  • Patent number: 7598137
    Abstract: A semiconductor device including a metal-insulator-metal (MIM) capacitor is manufactured such that a via for connecting upper and lower conductive layers is formed through an insulating interlayer after a silicon nitride layer is deposited as a thick layer on the insulating interlayer. This protects an edge of a MIM structure during an etching process that forms the via. In addition, a fluorine gas can be used in a gas stripping process to remove a polymer residue when stripping the photoresist used to form the via. The MIM capacitor has an insulator layer. The method of manufacturing the device includes forming an insulator layer of the MIM capacitor to a predetermined thickness on the insulating interlayer. The predetermined thickness is equal to the desired thickness plus an augmentation thickness, and the augmentation thickness is determined according to the stripping process for removing the photoresist pattern.

  • Patent number: 7442626
    Abstract: A repair fuse element and method of construction are disclosed that eliminate or substantially reduce the disadvantages and problems associated with prior fuse elements. In one embodiment, the fuse element is constructed with a rectangular-shaped contact. The contact is made long enough so that it makes contact at each end with a metal layer, but design rule spacing is still maintained between the connections with the metal layer. The overlapping areas between the rectangular contact and the metal layers are asymmetrical. Alternatively, these overlapping areas are smaller than the design rule overlap requirements. In a second embodiment, a fuse element is constructed with a plurality of rectangular-shaped contacts. As a result, a current value that is significantly lower than conventional fuse current values, can be used to melt such a contact or blow the fuse.
