31P ions were implanted into high-purity SiO2 sphere powders of 20 to approximately 30 μmφ at 50 keV energy with 1.5×1017/cm2 dose utilizing a modified medium-current implanter and, for reference, into SiO2 plate at 200 keV with 1.0×1018/cm2 utilizing a conventional medium-current implanter. P doping profile was measured by 3D-SIMS with 0.5 μmφ Cs+ primary beam. Buried high P-concentration region was revealed. Implanted structure was observed by XTEM, EPMA and μ-RHEED: tens-nm-diameter sphere-like balls of phospho-silicate glass were distributed around the projected range. The top surface was almost unchanged from the substrate and was so thick as to prevent P elusion into hot water.
