  • Patent number: 11574996
    Abstract: In various embodiments, the present disclosure provides capacitors and methods of forming capacitors. In one embodiment, a capacitor includes a substrate, a first electrode on the substrate, a second electrode, and a first dielectric layer. A portion of the first electrode is exposed in a contact region. The first dielectric layer includes a first dielectric region between the first electrode and the second electrode, and a second dielectric region between the first dielectric region and the contact region. The second dielectric region is contiguous to the first dielectric region, and a surface of the second dielectric region defines a surface path between the first electrode and the contact region. The second dielectric region has a plurality of grooves that increase a spatial extension of said surface path.

  • Patent number: 6465857
    Abstract: A chip of semiconductor material includes a first layer with a first type of conductivity having a surface on the first major surface of the chip, a second layer with the first type of conductivity having a surface on the second major surface of the chip, and a third layer with the first type of conductivity having a resistivity lower than those of the first and second layers and disposed between the first layer and the second layer. A first region with a second, type of conductivity, extends from the first surface into the first layer, and a second region with the second type of conductivity, extends from the second major surface into the second layer. First, second and third electrical connections are provided for connection with the first region, the second region, and the third layer, respectively.
