Germanium and Silica co-deposition in MCVD process is studied with varying the flow ratio of GeCl4/SiCl4 at high temperature without phosphorus. The range of ratio is from 0.1 to 0.6 with temperature deposition 2100°C. The incorporation of germanium in silica matrix is deduced from the EPMA SEM-EDX. The experimental result is compared to theory such as thickness deposited layer and mole fraction of germanium in silica.
