Postdoc – High frequency performance of materials for flexible electronics

Background: Foldable, thin, light-weight, stackable, high performance – this is 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 the two distinctive trademarks: i) high performance multi-GHz flexible electronics ii) heterogeneous integration of smart materials and functional blocks onto mechanically flexible/stretchable substrates. In support to this scientific/technological program, the LEAF Equipex platform provides innovative laser-based micro-patterning techniques.

Description of work: The candidate will be expected to work in the context of a collaboration between the Nano and Microsystems (NAM6) and Microelectronics (MICROELEC) teams at IEMN and the Laboratoire de Mécanique de Lille (LML). The work will entail design issues of flexible electronic test samples, fabrication of samples involving thin film deposition/processing techniques using equipment acquired within the LEAF project. The candidate will be expected to play a key role in the setting up of a novel test rig at IEMN in order to characterize microelectronic materials (e.g. metals for transmission lines and contacts) at high frequencies using vector network analyzers. By working in collaboration with the LML it will be possible to investigate – in parallel – damage in such materials and its effect of HF performances. The candidate will take an active role in the orientation of this part of the project and be expected to write scientific article and participle at international conferences.
