Patent ID: 7598596

Claim:
A shield structure for shielding an electromagnetic-field-susceptible region of a semiconductor component located on a substrate that has a top surface and a bottom surface, the structure comprising: a first shield structure formed over the semiconductor component and the top surface of the substrate, wherein the first shield structure includes a first stress-relief layer electrodeposited over the semiconductor component in a shield region substantially corresponding to the electromagnetic-field-susceptible region, wherein the first stress-relief layer has a first stress condition, and a first magnetic shield layer electrodeposited over the stress-relief layer and mechanically coupled to the first stress-relief layer within the shield region, wherein the first magnetic shield layer has a second stress condition that is substantially opposite of the first stress condition, wherein sides of the first stress-relief layer and sides of the first magnetic shield layer define a perimeter of the shield region; a leadframe; and a second shield structure formed on the leadframe, wherein the second shield structure includes a second stress-relief layer formed under the semiconductor component, wherein the second stress-relief layer has the first stress condition, and a second magnetic shield layer mechanically coupled to the second stress-relief layer, wherein the second magnetic shield layer has the second stress condition, and wherein the bottom surface of the substrate is mounted on the second shield structure.
