Final Report Summary - FEMTOLITHO (Ultrahigh resolution femtosecond laser lithography for applications in life sciences and display technologies)

In Feb 2015 I began the Marie Curie IEF project FemtoLitho, in the laboratories of Prof. Maria Farsari’s ([e-mail]) group at ULF-FORTH in Heraklion, Crete (Greece).

The main experimental technique to meet the goals of FemtoLitho is two photon polymerization (2PP), where focused femtosecond laser pulses are used to form 3D micro and nanostructures in photoresists. For the fabrication of devices using the 2PP technique, an excellent automation of experimental variables and motion control is needed. The Farsari group has developed a microprocessing system consisting of the femtosecond laser with automated power, polarization and focus plane control in addition to motion control of the high resolution stages. These elements of control during an experiment enable better reproducibility but also a much faster efficiency of experiments. While at FORTH, I was trained on these important skills and methods. The 2PP laser system developed by the Farsari group is particularly important as it allows one to conceive a 3D structure of arbitrary geometry by designing it first using a CAD software program. This gives the flexibility to fabricate novel and complex 3D structures which would be particularly useful for FemtoLitho.

The experience gained working alongside Prof. Maria Farsari was invaluable to my development as a researcher and a person. I will greatly benefit from these important experiences on the next chapter in his career as a researcher at Politecnico di Milano, where I was recently awarded the prestigious SIR grant worth €500,000, the Italian equivalent of the ERC Starting Grant. Thanks to the Marie Curie experience, I am now in a great position to be one of the future scientific leaders in Europe.
