20100027171 | Method and Apparatus for Forming I/O Clusters in Integrated Circuits - A first I/O pad has a first type transistor disposed at a first end of the first I/O pad. A second I/O pad has another first type transistor disposed at a first end of the second I/O pad. The first end of the first I/O pad abuts the first end of the second I/O pad, so the first type transistor is adjacent to the other first type transistor. | 02-04-2010 |
20100060312 | Testing Circuit Split Between Tiers of Through Silicon Stacking Chips - A method of testing a die having a non-testable circuit, where the non-testable circuit is logically incomplete and forms part of a logically complete multiple tier circuit. The method includes reconfiguring a tier-to-tier input point or tier-to-tier output point associated with a primary path of the non-testable circuit to create a logically complete secondary path for the tier-to-tier point such that the non-testable circuit can be tested. Testable dies and methods of preparing such dies are also provided. | 03-11-2010 |
20100075460 | Low Cost Die-To-Wafer Alignment/Bond For 3d IC Stacking - The cost associated with alignment in a stacked IC device can be reduced by aligning multiple die instead of a single die during the alignment step. In one embodiment, the alignment structures are placed in the scribe line instead of within the die itself. Aligning four die instead of one eliminates the need for as many alignment indicators and thus more silicon on the wafer can be used for active areas. In addition, this method allows for yield improvement through binning of dies having the same yield configuration. | 03-25-2010 |
20100091475 | Electrostatic Discharge (ESD) Shielding For Stacked ICs - An unassembled stacked IC device includes an unassembled tier. The unassembled stacked IC device also includes a first unpatterned layer on the unassembled tier. The first unpatterned layer protects the unassembled tier from ESD events. | 04-15-2010 |
20100140750 | Parallel Plane Memory and Processor Coupling in a 3-D Micro-Architectural System - An IC device is constructed in a manner that allows for the memory and processor elements to be positioned one above the other on parallel planes of a 3-D structure. Interconnections between the memory(s) and the processor(s) are accomplished by using through substrate stacking (TSS) techniques. This arrangement provides the processor with direct access to the memory by reducing the distance between the memory and the processor. | 06-10-2010 |
20100155931 | Embedded Through Silicon Stack 3-D Die In A Package Substrate - An integrated circuit package has a die or die stack with through silicon vias embedded in a package substrate. A method of producing an integrated circuit package embeds at least one die with a through silicon via in a package substrate.

20100188114 | Circuit for Detecting Tier-to-Tier Couplings in Stacked Integrated Circuit Devices - A first semiconductor tier has a first tier-to-tier connector for detecting a tier-to-tier coupling in a stacked integrated circuit (IC) device. A second semiconductor tier has a second tier-to-tier connector configured to electrically couple to the first tier-to-tier connector. A tier-to-tier detection circuit electrically couples to the second tier-to-tier connector. The tier-to-tier detection circuit generates an output signal indicative of an electrical coupling between the first semiconductor tier and the second semiconductor tier. | 07-29-2010 |
