Patent ID: 8507318

Claim:
A method for manufacturing a microelectronic device, comprising: attaching a first microelectronic die to a first interposer substrate; coupling a second interposer substrate to the first microelectronic die with the microelectronic die positioned between the first and second interposer substrates; electrically coupling the first microelectronic die to the first interposer substrate; wire-bonding the second interposer substrate to the first interposer substrate; encapsulating a perimeter portion of the second interposer substrate such that at least one pad on the second interposer substrate remains exposed; attaching a second microelectronic die to a third interposer substrate; coupling a fourth interposer substrate to the second microelectronic die positioned between the third and fourth interposer substrates; and stacking the second microelectronic device on top of the first microelectronic device with a plurality of electrical couplers positioned between the first and second microelectronic devices.
