Missions

The Post-doc researcher will be in charge of the structural and chemical advanced characterization of the different test structures that will be fabricated within the IT2-FR project (IC Technology for the 2nm node), carried out in collaboration with several French industrial partners operating in the semiconductor technology domain. The objective of this project is to explore, develop and demonstrate technology options that will enable 2nm CMOS technology.
A special attention will be devoted to the investigation of the impact of nanosecond laser annealing on different types of materials, with the goal of integrating this annealing technique into the manufacturing processes of advanced electronic devices.
The two main studies will concern (i) the engineering of Cu and/or Ru based metallic interconnects (i.e. modification and control of grain size, elemental diffusion at interfaces...) and (ii) the engineering of source/drain junctions (Si and SiGe doping by implantation or in situ methods, hyperdoping by group VI impurities implants...).
The post-doc researcher will also collaborate with the other researchers of the LAAS team in the framework of various national and European projects currently in progress.

Activities

- Structural and chemical characterization of thin semiconductor or metal layers following a nanosecond laser anneal, by several TEM-based techniques, including HREM, STEM/HAADF, STEM/EDX and Weak Beam Dark Field
- Identification of the crystalline or poly-crystalline structure of the various materials studied using high resolution TEM techniques
- Identification of the best procedures for the preparation of thin TEM lamellas
- Identification of complementary experimental techniques for the investigation of the above mentioned phenomena (Electron BackScatter Diffraction, Atom Probe Tomography, X-ray diffraction, Photoluminescence…)

Skills

- PhD in physics, materials science or nanotechnology
- Solid skills in advanced structural nano-characterisation methods
- Ability to fluently write and speak in English due to the frequently planned international meetings and written reporting activities as well as continuous mail and telephone exchanges within the different projects in progress
- Good team-working capacity (several interaction to occur with both the project partners as well as the engineers/technical staff working in the local laboratory)

Work Context

With a large number of permanent researchers, engineers and PhD students as well as strong interactions with industry, the LAAS-CNRS stands at the crossing between scientific research, innovation and applications. The LAAS-CNRS possesses one of the most important technological installations dedicated to research in France, with an ultra-modern cleanroom of 1600m² as well as a characterization platform (1200 m2) hosting numerous equipment for the electrical, optical, HF and chemical/bio characterization of micro and nano-systems. In particular, a SEM/FIB equipment is available at LAAS for the fabrication of thin lamellas for TEM analysis. State-of-the-art TEM equipment are available at accessible at the UMS R. Castaing characterization platform of the University of Toulouse.
The project will take place mainly in the host laboratory in Toulouse, but the post-doc researcher will work in a very stimulating research environment in the framework of numerous academic and industrial collaborations at French and European level.
