  • Publication number: 20060289974
    Abstract: A packaged integrated circuit which includes a die 700 having a surface and corners separated by edges. The die surface includes depressions 600, 720 so that mold compound 114 covering the die surface fills the depressions. The filling of the depressions in the die surface enhances the adhesion of the mold compound to the die. The die can include bond pads 714, in which case the depressions can take the form of slots 720 in the bond pads. In addition, the depressions can take the form of trenches 600 at the surface of the die in a dielectric layer 703. The trenches can be at the die corners and along the die edges.

  • Publication number: 20040009640
    Abstract: The invention describes a high capacitance damascene capacitor. A etch-stop/capacitor dielectric layer 60 is sandwiched between two conductive plates 40 and 75 to form an integrated circuit capacitor. One metal plate 40 is copper formed using a damascene process. The high capacitance of the structure is due to the thin high k dielectric material used to form the etch-stop/capacitor dielectric layer 60.

  • Patent number: 6443743
    Abstract: A method of forming an electrical interconnect through a via to electrically couple two electrically conductive layers and the device. There are provided a pair of electrically conductive layers and an electrically insulating layer between the pair of electrically conductive layers having a via extending between the pair of electrically conductive layers. A layer of titanium is formed covering the walls of the via and extending onto one of the pair of electrically conductive layers. A thin layer of titanium nitride with a poor step ?? technique is formed covering the titanium on the walls but not covering the titanium on the one of the pair of electrically conductive layers. The remainder of the via is filled with aluminum. The layer of titanium and the layer of titanium nitride preferably extend out of the via and between the electrically insulating layer and at least one of the pair of electrically conductive layers.
