    摘要: For end-to-end alignment of two optical waveguides one of which is in the form of a strip buried in a semiconductor wafer, a longitudinal lateral mark is used constituted by the flank of a valley etched in the wafer and self-aligned to the strip formed beforehand. To achieve this self-alignment a protection layer is deposited in the area in which the mark is to be formed, a register layer is deposited on top of the protection layer and a photosensitive resin is deposited on top of these layers and the substrate. First selective etching eliminates the register layer at the location of the valley of the mark. Second and third selective etching respectively etch the lateral channels of the strip and then the valley of the mark.

    摘要: 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.
