This Tutorial is organized by the EU project NANOTEC
The outcome of the EU project NANOTEC will be presented in this Tuitorial.
The project NANO-TEC (Ecosystems Technology and Design for Nanoelectronics) is a
support action funded by the European Commission under number 257964. The aim of
NANO-TEC is to address the gap between technology and design in Nanoelectronics in
the area of Beyond CMOS. Within the scope of NANO-TEC, a number of workshops have
been organized, where specific ‘Beyond CMOS’ device concepts were presented and
discussed by experts in the field. Some categories of beyond CMOS devices were
selected, that were benchmarked and a swot analysis was carried out. The outcome of
this study will be presented during the tutorial by different partners of the project.

13:45-14:00 EU project NANOTEC on ECOSYSTEMS TECHNOLOGY & DESIGN for
NANOELECTRONICS: an experience in Europe

The project NANO‐TEC (Ecosystems Technology and Design for Nanoelectronics) is a support
action funded by the European Commission under number 257964. The aim of NANO‐TEC is to
address the gap between technology and design in Nanoelectronics in the area of Beyond CMOS.
While a recognised European strength is in heterogeneous integration, the academic community is
also very strong in research addressing ways to carry out information processing operations using
different concepts, state variables and associated technologies. A second aim of NANO‐TEC is to
consolidate and strengthen the academic community in Europe in the area of Beyond CMOS. This
trend is presently decoupled from the research in design and it is this gap which weakens the impact
of the progress being made in Beyond CMOS, since ways to realise devices operating under real
conditions in a competitive manner to existing technologies are simply not viable without a design
To this end NANO‐TEC carries out a continued consultation and analysis of research needs
and trends based on a workshop series with invited experts from the Americas, Asia and Europe
covering topics such as Beyond CMOS device concepts and design, benchmarking and a SWOT
analysis of new devices. Progress made so far towards the stated aims will be presented in this
tutorial by the different speakers.
NANO‐TEC is led by the Catalan Institute of Nanotechnology and is funded by the ICT theme
of the 7th Framework programme of the European Commission. There are 10 partners involved in the
NANO‐TEC project besides the coordinator: these are Finnish Valtion Teknillinen Tutkimuskeskus,
German Edacentrum GmbH and Foschungszentrum Juelich GmbH, Chalmers Technical University of
Sweden, Polish Institute of Electron Technology, Delft University of Technology from the
Netherlands, Greek National Centre for Scientific Research “Demokritos”, Tyndall National Institute
from Ireland, the Ecole Politechnique Fédérale de Lausanne and French Centre National de la
Recherche Scientifique. All the partners are experienced in working in large consortia distributed
over the European Union and contribute their organisational and integrative expertise together with
visionary research and ambitious goals. The scientific and social challenges of NANO‐TEC can only be
achieved with a constellation like NANO‐TEC aided by global experts and strong links to industry,
which will ensure abroad coverage of its topic at European level.

14:00-14:30 Benchmarking of Beyond CMOS
Jouni Ahopelto, VTT Technical Research Centre of Finland, Helsinki, Finland
Beyond CMOS devices can range from molecular electronics to quantum computing, exploit other
state variables than charges and have a very wide span in maturity. This makes benchmarking
challenging and direct comparison of devices practically impossible. Semiconductor Research
Corporation carried out a few years ago in US benchmarking of emerging devices against state of the
art CMOS switches and the results were promising1. Within NANO‐TEC we have benchmarked
devices from the following categories: Molecular Electronics, MEMS, Solid‐State Quantum
Computing, Spintronics, Nanowires, Memristors and Graphene, and tried to take into account the
specific properties of each of the device families. We will describe the methodology used and give
some examples of the outcome. We will also address some of the difficulties identified during the

14:30-15:00 A SWOT Analysis of ‘Beyond CMOS’
Mart Graef, DIMES, Delft Institute of Microsystems and Nanoelectronics, Delft University
of Technology, The Netherlands
CMOS‐based technology has been the backbone for the semiconductor industry for many decades,
and over this period it has been the essential enabler for the continuation of Moore’s Law. However,
the CMOS device architecture has constraints that will limit its applicability in the future. These
limitations are associated with physical barriers (entering atomic dimensions), economic
considerations (manufacturing costs) and new trends in nanoelectronics (from ‘More Moore’, i.e.
monolithic digital systems to ‘More than Moore’, i.e. heterogeneous multifunctional systems).
One of the objectives of the NANO‐TEC coordination action is to charter the technology landscape
that lies ‘beyond CMOS’. This is achieved by assessing the requirements for proposed new device
concepts, selecting the most promising technologies and designs, benchmarking these against
existing devices, and performing a SWOT analysis for the benchmarked devices.
Within the scope of NANO‐TEC, a number of workshops have been organized, where specific ‘Beyond
CMOS’ device concepts were presented and discussed by experts in the field. The 3rd of these
workshops, held in May 2012, focused on a SWOT analysis of ‘Beyond CMOS’ options. The topics that
were reviewed included the level of maturity of these technologies, design issues, scientific
challenges, compatibility with existing semiconductor processing, application perspectives, and
infrastructural aspects. The results of this SWOT analysis will be presented and discussed.
15:00-15:30 Case study: The case of nanowire transistor
Guilhem Larrieu, LAAS-CNRS, Toulouse, France
The aim of NANOTEC is to explore the potential of the technologies claimed for the “Beyond CMOS”
era. The strategy is not to directly compare, to “benchmark”, the performance of the emerging
devices against the current state‐of‐the‐art CMOS devices but rather more like mapping and
identifying the potential for future ICT applications, bearing in mind that some relevant properties
are required to be fulfilled. The challenges include, among others, power consumption, speed,
integration prospects, flexibility for new architectures and manufacturability. The parameter
windows facilitating integration of the selected devices should be estimated and a frame for
potential architectures to run a logic application should be sketched, including identification of the
possible improvements in device properties and the bottlenecks in fabrication. Several key
parameters have been selected and will be discussed.
In order to show our analysis procedure, we will provide an example of candidate in the field of
‘Beyond CMOS’ devices: the nano‐wire transistors. This device will illustrate the benchmarking and
integration criteria in particular scalability, manufacturability, reliability and reproducibility.
15:30-16:00 Coffee Break
16:00-16:30 Information processing paradigms of the post CMOS era: devices
Alain Cappy, IEMN-UMR, Villeneuve D’Ascq, France
The energy efficiency becomes an essential criterion used for information processing technologies. It
is indeed for energetic reasons that the scaling down rules (R. Dennard, 1974) that guided the
evolution of the micro‐ and nanoelectronics for almost 40 years cannot be any more applied today.
The consequences of this change are manyfold: the stagnation of the clock frequency (2‐3 GHz since
2004) and the bigger complexity of microprocessor architectures (multicore). The rather bad energy
efficiency of the current systems also constitutes a brake in the development of mobile applications
and its impact on the environment (electric consumption) becomes more and more significant.
It becomes thus urgent to propose new paradigms of information processing capable of reducing the
energy consumption in a drastic way while improving the performances as well. Based on multiple
disciplines (thermodynamics, material physics, nanosciences and the nanotechnologies, information
theory, computer science, neurosciences) researches on these new paradigms need necessarily a
multidisciplinary approach covering, at a minimal level, the material ( devices fabrication) and
software aspects (system architecture, circuit design…).
After a presentation of the scientific and technological questions which arise, we will propose some
possible ways for information processing of the post CMOS era. We will show in particular the
interest of neuromorphic architectures for many applications, in particular, image processing.
