer at Smoltek AB, which company has focused towards the area of nanostructure technology. They are – among other things – working in the field of nanofabrication towards the semiconductor industry. Her tasks are to plan, perform and thoroughly document and evaluate projects within this area, using advanced equipment and methods common to the nanofabrication area as well as advanced analysis methods. She commonly does growth of carbon nanofibers (CNFs) in a PECVD (Plasma Enhanced Chemical Vapor Deposition) system, photolithography, different kinds of metal depositions such as sputtering, physical vapor deposition (PVD) and atomic layer deposition (ALD) and other processing can include e.g. wet and dry etching, heat treatments and such. Testing and confirming of processing and properties in between process steps as well as after completed production is paramount to the production. Electrical properties are evaluated using a Parameter Analyzer Probing Station and a Vector Network Analyzer (VNA) connected to a probing station. Visual evaluation is mainly done with the help of optical light microscopy and Scanning Electron Microscopy (SEM). A great portion of her work is performed at Myfab, a Nano fabrication facility located at Chalmers University of Technology. This laboratory is a cleanroom, which requires special training to access and individual personal licenses to operate the machines.

Keynote 3-4 - Nanomaterial-Enabled Soft Electronics

Yong Zhu, Andrew A. Adams Distinguished Professor, North Carolina State University (NCSU), USA

Highly sensitive wearable sensors that can be conformably attached to human skin or integrated with textiles to monitor the physiological parameters of human body or the surrounding environment have garnered tremendous interest. Owing to the large surface area and outstanding material properties, nanomaterials are promising building blocks for wearable sensors. In this lecture I will start with a brief overview of the recent advances in the nanomaterial-enabled soft electronics (e.g., flexible, stretchable, and wearable sensors and soft robotics). Integration of multiple sensors for multimodal sensing and integration with other components into wearable systems will be summarized. Then I will present the array of wearable sensors developed in my group using silver nanowire (AgNW) composites including strain/pressure sensors, hydration sensors, temperature sensors, antennas and etc. AgNW composites offer outstanding combination of high conductivity and high stretchability. I will highlight a critical issue for developing AgNW-based stretchable devices – scalable nanomanufacturing. Electronic waste has become a pressing issue that poses a threat to health and environment. Here I will propose a recycling approach to address the issue using AgNWs as an example. I will conclude my talk with some recent work extending from wearable sensors for human health to wearable plant sensors and soft robotics.

Prof. Yong Zhu is the Andrew A. Adams Distinguished Professor in the Department of Mechanical and Aerospace Engineering, with affiliated appointments in the Departments of Materials Science and Engineering and Biomedical Engineering, at North Carolina State University (NCSU). His group conducts research at the intersection of solid mechanics and micro/nano-technology, including nanomechanics, interfacial mechanics, micro/nano-electromechanical systems, and nanomaterial-enabled stretchable electronics.
