Abstract
Lasers have been used in research for processing materials for many years. As of late more and more lasers are introduced in production lines where electronic and optical devices are fabricated. It is expected that the future of micro and nano-device fabrication will involve further the use of lasers. In this seminar the basics of UV laser processing of thin film materials will be presented, with emphasis to the potential of the technique for realising flexible electronics. Whether it is laser ablation for the creation of tracks, laser annealing for the activation of a dopant by localised heat treatment, laser sintering for the effective removal of a solvent, or laser melting for the formation of nanoparticles, there are 10 parameters that govern the process and that must be tuned on a case by case optimization. Case studies of different classes of materials will be presented, namely phosphor thin films for light emitting applications, transparent conducting oxides for use as electrodes in optoelectronic devices and metal thin films turned into nanoparticles for plasmonic applications.
