Abstract
An integrated circuit (IC) structure includes a first IC package (ICP), including a first resist surface provided with a first plurality of conductive contacts (CCs), a first recess including a second resist surface disposed at a bottom of the recess and having a second plurality of CCs, and a second recess, including a third resist surface disposed at a bottom of the recess and provided with a fourth plurality of CCs. The IC structure further includes an IC component with a first surface and a second surface, the second surface having a third plurality of CCs coupled to the second plurality of CCs of the first ICP. The IC structure further includes a second ICP having a first surface and a second surface, with one or more CCs located at the second surface and coupled to at least one of the first plurality of CCs of the first ICP.
