Femtosecond laser ablation of different materials is becoming more and more important in micro- and nanomachining fields. The cutting precision and cost-effectiveness related to this method are turning it into a valid alternative to traditional methods. Coupling it with PDMS-assisted microtransfer printing could establish a completely new process of fabrication. In this work, ablation parameters were optimized to cut square shapes (sometimes referred to as “inks”) on the silicon device layer of a thin-film SOI (silicon-on-insulator) wafer. Specifically, the effect of repetition rate, power, number of passes, feed rate and cutting direction was investigated. A scanning electron microscope was used to determine the quality of the cuts. Qualit...
