A method of testing a multi-die integrated circuit (IC) can include testing an inter-die connection of the multi-die IC. The inter-die connection can include a micro-bump coupling a first die to a second die. The method can include detecting whether a fault occurs during testing of the inter-die connection. Responsive to detecting the fault, the multi-die integrated circuit can be designated as including a faulty inter-die connection. Also described is an integrated circuit that includes a first die, a second die on which the first die may be disposed, a plurality of inter-die connections coupling the first die to the second die, and a plurality of probe pads, where each probe pad is coupled to at least one of the inter-die connections.
摘要:
An integrated circuit (IC) combines a first IC chip (die) having a first on-chip interconnect structure and a second IC chip having a second on-chip interconnect structure on a reconstructed wafer base. The second IC chip is edge-bonded to the first IC chip with oxide-to-oxide edge bonding. A chip-to-chip interconnect structure electrically couples the first IC chip and the second IC chip.

A package-on-package (POP) structure is disclosed. The POP structure includes a first die, a second die, and a photo-imaged dielectric (PID) layer. The PID layer is disposed between the first die and the second die. The POP structure also includes a first conductive path from the first die through the PID layer to the second die. The first conductive path extends directly through a first area of the PID layer directly between the first die and the second die. The POP structure further includes a second conductive path from the first die through the PID layer to the second die. A particular portion of the second conductive path is perpendicular to the first conductive path and extends through a second area of the PID layer not directly between the first die and the second die.

Some embodiments relate to an electronic package. The electronic package includes a substraten (11) that includes a plurality of buildup layers (12A,12B,12C). A first die (13) is embedded in one of the buildup layers on one side of the substrate. A second die(16) is bonded to the substrate within a cavity (17) on an opposing side of the substrate. The first die and the second die may be electrically connected to conductors within the plurality of buildup layers. Other embodiments relate to method of connecting a first die to a second die to form an electronic package. The method includes attaching a first die to a core and fabricating a substrate onto the core. The method further includes creating a cavity in another of the buildup layers on an opposing side of the substrate and attaching a second die to the substrate within the cavity.

A multi-chip integrated circuit (IC) package is provided which is configured to protect against failure due to warpage. The IC package may comprise a substrate (514), a level-one IC die (502) and a plurality of level-two IC dies (512a, 512b). The level-one IC die having a surface that is electrically coupled (520) to the substrate. The plurality of level-two IC dies is stacked above the level-one IC die. The plurality of level-two IC dies may each have an active surface that is electrically coupled (516,518) to the substrate. The plurality of level-two IC dies may be arranged side by side such that the active surfaces of the plurality of level-two IC dies are positioned substantially in a same plane. Relative to a single die configuration, the level-two IC dies are separated thereby inhibiting cracking, peeling and/or other potential failures due to warpage of the IC package.
