Patent ID: 6967411

Claim:
A multi-layer module comprised of: a first layer comprised of: a first BGA package with a first I/O terminal; and a first interpose layer having a first electrically conductive trace disposed thereon and in electrical connection with said first I/O terminal, wherein said first BGA package and said first interposer layer each have a lateral surface substantially coplanar with an access plane, and said first conductive trace terminates at said access plane to define a first access lead; a second layer bonded to said first layer, said second layer comprised of: a second BGA package with a second I/O terminal; and a second interposer layer having a second electrically conductive trace disposed thereon and in electrical connection with said second I/O terminal, wherein said second BGA package and said second interposer layer each have a lateral surface substantially coplanar with said access plane, and said second conductive trace terminates at said access plane to define a second access lead; and a metalized conductive trace disposed upon said lateral surfaces of said first and second BGA packages and of said first and second interposer layers, wherein said metalized conductive trace electrically connects said first access lead and said second access lead.
