Abstract:
1. A microelectronic substrate, comprising: a first microelectronic substrate core having a first surface and an opposing second surface, said first microelectronic substrate core having at least one opening defined therein extending from said first microelectronic substrate core first surface to said first microelectronic substrate core second surface; at least one first microelectronic device disposed within said at least one opening, said at least one first microelectronic device having an active surface and a back surface, wherein said first microelectronic device active surface is adjacent said first microelectronic substrate core first surface; a first encapsulation material adhering said first microelectronic substrate core to said at least one first microelectronic device forming a first surface adjacent said microelectronic die active surface and said core first surface and a second surface adjacent said microelectronic die back surface and said core second surface; a second microelectronic substrate core having a first surface and an opposing second surface, said second microelectronic substrate core having at least one opening defined therein extending from said second microelectronic substrate core first surface to said second microelectronic substrate core second surface; at least one second microelectronic device disposed within said at least one opening, said at least one second microelectronic device having an active surface and a back surface, wherein said second microelectronic device active surface is adjacent said second microelectronic substrate core first surface; a second encapsulation material adhering said second microelectronic substrate core to said at least one second microelectronic device forming a first surface adjacent said microelectronic die active surface and said core first surface and a second surface adjacent said microelectronic die back surface and said core second surface; and said first microelectronic device active surface oriented to face said second microelectronic device active surface.
