Posdoc – Development of microstructuration techniques using laser photo-thermal ablation

Background: Foldable, thin, light-weight, stackable, high performance – that’s the promise that flexible electronics and integration of highly heterogeneous functional and structural materials holds today. Smart systems featuring ubiquitous intelligence such as wireless sensor networks, micro-aerial vehicles, embedded defense, security and biomedicine chips, environment monitoring and smart textiles are all applications that flexible electronics and heterogeneous integration would make take off. To realize that objectives, advanced very thin film and flexible/conformable electronics and microsystems comprising digital, embedded memories and analogue signal processing, RF circuitry, antennas, sensors, actuators, microfluidics need to be developed. In that context, IEMN develops a flagship research project on flexible electronics featuring two distinctive trademarks: i) high performance multi-Ghz flexible electronics ii) heterogeneous integration of smart materials and functional blocks onto mechanically flexible/stretchable substrates.

Description of work: Within the frame of the LEAF Equipex project, IEMN has acquired advanced laser micromachining systems (multi-wavelength femtosecond and nanosecond) to develop original processes for material structuring compatible with properties of flexibility, conformability and stretchability of plastic substrates. The overall objective is to develop the necessary know-how around these equipments for a wide range of processes (ablation, cutting, scribing, drilling) and materials (semiconconductors, metals, polymers…). The mission naturally covers process optimization and characterization using advanced microscopy capabilities (automated interferometric, SEM, AFM…). The candidate will take an active role in the orientation of other running projects covering interconnects, device and system assembly on flexible/stretchable films. He is also expected to contribute or manage scientific reporting as well as publications.
