摘要： An interposer sandwich structure includes a top interposer and a bottom interposer enclosing an integrated circuit electronic device that includes an attachment for attaching the device to the bottom interposer, and an interconnection structure connecting the top interposer to the bottom interposer. The top interposer may also be directly connected to a chip carrier in addition to the bottom interposer. The structure provides shielding and protection of the device against Electrostatic Discharge (ESD), Electromagnetic Interference (EMI), and Electromagnetic Conductivity (EMC) in miniaturized 3D packaging.
