The present disclosure describes a structure with passivation layers with rounded corners and a method for forming such a structure. The method includes forming a first insulating layer on a substrate, where the substrate includes a first conductive structure. The method further includes forming an opening in the first insulating layer to expose the first conductive structure and forming a second conductive structure on the first insulating layer, where the second conductive structure is in contact with the first conductive structure through the opening. The method further includes removing a portion of the second conductive structure with a first etching condition, removing a portion of the first insulating layer with a second etching condition, different from the first etching condition, to form a rounded corner between a sidewall of the second conductive structure and a top surface of the first insulating layer, and depositing a second insulating layer on the first insulating layer and the second conductive structure.

A method is provided for producing a semiconductor structure including at least one capacitor. The method includes: forming a first metal layer; forming a second metal layer; forming a third high resistance (HiR) layer interposed between the first metal layer and the second metal layer, wherein at least one of the first metal layer and the sconed metal layer at least partially overlap with the third HiR layer; and defining at least one of a first capacitor between the first metal layer and the third HiR layer and a second capacitor between the second metal layer and the third HiR layer. Suitably, the method is carried out subsequent to a front-end-of-line (FEOL) portion of a semiconductor fabrication process.
