Micromagnetic device and method of forming the same
First Claim
1. A micromagnetic device formed on a substrate, comprising:
- a first insulating layer formed in a trench of said substrate;
a first seed layer formed above said first insulating layer;
a first magnetic core layer selectively formed above said first seed layer and with at least a portion formed directly above said trench; and
a second insulating layer formed above said first magnetic core layer.

Abstract
A micromagnetic device includes a first insulating layer formed above a substrate, a first seed layer formed above the first insulating layer, a first conductive winding layer selectively formed above the first seed layer, and a second insulating layer formed above the first conductive winding layer. The micromagnetic device also includes a first magnetic core layer formed above the second insulating layer, a third insulating layer formed above the first magnetic core layer, and a second magnetic core layer formed above the third insulating layer. The micromagnetic device still further includes a fourth insulating layer formed above the second magnetic core layer, a second seed layer formed above the fourth insulating layer, and a second conductive winding layer formed above the second seed layer and in vias to the first conductive winding layer. The first and second conductive winding layers form a winding for the micromagnetic device.
