Abstract
A shielding arrangement for protecting a circuit containing magnetically sensitive materials from external stray magnetic fields. A shield of a material having a relatively high permeability is formed over the magnetically sensitive materials using thin film deposition techniques. Alternatively, a planar shield is affixed directly to a surface of semiconductor die containing an integrated circuit structure.
