GENESIS platform temporarily closed for upgrades

The GENESIS neutron facility is currently undergoing several improvement works and is closed for external users until November 2019. These upgrades together with the new shielding configuration installed in early 2019, will allow increasing the flux up to ten times the current limit.

The GENESIS platform (Generator of Neutrons for Science and IrradiationS) is hosted by the Laboratory of Subatomic Physics & Cosmology (LPSC) in Grenoble. It proposes access to an accelerator-based neutron source which can provide an intense flux of 2.5 MeV or 14 MeV neutrons at the best European level. The accelerator, designed and built at LPSC, was recently upgraded and equipped with a compact ECR ion source, developed at LPSC, capable of delivering a continuous deuteron beam up to 1 mA at 220 keV.

The GENESIS platform is one of PAC-G’s irradiation facilities. It is mainly used for single-event effects testing in microelectronics.

How science supports industry

On occasion of the International MicroNanoConference 2018, our colleague Rafael Varela Della Giustina was interviewed to talk about how science support industry. He also offered three application cases illustrating how the research facilities, such as the ESRF, ILL, LPSC and CEA-Leti; can support growth and competitiveness in microelectronics.

Often seen as two different worlds, science and industry evolve together. As industry addresses specific market needs, R&D activities (and in broader perspective: science) provide the key enabling technologies to do so. Think of it as building bricks: people want houses with particular characteristics => that constitutes a market. The industry is responsible for the construction and the assembly of those houses. As for Science and Research, they develop the bricks and the tools needed to build those structures.

This metaphor is particularly true when it comes to microelectronics. For years, joint collaborative research efforts were made in order to continue scaling down transistor sizes. This would in turn allow higher performance, lower price and lower power microchips that would trigger the development of that new ultrafast computer or that super cool smartphone. In a sense, the whole industry advanced together in one very well-known direction.

Recently, with technology nodes down to some tens of nanometres scaling has shown its limitations and this logic inversed its direction. As instance, it is the customer need for connected objects that drives the technological developments and specification for IoT devices. Consequently, a whole set of new technologies came to light, in different sizes, shapes and compositions, in order to allow new product developments: TSVs, bonding techniques, heterogeneous integration, copper pillars for flip-chips, new wafer-level packaging technologies, new materials, advanced substrates, bandgap engineering, III-V materials and so on. This “soup” of technological choices demands a lot of basic and applied research. More than ever, industry and science are tightly holding hands together.

With the speech “Large Scale instruments tackling nanoscale characterization challenges in microelectronics” at the International MicroNano Conference 2018, Rafael will go through three application cases illustrating how these research facilities can support growth and competitiveness in microelectronics:

  • The use of Neutron Reflectivity (NR) to characterise the penetration of water into direct bonded SiO2/SiO2 interface. Read more
  • In-situ X-ray diffraction study of solid-state reaction of Ni and GeSn on Si substrate. Smooth phase transformation is observed during the annealing and some kinetic parameters could be withdrawn. Read more
  • X-ray nano-tomography with 30nm spatial resolution at LSF for the characterization of Through Silicon Vias (TSV) and Copper Pillars (CuP).

The DG for Research & Innovation for the EU visiting the ESRF and ILL members of PAC-G

Mr Jean-Eric Paquet, Director General for Research & Innovation European Commission, came to visit the BM05, the ESRF’s beamline co-founded by the IRT NanoElec

On 8th January, the European Photons and Neutrons Campus had the pleasure to host Jean-Eric Paquet, European Commission Director-General for Research and Innovation, European Union, who came to discover the industrial and academic landscape based in Grenoble and to visit the European Synchrotron (ESRF) and the European Neutron Source – the Institute Laue-Langevin (ILL).

During his visit to the ESRF, Jean Susini (Director of Research, ESRF) introduced Mr Paquet to the team managing the Platform for Advanced Characterisation – Grenoble (PAC-G) – and to the PAC-G platform hosted on ESRF’s BM05, which is 50% funded by the IRT Nanoelec. This unique platform includes: a five-circle goniometer, a robot that automatically positions 300 mm and 200 mm wafers on the diffractometer, a mirror to focus the beam to less than 30 microns, an optical microscope to locate the areas (measuring just several microns) to be observed and two 2D detectors effective at high levels of X-ray synchrotron radiation and offering spatial resolution of 60 microns. One of its big advantages is the large size of one of the two detectors (25 cm x 2.5 cm), which makes it possible to rapidly map reciprocal space. Three years since the initial investment, the PAC-G team was able to show Mr Paquet the range of operational, innovative and commercial services tailored for the nano- and micro-electronics industry.

We asked M. Paquet, what was his impression after this day: “How do you consider the role of the ESRF and ILL in the European scenario, with regard to new trends in innovation?”

Jean-Eric Paquet:

The main focus of Research Infrastructures is to perform curiosity-driven fundamental research. However, Research Infrastructures – such as the ESRF and ILL – also have an innovation potential that goes much beyond the direct socio-economic impact in their local and regional ecosystems.

More and more, Research Infrastructures are service providers to industrial players’ needs, such as nano-characterisation of materials, which can have a huge impact on citizens’ lives in areas such as battery development, energy provision, cancer treatment, environmental monitoring, among many others.

Partnering with industry for the supply of high tech components and launching new initiatives, such as ATTRACT, also lays down the foundations for disruptive innovation in key critical technologies. Examples of these developments, which also develop new markets, include the new generation of detectors, virtual astronomical observatories, lenses, protein scanners, magnets, energy efficient computers, etc.

Adding to this, I would also highlight they are the perfect multi-disciplinary test-beds, as their users – scientists and industrial players – cover virtually all fields of science, from physics, chemistry and biology, to energy, medicine, cultural heritage and engineering.

Below we've listed some of the most common questions that we get asked. Please click on a question to see the answer. If you have other questions for us then please contact us

PAC-G stands for Platform for Advanced Characterisation Grenoble. It is a single entry-point for the advanced characterization services provided by the European Synchrotron (ESRF), the European neutron source (ILL) and the Laboratory of Subatomic physics and cosmology (LPSC). The particularity of the PAC-G is to address the semiconductors market, specifically micro- and nano- electronics instead of having a broad range of sectors. The access is done in a fast and cost- competitive manner, with confidentiality levels adapted to your needs, which makes it particularly interesting for industrial research. Our scientists will set up the instruments beamlines and, depending on the service chosen, will perform the measurements and analyze the data.

No need for proposals, peer reviews or publications. We secure beamtime and also provide advice on the best technique (or combination of techniques) to use based on your characterization challenge.

The PAC-G was created within the frame of the French Technological Research Institute (IRT) Nanoelec, funded under the Investissements d’avenir economic stimulus package, (grant ANR-10-AIRT-05).


PAC-G aim is to open the large-scale facilities of Grenoble to the industry with characterisation services.
