    摘要: Methods of forming and assemblies having hybrid interconnection grid arrays composed of a homogenous mixture of Pb-free solder joints and Pb-containing solder paste on corresponding sites of a printed board. The aligned Pb-free solder joints and Pb-containing solders are heated to a temperature above a melting point of the Pb-free solder joint for a sufficient time to allow complete melting of both the Pb-free solder joints and Pb-containing solder paste and the homogenous mixing thereof during assembly. These molten materials mix together such that the Pb from the Pb-containing solder disperses throughout substantially the entire Pb-free solder joint for complete homogenization of the molten materials to form the homogenous hybrid interconnect structures of the invention.

    摘要: Methods of blocking ionizing radiation to reduce soft errors and resulting IC chips are disclosed. One embodiment includes forming a front end of line (FEOL) for an integrated circuit (IC) chip; and forming at least one back end of line (BEOL) dielectric layer including ionizing radiation blocking material therein. Another embodiment includes forming a front end of line (FEOL) for an integrated circuit (IC) chip; and forming an ionizing radiation blocking layer positioned in a back end of line (BEOL) of the IC chip. The ionizing radiation blocking material or layer absorbs ionizing radiation and reduces soft errors within the IC chip.

    摘要: A dielectric material layer is deposited on exposed surfaces of a bonded structure that includes a first substrate and a second substrate. The dielectric material layer is formed on an exposed planar surface of a second substrate and the entirety of peripheral sidewalls of the first and second substrates. The dielectric material layer can be formed by chemical vapor deposition, atomic layer deposition, or plasma induced deposition. Further, the dielectric material layer seals the entire periphery of the interface between the first and second substrates. If a planar portion of the dielectric material layer can be removed by planarization to facilitate thinning of the bonded structure, the remaining portion of the dielectric material layer can form a dielectric ring.
