Semiconductor Device Having Electrical Devices Mounted to IPD Structure and Method of Shielding Electromagnetic Interference

摘要

A semiconductor device has an IPD structure formed over a substrate. First and second electrical devices are mounted to a first surface of the IPD structure. An encapsulant is deposited over the first and second electrical devices and IPD structure. A shielding layer is formed over the encapsulant and electrically connected to a conductive channel in the IPD structure. The conductive channel is connected to ground potential to isolate the first and second electrical devices from external interference. A recess can be formed in the encapsulant material between the first and second electrical devices. The shielding layer extends into the recess. An interconnect structure is formed on a second surface of the IPD structure. The interconnect structure is electrically connected to the first and second electrical devices and IPD structure. A shielding cage can be formed over the first electrical device prior to depositing encapsulant.
