  • Patent number: 11746408
    Abstract: Embodiments of the disclosed subject matter provide a vapor distribution manifold that ejects organic vapor laden gas into a chamber and withdraws chamber gas, where vapor ejected from the manifold is incident on, and condenses onto, a deposition surface within the chamber that moves relative to one or more print heads in a direction orthogonal to a platen normal and a linear extent of the manifold. The volumetric flow of gas withdrawn by the manifold from the chamber may be greater than the volumetric flow of gas injected into the chamber by the manifold. The net outflow of gas from the chamber through the manifold may prevent organic vapor from diffusing beyond the extent of the gap between the manifold and deposition surface. The manifold may be configured so that long axes of delivery and exhaust apertures are perpendicular to a print direction.

  • Patent number: 7160746
    Abstract: A method of depositing a top clad layer for an optical waveguide of a planar lightwave circuit. A GeBPSG top clad layer for an optical waveguide structure of a planar lightwave circuit is fabricated such that the top clad layer comprises doped silica glass, wherein the dopant includes Ge (Germanium), P (Phosphorus), and B (Boron). In depositing a top clad layer for the optical waveguide, three separate doping gasses (e.g., GeH4, PH3, and B2H6) are added during the PECVD (plasma enhanced chemical vapor deposition) process to make Ge, P and B doped silica glass (GeBPSG). The ratio of the Ge, P, and B dopants is configured to reduce the formation of crystallization areas within the top clad layer and maintain a constant refractive index within the top clad layer across an anneal temperature range. A thermal anneal process for the top clad layer can be a temperature within a range of 950C to 1050C.
