  • Publication number: 20160056229
    Abstract: The method includes forming a metal interconnection layer and a first interlayer insulating layer on a semiconductor substrate, forming a reservoir capacitor region by etching the first interlayer insulating layer to expose the metal interconnection layer, forming a barrier metal layer on the reservoir capacitor region, forming a sacrificial insulating layer on the barrier metal layer in a lower portion of the reservoir capacitor region, performing a pre-cleaning process to remove the barrier metal layer on a sidewall of the reservoir capacitor region, and removing the sacrificial insulating layer.

  • Publication number: 20140061907
    Abstract: A semiconductor device includes a metal line and a metal pad formed at different integration levels of a semiconductor substrate, and an isolation layer by which the metal line and the metal pad are spaced apart from each other. The semiconductor device prevents short-circuiting between the metal pad and the metal line although the isolation layer is dislocated.
