    摘要: Semiconductor devices having redundant through-die vias (TDVs) and methods of fabricating the same are described. A substrate is provided having conductive interconnect formed on an active side thereof. Through die vias (TDVs) are formed in the substrate between a backside and the active side thereof. The TDVs include signal TDVs, redundant TDVs (i.e., redundant signal TDVs), and power supply TDVs. The signal TDVs are spaced apart from the redundant TDVs to form a pattern of TDV pairs. The power supply TDVs are interspersed among the TDV pairs. The conductive interconnect includes first signal conductors electrically coupling each of the signal TDVs to a respective one of the redundant TDVs defining a respective one of the TDV pairs.

    摘要: An integrated circuit device is described that includes a stacked die and a base die having probe pads that directly couple to test logic of the base die so as to implement a scan chain for testing of the integrated circuit device. The base die further includes contacts disposed on a back side of the base die and through-die vias coupled to the contacts and coupled to programmable logic of the base die. In addition, the base die includes a first probe pad configured to couple test input, a second probe pad configured to couple test output and a third probe pad configured to couple control signals. Test logic of the base die is configured to couple to additional test logic of the stacked die so as to implement a scan chain for testing of the integrated circuit device. In accordance with aspects of the present invention, the first probe pad, the second probe pad and the third probe pad are coupled directly to the test logic such that configuration of the programmable logic is not required for coupling the test input, the test output and the control signal between the base die and the stacked die so as to implement the scan chain.

    摘要: A method for forming a stacked-die structure is disclosed in which a buried oxide layer is formed in a semiconductor wafer. Device layers and metal layers are formed on the face side of the semiconductor wafer, defining dice, with each die including an interconnect region. Openings are etched in the interconnect regions that extend through the semiconductor wafer so as to expose portions of the buried oxide layer. Conductive material is deposited within the openings so as to form through-die vias. The semiconductor wafer is then attached to a wafer support structure and material is removed from the backside of the semiconductor wafer so as to form an oxide layer having a thickness that is less than the initial thickness of the buried oxide layer. Openings are then etched within the backside of the semiconductor wafer so as to expose the through-die vias, micro-bumps are deposited over the through-die vias, and stacked dice are attached to the micro-bumps so as to electrically couple the stacked dice to the through-die vias. Thereby, a stacked die structure is formed that includes an oxide layer on the backside of the base die. Since the method does not include any high temperature process steps after the semiconductor wafer has been attached to the wafer support structure, thermally-released double-sided tape or adhesive having a low thermal budget can be used to attach the semiconductor wafer to the wafer support structure.

    摘要: Leakage current reduction from a logic block is implemented via power gating transistors that exhibit increased gate oxide thickness as compared to the thin-oxide devices of the power gated logic block. Increased gate oxide further allows increased gate to source voltage differences to exist on the power gating devices, which enhances performance and reduces gate leakage even further. Placement of the power gating transistors in proximity to other increased gate oxide devices minimizes area penalties caused by physical design constraints of the semiconductor die.
