Abstract

In one aspect, a method includes forming a metal layer on a substrate, wherein the metal layer comprises a first coil, forming a planarized insulator layer on the metal layer, forming at least one via in the planarized insulator layer, depositing a magnetoresistance (MR) element on the planarized insulator layer, and forming a second coil extending above the MR element. The at least one via electrically connects to the metal layer on one end and to MR element on the other end.
