Abstract
The present disclosure describes a process for making a three-dimensional (3D) package, which starts with providing a mold precursor module that includes a first device die and a floor connectivity die (FCD) encapsulated by a mold compound. The FCD includes a sacrificial die body and multiple floor interconnections underneath the sacrificial die body. Next, the mold compound is thinned down until the sacrificial die body of the FCD is completely consumed, such that each floor interconnection is exposed through the mold compound. The thinning down step does not affect a device layer in the first device die. A second device die, which includes a die body and multiple electrical die interconnections, is then mounted over the exposed floor interconnections. Herein, each electrical die interconnection is vertically aligned with and electrically connected to a corresponding floor interconnection from the FCD.
