  • Patent number: 10636780
    Abstract: Laminated interposers and packages, with embedded trace interconnects are provided. An example process for making an interposer or package achieves vertical conductive vias in the package by depositing conductive traces on multiple wafers or panes, then laminating these substrates into a stack, thereby embedding the conductive traces. The laminated stack is sliced to dimensions of an interposer or electronic package. A side of the sliced stack is then used as the top of the interposer or package, rendering some of the horizontally laid traces into vertical conductive vias. The interposer or package can be finished or developed by adding redistribution layers on the top and bottom surfaces, and active and passive components. Electronic components can also be embedded in the laminated stack. Some of the stack layers can be active dies, such as memory controllers, memory storage arrays, and processors, to form a memory subsystem or self-contained computing device.

  • Patent number: 10623710
    Abstract: HD color video using monochromatic CMOS image sensors integrated in a 3D package is provided. An example 3DIC package for color video includes a beam splitter to partition received light of an image stream into multiple light outputs. Multiple monochromatic CMOS image sensors are each coupled to one of the multiple light outputs to sense a monochromatic image stream at a respective component wavelength of the received light. Each monochromatic CMOS image sensor is specially constructed, doped, controlled, and tuned to its respective wavelength of light. A parallel processing integrator or interposer chip heterogeneously combines the respective monochromatic image streams into a full-spectrum color video stream, including parallel processing of an infrared or ultraviolet stream. The parallel processing of the monochromatic image streams provides reconstruction to HD or 4K HD color video at low light levels.

  • Patent number: 10600760
    Abstract: Capacitive coupling of integrated circuit die components and other conductive areas is provided. Each component to be coupled has a surface that includes at least one conductive area, such as a metal pad or plate. An ultrathin layer of dielectric is formed on at least one surface to be coupled. When the two components, e.g., one from each die, are permanently contacted together, the ultrathin layer of dielectric remains between the two surfaces, forming a capacitor or capacitive interface between the conductive areas of each respective component. The ultrathin layer of dielectric may be composed of multiple layers of various dielectrics, but in one implementation, the overall thickness is less than approximately 50 nanometers. The capacitance per unit area of the capacitive interface formed depends on the particular dielectric constants ? of the dielectric materials employed in the ultrathin layer and their respective thicknesses.

  • Patent number: 10600747
    Abstract: Vertical capacitors for microelectronics are provided. An example thin capacitor layer can provide one or numerous capacitors to a semiconductor chip or integrated circuit. In an implementation, a thin capacitor layer of 50-100 ?m thickness may have 5000 vertically disposed capacitor plates per linear centimeter, while occupying only a thin slice of the package. Electrodes for each capacitor plate are accessible at multiple surfaces. Electrode density for very fine pitch interconnects can be in the range of 2-200 ?m separation between electrodes. A redistribution layer (RDL) may be fabricated on one or both sides of the thin capacitor layer to provide fan-out ball grid arrays that occupy insignificant space. RDLs or through-vias can connect together sets of the interior vertical capacitor plates within a given thin capacitor layer to form various capacitors from the plates to meet the needs of particular chips, dies, integrated circuits, and packages.

  • Publication number: 20200091110
    Abstract: Systems and methods for providing 3D wafer assembly with known-good-dies are provided. An example method compiles an index of dies on a semiconductor wafer and removes the defective dies to provide a wafer with dies that are all operational. Defective dies on multiple wafers may be removed in parallel, and resulting wafers with all good dies stacked in 3D wafer assembly. In an implementation, the spaces left by removed defective dies may be filled at least in part with operational dies or with a fill material. Defective dies may be replaced either before or after wafer-to-wafer assembly to eliminate production of defective stacked devices, or the spaces may be left empty. A bottom device wafer may also have its defective dies removed or replaced, resulting in wafer-to-wafer assembly that provides 3D stacks with no defective dies.

  • Patent number: 10586759
    Abstract: An interposer (110) has contact pads at the top and/or bottom surfaces for connection to circuit modules (e.g. ICs 112). The interposer includes a substrate made of multiple layers (110.i). Each layer can be a substrate (110S), possibly a ceramic substrate, with circuitry. The substrates extend vertically. Multiple interposers are fabricated in a single structure (310) made of vertical layers (310.i) corresponding to the interposers' layers. The structure is diced along horizontal planes (314) to provide the interposers. An interposer's vertical conductive lines (similar to through-substrate vias) can be formed on the substrates' surfaces before dicing and before all the substrates are attached to each other. Thus, there is no need to make through-substrate holes for the vertical conductive lines. Non-vertical features can also be formed on the substrates' surfaces before the substrates are attached to each other. Other embodiments are also provided.
