Abstract: In one embodiment, a package substrate includes a substrate core, buildup layers, and one or more conductive traces. The substrate core includes at least one dielectric layer with hollow glass fibers. The buildup layers include dielectric layers below and above the substrate core.

Abstract: Embodiments include devices, systems and processes for using a combined confocal Raman microscope for inspecting a photo resist film material layer formed on the top surface of a layer of a substrate package, to detect border defects between regions of light exposed (e.g., cured) and unexposed (e.g., uncured) resist film material. Use of the confocal Raman microscope may provide a 3D photo-resist chemical imaging and characterization technique based on combining (1) Raman spectroscopy to identify the borders between regions of light exposed and unexposed resist along XY planes, with (2) Confocal imaging to select a Z-height of the XY planes scanned. Such detection provides fast, high resolution, non-destructive in-line inspection, and improves technical development of polymerization profiles of the resist film material.

Abstract: A coated paper product including a paper layer and a polymer layer, wherein the polymer layer includes a polylactide polymer composition having a ratio of Mz to Mn of greater than about 6. The polymer composition, when melted, exhibits a die swell of greater than about 1.25 for a melt flow index of greater than about 2. Polymer lactide compositions, methods of manufacturing the polymer composition and the coated paper product, and articles produced therefrom are also described.

Abstract: A water ski handle system designed to partially absorb and evenly distribute forces generated on the handle component and tow line while skiing. The handle system includes a handle component with two L-shaped corner struts attached to its opposite, opened ends. Each corner strut includes a rigid bushing member which mechanically connects to an end on the handle component, and a perpendicularly aligned long leg member which projects in a forward direction parallel to the longitudinal axis of the main tow line. A continuous, L-shaped inner passageway is formed inside each corner strut through which the end of the tow line passes to connect to the handle component. The corner radius of the inner passageway is relatively large so that point loading on the tow line is substantially reduced.
