Patent ID: 8723308

Claim:
A packaged integrated device, comprising: a package substrate; a package lid attached to the package substrate using an adhesive, the package lid and the package substrate defining a package interior, wherein the package lid includes a first conductive layer, a second conductive layer and a core disposed between the first and second conductive layers, wherein the first conductive layer defines a first surface of the package lid facing the package interior, and wherein the second conductive layer defines a second surface of the package lid opposite the first surface, and wherein a portion of the first conductive layer contacts the adhesive; and an integrated device die mounted within the package interior, wherein the first and second conductive layers comprise different materials, wherein the package substrate includes a nonconductive layer and a conductive trace disposed on the nonconductive layer, and wherein the package lid is mounted to portions of both the conductive trace and the nonconductive layer using the adhesive, and wherein the first surface of the package lid includes an interface surface for mounting the package lid to the package substrate using the adhesive, and wherein the conductive trace is patterned to alternately expose portions of the nonconductive layer and the conductive trace to the adhesive around an annular pattern corresponding to the interface surface.
