Abstract

Official abstract text for this publication.

An integrated circuit package may comprise a multilayer frame package including: a bottom layer; and a magnetic shield layer, including a sub-frame and a magnetic shield disposed within a periphery of the sub-frame; and an integrated circuit die provided on or above the magnetic shield layer of the multilayer frame package.

First claim

Opening claim text (preview).

What is claimed is: 1 . An integrated circuit package comprising: a multilayer frame package including: a bottom layer; and a magnetic shield layer, including a sub-frame and a magnetic shield disposed within a periphery of the sub-frame; and an integrated circuit die provided on or above the magnetic shield layer of the multilayer frame package. 2 . The integrated circuit package of claim 1 , wherein the bottom layer and the sub-frame are made of the same material. 3 . The integrated circuit package of claim 1 , further comprising interconnects routed through the bottom layer and the sub-frame. 4 . The integrated circuit package of claim 1 , wherein the magnetic shield includes a film or a foil, wherein the film or foil includes a thickness between 50 and 150 micrometers. 5 . The integrated circuit package of claim 1 , wherein the magnetic shield is fixed to an inner perimeter of the sub-frame. 6 . The integrated circuit package of claim 1 , wherein the magnetic shield is fixed to an inner perimeter of the sub-frame, and wherein the inner perimeter of the sub-frame is rectangular-shaped. 7 . The integrated circuit package of claim 1 , wherein the magnetic shield is fixed to an inner perimeter of the sub-frame, and wherein the inner perimeter of the sub-frame is oval-shaped. 8 . The integrated circuit package of claim 1 , wherein the multilayer frame package includes a plurality of magnetic shields. 9 . The integrated circuit package of claim 8 , wherein the multilayer frame package includes a plurality of magnetic shield layers, wherein each of the plurality of magnetic shield layers includes a sub-frame and a magnetic shield. 10 . The integrated circuit package of claim 1 , wherein a width of the magnetic shield is similar to a width of an active area of the integrated circuit die. 11 . The integrated circuit package of claim 1 , wherein the integrated circuit die includes a magnetoresistive device. 12 . A multilayer frame package including: a bottom layer; and a magnetic shield layer, including a sub-frame and a magnetic shield disposed within a periphery of the sub-frame. 13 . The multilayer frame package of claim 12 , wherein the bottom layer and the sub-frame are made of the same material. 14 . The multilayer frame package of claim 12 , further comprising interconnects routed through the bottom layer and the sub-frame. 15 . The multilayer frame package of claim 12 , wherein the magnetic shield includes a film or a foil, wherein the film or foil includes a thickness of approximately 50 to approximately 150 micrometers. 16 . The multilayer frame package of claim 12 , wherein the magnetic shield is fixed to an inner perimeter of the sub-frame. 17 . The multilayer frame package of claim 12 , wherein the magnetic shield is fixed to an inner perimeter of the sub-frame, and wherein the inner perimeter of the sub-frame is rectangular-shaped. 18 . The multilayer frame package of claim 12 , wherein the multilayer frame package includes a plurality of magnetic shields. 19 . The multilayer frame package of claim 18 , wherein the multilayer frame package includes a plurality of magnetic shield layers, wherein each of the plurality of magnetic shield layers includes a sub-frame and a magnetic shield. 20 . The multilayer frame package of claim 12 , wherein the multilayer frame package further includes: a top layer, wherein the sub-frame is disposed in between the bottom layer and the top layer
