Structure and method for inductor with windings having different widths

A structure comprising:

• a magnetic core extending a length over a substrate and within a pair of wiring layers of a device;
• and
• an inductor over the substrate and including a plurality of windings coupled together in series about the magnetic core, each winding having a first segment within a first wiring layer coupled to a second segment within a second wiring layer, the first segment and second segment defining a substantial V-shape, wherein the plurality of windings includes:
• a first winding having a first width along a same direction as the length of the magnetic core, and
• a second winding having a second width along the same direction as the length of the magnetic core, wherein the second width is larger than the first width.

A method comprising:

• providing an inductor including a plurality of windings about a magnetic core, each winding having a first segment within a first wiring layer coupled to a second segment within a second wiring layer, wherein the plurality of windings includes:
• a first winding having a first width along a same direction as a length of the magnetic core, and
• a second winding having a second width along the same direction as the length of the magnetic core, wherein the second width is larger than the first width;
• and
• transmitting a current through the inductor to induce a magnetic flux within the magnetic core, wherein a flux density in a first portion of the magnetic core within the first winding is greater than a flux density in a second portion of the magnetic core within the second winding.
