Epitaxial growth processes of Si from ArF laser-excited Si 2H6 supersonic free jets have been investigated using reflection high-energy electron diffraction, growth rate, and atomic force microscopy measurements. Layer-by-layer epitaxial growth was observed at substrate temperature Ts=670°C regardless of the laser excitation. However, it was found that island growth was predominant at T s=550°C without the laser excitation, while layer-by-layer growth occurred by using the ArF laser-excited Si2H6 jet probably due to an enhancement of surface reactions induced by precursor species obtained from laser-excited Si2H6.
