An electronic device may include a first die that may include a first set of die contacts. The electronic device may include a second die that may include a second set of die contacts. The electronic device may include a bridge interconnect that may include a first set of bridge contacts and may include a second set of bridge contacts. The first set of bridge contacts may be directly coupled to the first set of die contacts (e.g., with an interconnecting material, such as solder). The second set of bridge contacts may be directly coupled to the second set of die contacts (e.g., with solder). The bridge interconnect may help facilitate electrical communication between the first die and the second die.

Multi-chip packaging

Techniques and mechanisms to mitigate contamination of redistribution layer structures disposed on a back side of a semiconductor substrate. In an embodiment, a microelectronics device includes a substrate and integrated circuitry variously formed in or on a front side of the substrate, where vias extend from the integrated circuitry to a back side of the substrate. A redistribution layer disposed on the back side includes a ring structure and a plurality of raised structures each extending from a recess portion that is surrounded by the ring structure. The ring structure and the plurality of raised structures provide contact surfaces for improved adhesion of dicing tape to the back side. In another embodiment, the plurality of raised structures includes dummification comprising dummy structures that are each electrically decoupled from any via extending through the substrate.

Structures to mitigate contamination on a back side of a semiconductor substrate

A method including forming a contact pad array on an integrated circuit substrate, the contact pad array including a first plurality of contact pads and a second plurality of contact pads, wherein an accessible area of each of the first plurality of contact pads is different than an accessible area of each of the second plurality of contact pads; and depositing solder on the accessible area of the contact pads. An apparatus including an integrated circuit substrate including a body having a nonplanar shape and a surface including a first plurality of contact pads and a second plurality of contact pads, wherein an accessible area of each of the first plurality of contact pads is different than an accessible area of each of the second plurality of contact pads.
