Recently, microwave processing has emerged as a rapid and energy-efficient alternative to conventional hotplate annealing. By using microwave annealing, we reduced processing time to one-tenth of the traditional methods while simultaneously enhancing crystal quality.

Furthermore, we successfully mitigated the edge effect caused by electromagnetic wave diffraction, a common limitation of microwave annealing of semiconductors. We expanded classical nucleation theory with microwave-specific modifications, establishing a comprehensive framework that links microwave power to nucleation rates and grain growth.

A study of the melting behavior of Si-kerf agglomerates under inert and vacuum conditions was carried out.

No single melt was produced under inert conditions between 1600 °C and 1700 °C, while a single melt with a shiny metallic luster was produced under vacuum conditions at the same temperature range. It is shown that the melting under inert gas occurs mostly via the joining of tiny silicon droplets surrounded by a thin oxide layer, and the formation of a silicon melt with an oxide layer around it.
