Abstract:
A microelectronic package includes a subassembly including a first substrate and first and second microelectronic elements having contact-bearing faces facing towards oppositely-facing first and second surfaces of the first substrate and each having contacts electrically connected with the first substrate. The contact-bearing faces of the first and second microelectronic elements at least partially overlie one another. Leads electrically connect the subassembly with a second substrate, at least portions of the leads being aligned with an aperture in the second substrate. The leads can include wire bonds extending through an aperture in the first substrate and joined to contacts of the first microelectronic element aligned with the first substrate aperture. In one example, the subassembly can be electrically connected with the second substrate using electrically conductive spacer elements.
