Abstract:
A 3-dimensional hybrid package including an integrated circuit chip stack formed on a laminate, the integrated chip stack further including a first chip and a second chip. The first chip is connected to the laminate through first solder bumps, each associated with a first through-silicon via (TSV), and first metal leads embedded in a first polymer tape that extends from first peripheral metal pads formed on a back side of the first chip to the laminate. The second chip is connected to the first peripheral metal pads on the back side of the first chip through second solder bumps formed on a front side of the second chip. The second chip is connected to the laminate by second metal leads, embedded in a second polymer tape that extend from second peripheral metal pads formed on a back side of the second chip to the laminate.
Abstract:
Aspects of the present disclosure provide an integrated circuit (IC) wafer having a plurality of circuit dies each bounded by a set of scribe lines. The IC structure includes: a plurality of reference features each respectively positioned in a first layer of one of the plurality of circuit dies. The reference feature of each circuit die is equidistant from a respective set of scribe lines for the circuit die, and a plurality of identification features each positioned in a second layer of one of the plurality of circuit dies. The reference feature of each circuit die has a distinct offset vector indicative of a positional difference between the identification feature for the circuit die and the reference feature for the circuit die, relative to the identification feature of each other circuit die.

Abstract:
In an approach to fabricating a silicon on insulator wafer, one or more semiconductor device elements are implanted and one or more shallow trench isolations are formed on a top surface of a first semiconductor wafer. A first dielectric material layer is deposited over the top surface of the first semiconductor wafer, filling the shallow trench isolations. A dielectric material layer on a bottom surface of a second semiconductor wafer is bonded to a dielectric material layer on the top of the first semiconductor wafer and one or more semiconductor devices are formed on a top surface of the second semiconductor wafer. Then, one or more through silicon vias are created connecting the one or more semiconductor devices on the top surface of the second semiconductor wafer and the one or more semiconductor device elements on the top surface of the first semiconductor wafer.
