Abstract :
The growth mechanism of a semiconducting β-FeSi2 film has been investigated by in situ reflective high energy electron diffraction observation combined with ex situ AES depth profile and cross-section transmission electron microscopy. At the initial stage, a metastable cubic γ-FeSi2 phase has been detected on both Si(100) and (111) wafers. A multilayer structure Fe-rich silicide FeSi1+x/Si has been revealed. During the deposition, β-FeSi2 only directly formed on the top layer at high temperature
