ABSTRACT:
A magnetic shielding device is provided for protecting at least one magnetically sensitive component on a substrate according to embodiments of the present invention. The device comprises a first shield having a top portion, and one or more side portions, wherein the top and side portions along with the substrate encloses the magnetic sensitive component within for protecting the same from an external magnetic field, and wherein the magnetic shielding device contains at least two magnetic shielding materials with one having a relatively higher magnetic permeability property but lower magnetic saturation property while the other having a relatively lower magnetic permeability property but higher magnetic saturation property.
