  • Publication number: 20080290523
    Abstract: A semiconductor device includes an interconnection layer provided on a substrate, a first insulating film provided on the substrate, and on the interconnection layer so as to coat the interconnection layer, the first insulating film includes a silicon oxide film, a second insulating film provided on the first insulating film, the second insulating film includes either a silicon oxynitride film or a silicon nitride film, and an insulative coating film provided on the second insulating film.

  • Publication number: 20050233580
    Abstract: An alignment pattern comprises at least a sloped surface which communicates between a top surface of an inter-layer insulator extending over a surface of a substrate and a field oxide film selectively formed over the surface of the substrate and a flat surface of a metal plug, and the flat surface being lower in level than the top surface of the inter-layer insulator. The metal plug is buried within an alignment hole which completely penetrates the insulation layer and at least reaches the field oxide film, so that the alignment hole has a bottom level which is deeper than a bottom level of the inter-layer insulator.
