  • Patent number: 7554203
    Abstract: An integrated circuit (“IC”) package having two or more dice stacked on a substrate and electrically coupled using two or more different connection technologies may improve high-speed input/output (“I/O”) bandwidth. In an embodiment, one die is a processor and at least one other die is a dynamic random access memory (“DRAM”). One or more of the dice may be thinned and placed between the substrate and a portion of one or more of the other dice, which may be horizontally offset. One or more of the dice may be embedded in the substrate. The dice may be coupled to each other and to the substrate using a combination of controlled-collapse chip connection (“C4”) and wirebonding connection technologies.

  • Publication number: 20090162005
    Abstract: In general, in one aspect, a method includes forming conductive layers on a wafer. A through cavity is formed in alignment with the conductive layers. The through cavity is to permit an optical signal from an optical waveguide within an optical connector to pass therethrough. Alignment holes are formed on each side of the through cavity to receive alignment pins. The wafer having the conductive layers, the through cavity in alignment with the conductive layers, and the alignment holes on each side of the through cavity forms an optical-electrical (O/E) interface. An O/E converter is mounted to the metal layers in alignment with the through cavity. The alignment pins and the alignment holes are used to passively align the optical waveguide and the O/E converter.
