  • Publication number: 20240120301
    Abstract: A back end of line (BEOL) structure for an integrated circuit chip includes a last metal structure providing a bonding pad. A passivation structure over the bonding pad includes a first opening extending exposing an upper surface of the bonding pad. A conformal nitride layer extends over the passivation structure and is placed in contact with the upper surface of the bonding pad. An insulator material layer covers the conformal nitride layer and includes a second opening that extends through both the insulator material layer and the conformal nitride layer. A foot portion of the conformal nitride layer on the upper surface of the bonding pad is self-aligned with the second opening.

  • Publication number: 20220384585
    Abstract: An integrated electronic circuit including: a dielectric body delimited by a front surface; A top conductive region of an integrated electronic circuit extend within a dielectric body having a front surface. A passivation structure including a bottom portion and a top portion laterally delimits an opening. The bottom portion extends on the front surface, and the top portion extends on the bottom portion. A field plate includes an internal portion and an external portion. The internal portion is located within the opening and extends on the top portion of the passivation structure. The external portion extends laterally with respect to the top portion of the passivation structure and contacts at a bottom one of: the dielectric body or the bottom portion of the passivation structure. The opening and the external portion are arranged on opposite sides of the top portion of the passivation structure.

  • Patent number: 10199370
    Abstract: A method of manufacturing an electronic device for providing galvanic isolation includes forming a dielectric layer on a semiconductor body and integrating, in the dielectric layer, a galvanic isolation module, the integrating including forming a first metal region at a first height of the dielectric layer. A second metal region is formed at a second height greater than the first height of the dielectric layer, the first and second metal regions being at least one of capacitively and magnetically coupleable together. Forming the second metal region includes etching selective portions of the dielectric layer to form at least one trench having a side wall coupled to a bottom wall through rounded surface portions, and filling each trench with metal material to form the second metal region having rounded edges.

  • Publication number: 20180097055
    Abstract: A dielectric structure extends over the substrate and a transformer is integrated in the dielectric structure. The transformed includes a first winding in the dielectric layer at a first height and a second winding in the dielectric layer at a second height greater than the first height. The first and second windings are magnetically coupleable to one another. A magnetic element is positioned in alignment with the first and second windings. In one implementation, the magnetic element underlies the first winding in a position between the substrate and the first winding. In another implementation, the magnetic element overlies the second winding.
