Low-power electronics benefits from the use of non-volatile magnetic memory (MRAM) integrated with CMOS devices to build nonvolatile (NV) logic. This solution is of high interest for connected objects and IoT. The basic element of an MRAM is the Magnetic Tunnel Junction (MTJ), is com-posed of a magnetic reference layer with a fixed magnetization direction and a storage layer that has a reversible magnetization, separated by a thin insulating barrier.
The ANR project MISTRAL is proposing innovative solutions for improving the energy footprint of the cryptography embedded in connected objects while keeping the security of the device at its highest standard. It is therefore needed to benchmark lightweight cryptography algorithms and solutions to be proposed as countermeasures against fault attacks. These benchmarks are needed to report electrical parameters of silicon requirements and power consumption. From this analysis, specifications of countermeasures against fault attacks can be proposed, taking into account the benefits from STT-MRAM/CMOS integration.
To realize this benchmarking it is necessary to realize nanofabricated MRAM devices with 20 to 100nm lateral size and their electrical characterization to get a better insight on the stack and its sensitivity to various classes of attack.
- Nanofabrication of magnetic tunnel junctions to nano pillars of 20-100nm lateral dimension
- Yield improvement of critical fabrication steps (ion-beam etching, electrical contact)
- Structural (SEM, FIB) and electrical characterization
- Process flow improvements to sub-10nm lateral sizes. Development of process modules.
- PhD in nanotechnology, nanoelectronics. Successful demonstrations of nanofabrication in a clean room environment are mandatory.
- Affinity for experimental work is required and some knowledge of process modules (e-beam lithography, ion beam etching, reactive ion etching, metallization) is a plus.
- Electrical characterization and reporting of process results.
- Good team-work capacity (interactions with other team members and technical staff
Spintec is a research laboratory affiliated with CEA, CNRS and Univ. Grenoble Alpes of about 100 persons. Our mission is to bring fundamental research in spintronic devices to innovative industrial applications. We have been developing MRAM solutions since 2002 with the development and integration of process flows. The developed concepts lead to several start-up companies in the field (Crocus Technology, Hprobe, Antaios). The nanofabrication process takes place in a modern cleanroom environment using tools of the PTA technology platform (http://pta-grenoble.com/) belonging to the Renatech network. The project will be carried out in the host laboratory in Grenoble in the context of a multi-partner project.
