Abstract
A method of fabricating a component having a crystalline silicon substrate includes the steps of depositing a layer of silica onto a crystalline silicon substrate, this silica layer being doped with dopants, and then treating the substrate. Before the doped silica layer is deposited, a barrier layer is formed on the substrate, consisting of a barrier material opposing diffusion of the dopants. The doped silica layer is deposited onto this barrier layer. The invention finds one particular application in connecting flat bundles of fibers in communication networks.
