  • Patent number: 8836040
    Abstract: A semiconductor standard cell includes an N-type diffusion area and a P-type diffusion area, both extending across the cell and also outside of the cell. The cell also includes a conductive gate above each diffusion area to create a semiconductive device. A pair of dummy gates are also above the N-type diffusion area and the P-type diffusion area creating a pair of dummy devices. The pair of dummy gates are disposed at opposite edges of the cell. The cell further includes a first conductive line configured to couple the dummy devices to power for disabling the dummy devices.

  • Publication number: 20140225223
    Abstract: A method of fabricating a metal-insulator-metal (MIM) capacitor reduces the number of masks and processing steps compared to conventional techniques. A conductive redistribution layer (RDL) is patterned on a semiconductor chip. A MIM dielectric layer is deposited over the RDL. A first conductive layer of a MIM capacitor is deposited over the MIM dielectric layer. The MIM dielectric layer is patterned using a MIM conductive layer mask. The conductive redistribution layer includes two RDL nodes that extend under the first conductive layer of the MIM capacitor. A conductive via or bump extends through the MIM dielectric layer and couples one of the RDL nodes to the first conductive layer of the MIM capacitor.
