Patterns of the thermoelectric iron silicide were fabricated on alumina substrates with a continuous-wave ytterbium fiber laser. The laser irradiation process was further examined to construct an iron silicide device without damaging the substrates upon thermal shock. The multi-step irradiation process of powder mounting and irradiation demonstrated its performance as a thermoelectric device. Furthermore, the mechanism associated with the formation of an iron silicide layer was discussed.
