Packaged devices with multiple planes of embedded electronic devices

Abstract

A packaged semiconductor structure includes an interconnect layer and a first microelectronic device on a first major surface of the interconnect layer. The structure also includes a substrate having a cavity, wherein the cavity is defined by a vertical portion and a horizontal portion, wherein the vertical portion surrounds the first device, the horizontal portion is over the first device, and the first device is between the horizontal portion and the first major surface of the interconnect layer such that the first device is in the cavity. The structure further includes a second microelectronic device attached to the horizontal portion of the substrate, and encapsulant on the interconnect layer and surrounding the first device, the substrate, and the second device, such that the substrate is embedded in the encapsulant.
