  • Publication number: 20130084039
    Abstract: A photonic integrated circuit apparatus is disclosed. The apparatus includes a photonic chip and a lens array coupling element. The photonic chip includes a waveguide at a side edge surface of the photonic chip. The lens array coupling element is mounted on a top surface of the photonic chip and on the side edge surface. The coupling element includes a lens array that is configured to modify spot sizes of light traversing to or from the waveguide. The coupling element further includes an overhang on a side of the coupling element that opposes the lens array and that abuts the top surface of the photonic chip. The overhang includes a vertical stop surface that has a depth configured to horizontally align an edge of the waveguide with a focal length of the lens array and that vertically aligns focal points of the lens array with the edge of the waveguide.

  • Patent number: 7755159
    Abstract: A method of fabricating a dielectric film comprising atoms of Si, C, O and H (hereinafter SiCOH) that has improved insulating properties as compared with prior art dielectric films, including prior art SiCOH dielectric films that are not subjected to the inventive deep ultra-violet (DUV) is disclosed. The improved properties include reduced current leakage which is achieved without adversely affecting (increasing) the dielectric constant of the SiCOH dielectric film. In accordance with the present invention, a SiCOH dielectric film exhibiting reduced current leakage and improved reliability is obtained by subjecting an as deposited SiCOH dielectric film to a DUV laser anneal. The DUV laser anneal step of the present invention likely removes the weakly bonded C from the film, thus improving leakage current.
