  • Patent number: 6670285
    Abstract: Dielectric compositions comprised of porous polymeric matrices are prepared using nitrogen-containing polymers as pore-generating agents. The compositions are useful in the manufacture of electronic devices such as integrated circuit devices and integrated circuit packaging devices. The dielectric compositions are prepared by admixing a polymeric nitrogenous porogen with a high temperature, thermosetting host polymer in a suitable solvent, heating the admixture to cure the polymer and provide a vitrified matrix, and then decomposing the porogen using heat, radiation, or a chemical reagent effective to degrade the porogen. The highly porous dielectric materials so prepared have an exceptionally low dielectric constant on the order of 2.5 or less, preferably less than about 2.0. Integrated circuit devices and integrated circuit packaging devices manufactured so as to contain the dielectric material of the invention are provided as well.

  • Patent number: 6664648
    Abstract: A method and an apparatus are described for applying an integrated circuit to a carrier element. In which a curable compensating layer of initially paste-like consistency is coated substantially with full coverage onto a lower contact area of the integrated circuit. Whereupon the integrated circuit is joined together, by the compensating layer, with the carrier element after a relative alignment in order then to produce an electrical connection between the integrated circuit and conductor tracks of the carrier element via electrical lines surmounting the thickness of the compensating layer. Whereupon the compensating layer is cured resulting in an increased volume of the compensating layer.

  • Patent number: 6650017
    Abstract: A method for manufacturing a semiconductor device having on a silicon substrate semiconductor elements and aluminum (Al) alloy wiring leads as electrically connected thereto is disclosed. The method includes the steps of forming on the silicon substrate an Al alloy layer containing therein copper (Cu), and forming on the Al alloy layer a titanium nitride (TiN) film with enhanced chemical reactivity by using sputtering techniques while applying thereto a DC power of 5.5 W/cm2 or less. Fabrication of such reactivity-rich TiN film on the Al alloy layer results in a reaction layer of Al and Ti being subdivided into several spaced-apart segments. In this case, the reaction layer hardly serves as any diffusion path; thus, it becomes possible to prevent Cu as contained in the Al alloy layer from attempting to outdiffuse with the reaction layer being as its diffusion path.

  • Patent number: 6639303
    Abstract: To fabricate back side contact pads that are suitable for use in a vertical integrated circuit, vias are made in the face side of a wafer, and dielectric and contact pad metal are deposited into the vias. Then the wafer back side is etched until the metal is exposed. When the etch exposes the insulator at the via bottoms, the insulator is etched slower than the wafer material (e.g. silicon). Therefore, when the dielectric is etched off and the metal is exposed, the dielectric protrudes down from the wafer back side around the exposed metal contact pads, by about 8 &mgr;m in some embodiments. The protruding dielectric portions improve insulation between the wafer and the contact pads when the contact pads are soldered to an underlying circuit. In some embodiments, before the contact pads are soldered, additional dielectric is grown on the wafer back side without covering the contact pads.

  • Patent number: 6624516
    Abstract: A metal layer (7), a metallic compound layer (8) and a metal layer (9) are stacked in this order when viewed from the side of a first copper interconnect line (2) and an interlayer insulating film (5) to constitute a second conductive barrier layer (20). As the material for the metal layers (7) and (9), an element having an atomic weight higher than that of copper such as tungsten (W) or tantalum (Ta) is applicable. A second copper interconnect line (6) is conductively connected to the first copper interconnect line (2) at a contact hole (12) through the second conductive barrier layer (20). As the ratio of the volume of the second copper interconnect line (6) at the region for filling a trench (11) to the volume of the second copper interconnect line (6) at the region for filling the contact hole (12) increases, tensile stress to be concentrated at the contact hole (12) becomes greater. As a result, a void is likely to be generated in the contact hole (12).
