    Abstract: A dual damascene process for forming conductive interconnects on an integrated circuit die. The process includes providing a layer (16) of porous, ultra low-k (ULK) dielectric material in which a via opening (30) is subsequently formed. A thermally degradable polymeric (“porogen”) material (42) is applied to the side wall sidewalls of the opening (30) such that the porogen material penetrates deeply into the porous ULK dielectric material (thereby sealing the pores and increasing the density thereof). Once a conductive material (36) has been provided with the opening (30) and polished back by means of chemical mechanical polishing (CMP), the complete structure is subjected to a curing step to cause the porogen material (44) with the ULK dielectric layer (16) to decompose and evaporate, thereby restoring the porosity (and low-k value) of the dielectric layer (16). Attached are a marked-up copy of the originally filed specification and a clean substitute specification in accordance with 37 C.F.R. §§1.

A lower level metal interconnect structure comprises a first dielectric material layer and a copper-containing structure embedded in a lower metallic liner. After a planarization process that forms the copper-containing structure, a material that forms Cu—S bonds with exposed surfaces of the copper-containing structure is applied to the surface of the copper-containing structure. The material is selectively deposited only on exposed Cu surfaces, thereby forming a self-aligned copper encapsulation layer, and provides a high adhesion strength to the copper surface underneath. A dielectric cap layer and an upper level metal interconnect structure can be subsequently formed on the copper encapsulation layer.

    Abstract: A chip package structure comprises a carrier, a chip and an underfill. The chip has an active surface on which a plurality of bumps is formed. The chip is flip-chip bonded onto the carrier with the active surface facing the carrier, and is electrically connected to the carrier through the bumps. The underfill is filled between the chip and the carrier. A portion of the underfill near the chip serves as a first underfill portion. The portion of the underfill near the carrier serves as a second underfill portion. The Young's modulus of the first underfill portion is smaller than the Young's modulus of the second underfill portion. The second underfill portion can be optionally replaced with a selected encapsulation. The selected encapsulation covers the chip and the carrier around the chip.

  • Patent number: 7608910
    Abstract: A semiconductor device and methods for protecting a semiconductor device. In an example, the semiconductor device may include a semiconductor substrate including at least one electrostatic discharge (ESD) protection device, at least one metal interconnection line connected to the at least one ESD protection device through a conductive plug and a passivation layer disposed on less than all of the metal interconnection line. In an example method, a semiconductor device may be protected by diverting at least a portion of an electron build-up from an accumulation point to one or more protective circuits along one or more conductive paths, the electron build-up, without the diverting, sufficient to cause an ESD at the accumulation point. In another example, a semiconductor device may be protected by exposing one or more conductive lines to a fuse opening to avoid an ESD by diverting an electron build-up at the fuse opening to one or more ESD protection devices.

  • Patent number: 7416923
    Abstract: An underfill film for an electronic device includes a thermally conductive sheet. The electronic device may include a printed circuit board, an electrical component, an underfill, and the thermally conductive sheet. The underfill is situated between the circuit board and the component. The thermally conductive sheet is situated within the underfill, and together with the underfill, constitutes the underfill film. The device may include solder bumps affixing the component to the circuit board, the underfill film having holes within which the solder bumps are aligned. There may be solder bumps on the underside of the circuit board promoting heat dissipation. There may be heat sinks on the circuit board to which the thermally conductive sheet is affixed promoting heat dissipation. The thermally conductive sheet may be affixed to a chassis promoting heat dissipation. The thermally conductive sheet thus promotes heat dissipation from the component to at least the circuit board.

  • Patent number: 7382037
    Abstract: The invention is directed to improvement of reliability of a semiconductor device having penetrating electrodes by preventing a protection film and an insulation film peeling. A peeling prevention layer for preventing an insulation film and a protection layer peeling is formed in corner portions of the semiconductor device. The peeling prevention layer can increase its peeling prevention effect more when formed in a vacant space of the semiconductor device other than the corner portions, for example, between ball-shaped conductive terminals. In a cross section of the semiconductor device, the peeling prevention layer is formed on the insulation film on the back surface of the semiconductor substrate, and the protection layer formed of a solder resist or the like is formed covering the insulation film and the peeling prevention layer. The peeling prevention layer has a lamination structure of a barrier seed layer and a copper layer formed thereon when formed by an electrolytic plating method.
