Abstract: A method for assembling a two-dimensional fiber array launcher assembly. The method includes providing an alignment structure having a two-dimensional alignment plate with holes at one end and a two-dimensional beam shaper with micro-lenses at an opposite end. An endcap having a fiber attached thereto is systematically positioned in each hole, and is aligned with one of the micro-lenses with a high precision tolerance. The aligned endcap is then secured in the hole using a curable glue. This process is continued until all of the holes have aligned endcaps. If one of the endcaps is mis-aligned or becomes damaged, the glue can be heated and the endcap realigned or replaced.

Abstract: Embodiments of the invention generally relate to a method and apparatus for curing dielectric material deposited in trenches or gaps in the surface of a substrate to produce a feature free of voids and seams. In one embodiment, the dielectric material is steam annealed while being exposed to ultraviolet radiation. In one embodiment, the dielectric material is further thermally annealed in a nitrogen environment.

Abstract: Embodiments in accordance with the present invention relate to multi-stage curing processes for chemical vapor deposited low K materials. In certain embodiments, a combination of electron beam irradiation and thermal exposure steps may be employed to control selective outgassing of porogens incorporated into the film, resulting in the formation of nanopores. In accordance with one specific embodiment, a low K layer resulting from reaction between a silicon-containing component and a non-silicon containing component featuring labile groups, may be cured by the initial application of thermal energy, followed by the application of radiation in the form of an electron beam.

Abstract: A method of processing a substrate including depositing a low dielectric constant film comprising silicon, carbon, and oxygen on the substrate and depositing an oxide rich cap on the low dielectric constant film is provided. The low dielectric constant film is deposited from a gas mixture comprising an organosilicon compound and an oxidizing gas in the presence of RF power in a chamber. The RF power and a flow of the organosilicon compound and the oxidizing gas are continued in the chamber after the deposition of the low dielectric constant film at flow rates sufficient to deposit an oxide rich cap on the low dielectric constant film.

Abstract: An ultraviolet (UV) cure chamber enables curing a dielectric material disposed on a substrate and in situ cleaning thereof. A tandem process chamber provides two separate and adjacent process regions defined by a body covered with a lid having windows aligned respectively above each process region. One or more UV bulbs per process region that are covered by housings coupled to the lid emit UV light directed through the windows onto substrates located within the process regions. The UV bulbs can be an array of light emitting diodes or bulbs utilizing a source such as microwave or radio frequency. The UV light can be pulsed during a cure process. Using oxygen radical/ozone generated remotely and/or in-situ accomplishes cleaning of the chamber. Use of lamp arrays, relative motion of the substrate and lamp head, and real-time modification of lamp reflector shape and/or position can enhance uniformity of substrate illumination.
