  • Patent number: 8426308
    Abstract: A method of forming through silicon vias (TSVs) includes forming a primary via hole in a semiconductor substrate, depositing low-k dielectric material in the primary via hole, forming a secondary via hole by etching the low-k dielectric in the primary via hole, in such a manner that a via insulating layer and an inter metal dielectric layer of the low-k dielectric layer are simultaneously formed. The via insulating layer is formed of the low-k dielectric material on sidewalls and a bottom surface of the substrate which delimit the primary via hole and the inter metal dielectric layer is formed on an upper surface of the substrate. Then a metal layer is formed on the substrate including in the secondary via hole, and the metal layer is selectively removed from an upper surface of the semiconductor substrate.

  • Patent number: 8404579
    Abstract: A fuse base insulating region, for example, an insulating interlayer or a compensation region disposed in an insulating interlayer, is formed on a substrate. An etch stop layer is formed on the fuse base insulating region and forming an insulating interlayer having a lower dielectric constant than the first fuse base insulating region on the etch stop layer.

  • Publication number: 20110263117
    Abstract: A method of manufacturing a semiconductor device and an apparatus for manufacturing a semiconductor device in which moisture is removed from a porous low-dielectric layer after a chemical mechanical polishing (CMP) process include formation of a porous low-dielectric layer on a substrate. A metal interconnection is formed on the substrate having the porous low-dielectric layer. The metal interconnection forms a planar surface with the porous low-dielectric layer to fill the openings. Ultraviolet (UV) light is irradiated to the porous low-dielectric layer to remove absorbed moisture from the porous low-dielectric layer. A capping layer is formed on the substrate having the porous low-dielectric layer and the metal interconnection. The capping layer is formed in-situ to prevent additional absorption of moisture.
