Patent ID: 7255801

Claim:
A method for the creation of a suspended inductor, comprising the steps of: providing a substrate; depositing a layer of dielectric over the surface of said substrate; depositing a layer of etch stop material over the surface of said layer of dielectric; patterning and etching said layer of etch stop material, thereby creating a pattern of said inductor through the layer of etch stop material; etching said layer of dielectric to a measurable depth in accordance with said pattern created through said layer of etch stop material, creating a pattern for said inductor in said layer of dielectric; filling said pattern created in said layer of dielectric with an inductor material to a measurable height; exposing the surface area of said layer of dielectric; and etching the exposed surface area of said layer of dielectric, thereby creating an air gap in said layer of dielectric, said air gap contiguous with said inductor material.
