Abstract:
A semiconductor device package includes a logic die (102) coupled to a memory die (108) in a face-to-face configuration with small interconnect pitch (at most about 50 pm) and small distances between the die (at most about 50 pm). The logic die may be connected to a redistribution layer (112) with terminals that are fanned out, or spaced out, to provide space for the face-to-face connections to the memory die. The memory die may be connected to the logic die before or after the logic die is connected to the redistribution layer. The logic die and the memory die may be at least partially encapsulated in an encapsulant (110). Routing (114) in the redistribution layer may connect the logic die and/or the memory die to ball grid array terminals coupled to the bottom of the redistribution layer and/or discrete devices (118) coupled to the redistribution layer.
Abstract:
Packages and methods of formation are described. In an embodiment, a package includes a redistribution layer (RDL) (130) formed directly on a top die (110), and a bottom die (150) mounted on a back surface of the RDL.
Abstract:
Packages and methods of formation are described. In an embodiment, a system in package (SiP) includes first and second redistribution layers (RDLs), and a plurality of die attached to the front and back side of the first RDL. The first and second RDLs are coupled together with a plurality of conductive pillars extending from the back side of the first RDL to a front side of the second RDL.
