Abstract

A microelectronic package includes a lower unit having a lower unit substrate with conductive features and a top and bottom surface. The lower unit includes one or more lower unit chips overly/ing the top surface of the lower unit substrate that are electrically connected to the conductive features of the lower unit substrate. The microelectronic package also includes an upper unit including an upper unit substrate having conductive features, top and bottom surfaces and a hole extending between such top and bottom surfaces. The upper unit further includes one or more upper unit chips overlying the top surface of the upper unit substrate and electrically connected to the conductive features of the upper unit substrate by connections extending within the hole. The upper unit may include an upper unit encapsulant that covers the connections of the upper unit and the one or more upper unit chips.
