  • Patent number: 7329895
    Abstract: A sensor comprises two photodiodes sensitive to different wavelengths. The photodiodes or detectors are stacked in a vertical relationship to each other. A bandpass filter is provided to limit the wavelengths of light reaching the detectors. The photodiodes are formed of various combinations of materials such as AlGaN or InGaN, or different compositions of the same material. Charge detectors are coupled to each detector to provide a signal representative of the amount of radiation detected in their corresponding bandwidths. A biological sample is provided proximate the filter. A laser is used to illuminate the biological sample to create biofluorescence corresponding to intrinsic tryptophan of bacteria.

    Abstract: The invention proposes an interposer assembly architecture for noise suppression circuits on the package of a CPU or high power, high frequency VLSI device. In this architecture, charge is stored on dedicated capacitors at a voltage substantially higher than the operating voltage of the VLSI device. These capacitors are mounted upon active circuits that are packaged to match the size and form factor of the capacitors and this assembly is then attached to the package substrate. Charge is conveyed from the capacitor terminals on the backside of the packaged active circuits chip. Depending upon the capacitor construction, these terminals may either be double-sided contact terminals along the edge of the active device's package, or may be feed-through contacts.

  • Patent number: 7154171
    Abstract: A semiconductor stacking structure has a semiconductor device. A flexible substrate is coupled to a bottom surface of the semiconductor device. The flexible substrate is folded over on at least two sides to form flap portions. The flap portions are coupled to an upper surface of the first semiconductor device and covers only a portion of the upper surface of the semiconductor device.

  • Patent number: 7145247
    Abstract: The present invention is aimed at bonding a lower chip and an upper chip through bumps in a highly reliable manner, while ensuring a sufficient area for an external connection terminal region, by offsetting the upper chip to the lower chip. The substrate 2 has bumps 1 arranged on one surface thereof, and has a first chip 3 mounted on the other surface thereof. A second chip 4 is bonded to the first chip 3 through bumps 5, 6 while offsetting the second chip 4 to the first chip 3 in parallel. In the bonded state of the first chip 3 and the second chip 4, a part of the first chip 3 and a part of the second chip 4 are overlapped without aligning the centers of the both. The center of gravity of the second chip 4 falls inside a region surrounded by the outermost bumps between the first chip 3 and the second chip 4.

  • Patent number: 7119425
    Abstract: The chip package includes a first and second semiconductor chip. The first semiconductor chip has a first connection structure that electrically connects to a bond pad on a first surface of the first semiconductor chip. The second semiconductor chip has a second connection structure. The second connection structure is electrically connected to a bond pad on a first surface of the second semiconductor chip and extends through the second semiconductor chip to a second surface of the second semiconductor chip. A portion of the second connection structure extending to the second surface of the second semiconductor chip is electrically connected to the first connection structure and formed of a harder material than the first connection structure.

  • Patent number: 7081373
    Abstract: A chip stack comprising a flex circuit including a flex substrate having a first conductive pattern disposed thereon and a plurality of leads extending therefrom. Also included in the chip stack are at least two integrated circuit chip packages. The integrated circuit chip packages may be electrically connected to the first conductive pattern of the flex circuit such that the integrated circuit chip packages are positioned upon respective ones of opposed top and bottom surfaces of the flex substrate. Alternatively, one of the integrated circuit chip packages may be positioned upon the top surface of the flex substrate and electrically connected to the first conductive pattern, with the remaining integrated circuit chip package being attached in a non-conductive manner to the bottom surface of the flex substrate such that the conductive contacts of such integrated circuit chip package and the leads collectively define a composite footprint for the chip stack.

  • Patent number: 7067927
    Abstract: A variety of techniques and structures are described that integrate an insulated pedestal into the back surface of integrated circuit dice. The die has an insulated integral pedestal formed therein that acts as a spacer. The pedestal has a footprint that is smaller than the total footprint of the die so that a portion of the active region of the die overhangs the pedestal. The geometry of the pedestal may be widely varied and in some embodiments, multiple pedestals may be provided on the stacked die. In another aspect, the pedestals are formed at the wafer level such that the pedestals are defined in the back surface of the wafer. Often, the thickness of the pedestals will be thicker than the portions of the wafer outside the pedestal areas. The described dice are particularly well suited for use in stacked die packages.
