1. A process of forming an electronic device comprising:
- forming an interconnect level overlying a die substrate, wherein the interconnect level comprises a first interconnect and a second interconnect;
forming a shock-absorbing layer overlying the interconnect level;
patterning the shock-absorbing layer to define a first opening that exposes the first interconnect and a second opening that exposes the second interconnect;
forming conductive traces, wherein;
the conductive traces include a first conductive trace and a second conductive trace;
a via portion of the first conductive trace extends to the first opening of the shock-absorbing layer and is electrically connected to the first interconnect, and a primary pad portion of the first conductive trace overlies the shock-absorbing layer; and
a secondary pad portion of the second conductive trace overlies the shock-absorbing layer, and a via portion of the second conductive trace extends to the second opening of the shock-absorbing layer and is electrically connected to the second interconnect; and
attaching at least one wire to the conductive traces to form an inductor, wherein;
a first wire of the at least one wire is attached to the primary pad portion of the first conductive trace; and
the first wire or a second wire of the at least one wire is attached to the secondary pad portion of the second conductive trace.

Abstract
An electronic device can include an inductor overlying a shock-absorbing layer. In one aspect, the electronic device can include a substrate, an interconnect level overlying the substrate, and the shock-absorbing layer overlying the interconnect level. The inductor can include conductive traces and looped wires. The conductive traces can be attached to the conductive traces over the shock-absorbing layer. In another aspect, a process can be used to form the electronic device including the inductor. In still another aspect, an electronic device can a toroidal-shaped inductor that includes linear inductor segments that are connected in series.
