Patent ID: 6876066

Claim:
A method of assembling a stacked microelectronic device assembly, comprising: assembling a plurality of microelectronic device assemblies, each microelectronic device assembly being assembled by: releasably attaching a support to a lead frame, the lead frame having a front surface, a back surface, a thickness, an opening passing through the thickness, and a plurality of lead fingers, the support having an exposed surface spanning the opening; releasably attaching a back surface of a microelectronic device to the exposed surface of the support; electrically coupling the microelectronic device to the lead frame; delivering an encapsulant to a cavity defined by the support, the microelectronic device, and a peripheral dam carried by the lead frame, the encapsulant bonding the microelectronic device to the lead frame; removing the support, leaving the back surface of the microelectronic device exposed; and cutting the lead frame to separate a plurality of electrically isolated lead fingers from the peripheral dam; electrically coupling a first one of the microelectronic device assemblies to a substrate; electrically coupling the lead fingers of a second one of the microelectronic device assemblies to the lead fingers of the first microelectronic device assembly with a back surface of the lead fingers of the second microelectronic device assembly being coupled to a front surface of the lead fingers of the first microelectronic device assembly, defining a gap between the exposed back surface of the microelectronic device of the second microelectronic device assembly and a front surface of the first microelectronic device assembly; and applying an electrically insulative covering over a front surface of the lead fingers of the second microelectronic device assembly.
