Abstract

Packages and methods for 3D integration are disclosed. In various embodiments, a first integrated device die having a hole is attached to a package substrate. A second integrated device die can be stacked on top of the first integrated device die. At least a portion of the second integrated device die can extend into the hole of the first integrated device die. By stacking the two dies such that the portion of the second integrated device die extends into the hole, the overall package height can advantageously be reduced.
