Claim:
1. A method of forming a microelectronic device package comprising: forming a stand-off material layer on a carrier; forming an opening through the stand-off material layer to expose a portion of the carrier; forming a sacrificial material layer on the stand-off material layer and within the stand-off material layer opening; forming an opening through the sacrificial material layer to expose a portion of the stand-off material layer and a portion of the carrier; attaching a microelectronic device to the carrier, wherein the microelectronic device has an active surface, an opposing back surface, and a thickness defined by the distance between the microelectronic device active surface and the microelectronic device back surface; attaching at least one secondary device to the at least one stand-off material layer, wherein the at least one secondary device is position within the thickness of the microelectronic device; disposing a dielectric layer over the microelectronic device and the at least one secondary device; forming an electrically conductive path between the at least one secondary device pad and the microelectronic device; and removing the at least one stand-off.
