  • Publication number: 20210193658
    Abstract: An integrated device includes a deep plug. The deep plug is formed by a deep trench extending in a semiconductor body from a shallow surface of a shallow trench isolation. A trench contact makes contact with a conductive filler of the deep trench through the shallow trench at its shallow surface. A system includes at least one integrated device with the deep plug. Moreover, a corresponding process for manufacturing this integrated device includes steps for forming and filling the deep trench before forming the shallow trench isolation and trench window through which the trench contact extends to make contact with the conductive filler. The semiconductor body has a thickness, and the deep trench extends into the semiconductor body less than the thickness.

  • Publication number: 20210143286
    Abstract: A semiconductor body includes a front side and a back side and is configured to support an electronic circuit. A buried region is provided in the semiconductor body at a location between the electronic circuit and the back side. The buried region includes a layer of conductive material and a dielectric layer, where the dielectric layer is arranged between the layer of conductive material and the semiconductor body. A conductive path extends between the buried region and the front side to form a path for electrical access to the layer of conductive material. A capacitor is thus formed with the layer of conductive material providing a capacitor plate and the dielectric layer providing the capacitor dielectric. A further capacitor plate is provided by the semiconductor body, or by a further layer of conductive material in the buried region.

  • Patent number: 8871594
    Abstract: According to a process for manufacturing an integrated power device, projections and depressions are formed in a semiconductor body that extend in a first direction and are arranged alternated in succession in a second direction, transversely to the first direction. Further provided are a first conduction region and a second conduction region. The first conduction region and the second conduction region define a current flow direction parallel to the first direction, along the projections and the depressions. To form the projections and the depressions, portions of the semiconductor body that extend in the first direction and correspond to the depressions, are selectively oxidized.
