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.

3D stacked piezoresistive pressure sensor

In a microelectromechanical system (MEMS) pressure sensor, thin and fragile bond wires that are used in the prior art to connect a MEMS pressure sensing element to an application specific integrated circuit (ASIC) for the input and output signals between these two chips are replaced by stacking the ASIC on the MEMS pressure sensing element and connecting each other using conductive vias formed in the ASIC. Gel used to protect the bond wires, ASIC and MEMS pressure sensing element can be eliminated if bond wires are no longer used. Stacking the ASIC on the MEMS pressure sensing element and connecting them using conductive vias enables a reduction in the size and cost of a housing in which the devices are placed and protected.
