Abstract
A microelectronic device, possibly a packaged microelectronic device, contains a magnetic sensor component and magnetizable structural features. Magnetic moments of the magnetizable structural features are aligned parallel to each other. The microelectronic device is formed by applying a magnetic field so as to align magnetic moments of the magnetizable structural features with the applied magnetic field. Application of the magnetic field is subsequently discontinued. The magnetic moments of the magnetizable structural features remain aligned parallel to each other after the applied magnetic field is discontinued.

A microelectronic device, comprising:
- a substrate;
- a magnetic sensor component;
- and
- magnetizable structural features containing magnetizable material, separate from the magnetic sensor component, each magnetizable structural feature having a magnetic moment, wherein the magnetic moments of the magnetizable structural features are aligned parallel to each other.
A packaged microelectronic device, comprising:
- an active circuit;
- a magnetic sensor component;
- a package housing the active circuit and the magnetic sensor component;
- and
- magnetizable structural features disposed in the package, separate from the magnetic sensor component, wherein the magnetizable structural features of the package contain magnetizable material, each magnetizable structural feature having a magnetic moment, wherein the magnetic moments of the magnetizable structural features are aligned parallel to each other.
