Neodymium ions were implanted into silicon epitaxial layer with MEWA ion source in low ion flux. Nd silicides with good properties were synthesized after rapid thermal annealing (RTA). Comprehensive analyses including scanning electron microscope (SEM)
reflection high energy electron diffraction (RHEED) and X-ray diffraction (XRD) show that the Nd silicides formed by MEVVA ion implantation have good crystalline quality. The XRD result indicates a phase transition from Nd5Si4 to NdSi
