CEA-LETI extends the transistor dimension scaling by through the use of 3D nanowire FET
CEA-LETI has successfully integrated on the same SOI wafer different types of advanced transistor structures like stacked nanowires transistors, FINFETs and independent dual gate FET, using a common flow compatible with standard planar FDSOI devices.
This achievement open the way to adopting different device structures in the same chip to optimise performance, density and power consumption.
The devices were processed within CEA-LETI facilities where the e-beam lithography platform allowed the fabrication of 15nm gate length devices. The work was carried out in the frame of the French Carnot Institutes initiative and in collaboration with the IMEP Grenoble and STMicroelectronics Crolles.
The full results showing the structures and the electrical results will be presented at IEDM conference next December where CEA-LETI will participate with over 10 papers on different aspects of nanotechnologies, advanced devices and process integration.
Located in Grenoble, Leti (Electronics and Information Technology Laboratory of the French Atomic Energy Commission) is one of the main European applied research centers in electronics. More than 85% of its activity is devoted to research with 350 contracts a year. Since its creation in 1967, Leti has led to the creation of more than 30 start-ups in high-technology. The main areas of activity are micro- and nano-technologies for microelectronics (more Moore, More than Moore and Beyond CMOS), technologies, design and integration of microsystems, photonics and imaging technologies, micro- and nano-technologies for biology and health, communication technologies and nomadic objects.
Leti operates with an annual budget of 174 M€ and employs 1,000 people with, in addition, more than 600 external collaborators (postgraduates, research and corporate partners). Leti has 8,000m² of clean rooms, an equipment portfolio worth 200 M€ and invests more than 40 M€ a year on new equipment. Leti has a dynamic Intellectual Property policy and has filed more than 200 new patent applications in 2007. Instigator of the MINATEC® pole of innovation, CEA Leti is also one of its principal partners, beside the Grenoble INP (Grenoble Institute of Technology) and the local authorities.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.
A warming planet
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
New technique promises tunable laser devices
Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
