Semiconductor Device and Method of Integrating RF Antenna Interposer with Semiconductor Package

Abstract

A semiconductor device has a substrate and a first electrical component disposed over a first surface of the substrate. An RF antenna interposer is disposed over the substrate with the first electrical component connected to a first antenna disposed on a surface of the antenna interposer. An area of the antenna interposer is substantially the same as an area of the substrate. The first antenna disposed on the surface of the antenna interposer has a plurality of islands of conductive material. Alternatively, the first antenna disposed on the surface of the antenna interposer has a spiral shape of conductive material. A second antenna can be disposed on the surface of the antenna interposer connected to a second electrical component disposed over the substrate. A second electrical component can be disposed over a second surface of the substrate opposite the first surface of the substrate.
