Electronic package and method of connecting a first die to a second die to form an electronic package

摘要

Some embodiments relate to an electronic package. The electronic package includes a substrate that includes a plurality of buildup layers. A first die is embedded in one of the buildup layers on one side of the substrate. A second die is bonded to the substrate within a cavity 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.

主权项

1. A method comprising:
attaching a first die to a core, wherein attaching the first die to the core includes attaching the first die within a cavity in the core in order to embed the first die in one of the buildup layers on one side of the substrate; fabricating a substrate onto the core, wherein the substrate includes a plurality of buildup layers, wherein the first die is embedded in one of the buildup layers on one side of the substrate; 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; and removing the core from the first die and the substrate.
