  • Patent number: 8222086
    Abstract: A plurality of FPGA dice is disposed upon a semiconductor substrate. In order both to connect thousands of signal interconnect lines between the plurality of FPGA dice and to supply the immense power required, it is desired that the substrate construction include two different portions, each manufactured using incompatible processes. The first portion is a signal interconnect structure containing a thin conductor layers portion characterized as having a plurality of thin, fine-pitch conductors. The second portion is a power connection structure that includes thick conductors and vertical through-holes. The through-holes contain conductive material and supply power to the FPGA dice from power bus bars located at the other side of the semiconductor substrate. The portions are joined at the wafer level by polishing the wafer surfaces within a few atoms of flatness and subsequent cleaning. The portions are then fusion bonded together or combined using an adhesive material.

  • Patent number: 8129834
    Abstract: A plurality of FPGA dice is disposed upon a semiconductor substrate. In order to supply the immense power required by the plurality of FPGA dice, power is routed through the semiconductor substrate vertically from thick metal layers and large integral metal structures located on the other side of the semiconductor substrate. Because the semiconductor substrate has a different coefficient of thermal linear expansion than metal layers in contact with the substrate, delamination may occur when the structure is subject to changes in temperature. To prevent delamination of metal layers connected to the semiconductor substrate and in electrical contact with the integral metal structures, the integral metal structures are manufactured with an array of post portions. During changes in temperature, the post portions of the integral metal structures bend and slide relative to metal layers connected to the semiconductor substrate and prevent linear stresses that may otherwise cause delamination.
