Abstract:
1. A method for manufacturing stacked microelectronic devices, the method comprising: placing an attachment structure on a back side of a first microelectronic die, wherein the attachment structure includes a plurality of openings at least partially aligned with back side portions of electrically conductive through-substrate interconnects in the first die, and wherein the attachment structure further includes a plurality of conductive couplers formed in at least a portion of the openings and electrically coupled to corresponding through-substrate interconnects; after placing the attachment structure on the back side of the first microelectronic die, contacting the attachment structure with a front side of a second microelectronic die; joining the back side of the first die and the front side of the second die, wherein the first die is physically and electrically connected with the second die via the attachment structure; and attaching a back side of the second die to a support member and electrically coupling the second die to the support member before joining the first and second dies.
