Semi-insulating polycrystalline silicon films have been used as matching layers in micro-zone-melting recrystallization experiments of silicon-on-insulator (SOI) structures. The effect of the laser irradiation on the structural composition and crystallographic properties has been investigated by transmission electron microscopy and Auger electron spectroscopy. CO2 laser processing has been shown to lead to redistribution of oxygen and interface segregation of thin oxide and silicon zones.
