  • Conductive epoxy flip-chip on chip
    Patent number: 6271598
    Abstract: A flip chip on chip assembly including a first flip chip; a second flip chip directly connected to the top of the first flip chip; and electrically conductive epoxy means disposed between the second flip chip and the top of the first flip chip to form an electrical connection between the first flip chip and the second flip chip. In another preferred embodiment, the present invention provides a flip chip assembly including a plurality of semiconductor chips where the plurality of chips are vertically interconnected on top of one another to form an electrically interconnected stack of chips; a flip chip directly connected to the top chip of the stack of chips; and electrically conductive epoxy means disposed between said flip chip and said top chip to form an electrical connection between the flip chip and the top chip.
    Type: Grant
    Filed: August 22, 1997
    Date of Patent: August 7, 2001
    Assignee: Cubic Memory, Inc.
    Inventors: Alfons Vindasius, Marc E. Robinson, William R. Scharrenberg
