Abstract:
A microelectronic package can include a substrate having first and second opposed surfaces, and first and second microelectronic elements having front surfaces facing the first surface. The substrate can have a plurality of substrate contacts at the first surface and a plurality of terminals at the second surface. Each microelectronic element can have a plurality of element contacts at the front surface thereof. The element contacts can be joined with corresponding ones of the substrate contacts. The front surface of the second microelectronic element can partially overlie a rear surface of the first microelectronic element and can be attached thereto. The element contacts of the first microelectronic element can be arranged in an area array and are flip-chip bonded with a first set of the substrate contacts. The element contacts of the second microelectronic element can be joined with a second set of the substrate contacts by conductive masses.
