Abstract

A semiconductor structure. The semiconductor structure includes: a substrate having a metal wiring level within the substrate; a capping layer on and above a top surface of the substrate; an insulative layer on and above a top surface of the capping layer; an inductor comprising a first portion in and above the insulative layer and a second portion only above the insulative layer; and a wire bond pad within the insulative layer, wherein the first portion the inductor has a height in a first direction greater than a height of the wire bond pad in the first direction, wherein the first direction is perpendicularly directed from the top surface of substrate toward the insulative layer.
