Abstract
A magnetoresistive sensing device includes a substrate, a magnetoresistive sensing element, a circuitry element and a shielding unit. The magnetoresistive sensing element, the circuitry element and the shielding unit are disposed at the same side of the substrate. The shielding unit is between the magnetoresistive sensing element and the circuitry element. The shielding unit comprises at least one magnetic material.
