  • Patent number: 9596768
    Abstract: A substrate includes a plurality of vias that are lined with dielectric polymer having a substantially uniform thickness. This substantial uniform thickness provides a lumen within each dielectric-polymer-layer-lined via that is substantially centered within the via. Subsequent deposition of metal into the lumen for each dielectric-polymer-layer-lined via thus provides conductive vias having substantially centered metal conductors.

  • Publication number: 20170005160
    Abstract: Copper (Cu) grain boundaries can move during a thermal cycle resulting in the Cu grain position being offset. Such Cu pumping can disturb the surface of a bottom metal, and can physically break a dielectric of a metal-insulator-metal (MIM) capacitor. By capping the bottom metal with an anchoring cap, Cu pumping is reduced or eliminated.
