Patent ID: 8299626

Claim:
A microelectronic package comprising: a first microelectronic element having a plurality of contacts; a second microelectronic element having a plurality of contacts, said second microelectronic element disposed under said first microelectronic element, such that said contacts of said first microelectronic element are exposed beyond an edge of said second microelectronic element; a dielectric element disposed under said second microelectronic element, said dielectric element having a first face, a second face remote from said first face, conductive features including contact pads exposed at said second face, and a hole extending from said first face to said second face; a first set of electrically conductive connection elements extending between said plurality of contacts of said first microelectronic element and at least some of said conductive features of said dielectric element; and a second set of electrically conductive connection elements extending between said plurality of contacts of said second microelectronic element and at least some of said conductive features of said dielectric element; wherein at least some of said first set of electrically conductive connection elements and at least some of said second set of electrically conductive connection elements extend through said hole of said dielectric element and are connected to said contact pads, wherein an encapsulant is disposed over said first and second microelectronic elements and said first and second sets of electrically conductive connection elements, and wherein said encapsulant overlying said first microelectronic element has a first height above said first surface of said dielectric element and said encapsulant overlying said second microelectronic element has a second height above said first surface of said dielectric element, the first height being greater than the second height.
