    摘要: A chip carrier substrate includes a capacitor aperture and a laterally separated via aperture, each located within a substrate. The capacitor aperture is formed with a narrower linewidth and shallower depth than the via aperture incident to a microloading effect within a plasma etch method that is used for simultaneously etching the capacitor aperture and the via aperture within the substrate. Subsequently a capacitor is formed and located within the capacitor aperture and a via is formed and located within the via apertures. Various combinations of a first capacitor plate layer, a capacitor dielectric layer and a second capacitor plate layer may be contiguous with respect to the capacitor aperture and the via aperture.

    摘要: Transferable probe tips including a metallic probe, a delamination layer covering a portion of the metallic probe, and a bonding alloy, wherein the bonding alloy contacts the metallic probe at a portion of the probe that is not covered by the delamination layer are provided herein. Also, techniques for creating a transferable probe tip are provided, including etching a handler substrate to form one or more via arrays, depositing a delamination layer in each via array, depositing one or more metals in each via array to form a probe tip structure, and depositing a bonding alloy on a portion of the probe tip structure that is not covered by the delamination layer. Additionally, techniques for transferring transferable probe tips are provided, including removing a handler substrate from a probe tip structure, and transferring the probe tip structure via flip-chip joining the probe tip structure to a target probe head substrate.

    摘要: A process and structure for enabling the creation of reliable electrical through-via connections in a semiconductor substrate and a process for filling vias. Problems associated with under etch, over etch and flaring of deep Si RIE etched through-vias are mitigated, thereby vastly improving the integrity of the insulation and metallization layers used to convert the through-vias into highly conductive pathways across the Si wafer thickness. By using an insulating collar structure in the substrate in one case and by filling the via in accordance with the invention in another case, whole wafer yield of electrically conductive through vias is greatly enhanced.
