High Dose Implantation of Nitrogen and Phosphor into Silica Glass

Abstract

ABSTRACTThe surface chemistry of silica glass implanted with N+ or P+ ions has been studied. The X-ray photoelectron spectroscopy (XPS) spectra of N(1s) for silica glass implanted with N+ shows the possibility of the formation of oxynitride glass. For the first time, the effect of the implantation of N+ and additional Si+ on the surface chemistry of silica glass has been studied and found to be significant in increasing the nitrogen concentration in the silica glass. The peak concentration of N increases several times, and does not change even if the sample is annealed at 900°C. The XPS spectra of P(2p) for silica glass implanted with P+ ions shows two interactions, both P-O and P-P. Therefore, the XPS spectra shows the possibility for the formation of phosphosilicate glass using P+ implantation into silica glass.
