Abstract
A magnetic field sensor structure includes a magnetoresistive sensor assembly and a transistor assembly. A dielectric layer is deposited on the transistor assembly. The dielectric layer includes a trench that exposes an interconnect of the transistor assembly. A damascene process is performed to form an ultra-thick metal (UTM) layer within the trench to create a first metal coil. The first metal coil is configured as a first reset component. Another dielectric layer is formed on the first metal coil. A flux guide is formed within the another dielectric layer. A second metal coil is formed over the another dielectric layer. The second metal coil is configured as a second reset component. The first reset component and the second reset component are configured as a reset mechanism, which is responsive to the transistor assembly and operable to magnetize the flux guide to a predetermined orientation.
