  • Publication number: 20130288485
    Abstract: A method of forming a dielectric layer is described. The method first deposits an initially-flowable layer on a substrate. The initially-flowable layer is then densified by exposing the substrate to a high-density plasma (HDP). Essentially no additional material is deposited on the initially-flowable layer, in embodiments, but the impact of the accelerated ionic species serves to condense the layer and increase the etch tolerance of the processed layer.

  • Publication number: 20130097947
    Abstract: A steel structure including pre-stressing brackets for improving load-carrying capacity and serviceability comprises: a steel girder; a plurality of connecting brackets connected to the bottom surface of the steel girder spaced and apart from one; and a cover plate connected to the bottom surfaces of the connecting brackets. Since the cover plate is installed regardless of the connecting portion of the steel girder, pre-stressing section can be consecutively formed therefore pre-stress effect is improved. Moreover, since the connecting brackets space the cover plate a constant distance from the steel girder, the moment of inertia is increased so the span of a bridge might be increased.
