Abstract
The present disclosure provides an Integrated Circuit (IC) device. The IC device includes a first die that contains an electronic component. The IC device includes second die that contains a ground shielding structure. The IC device includes a layer disposed between the first die and the second die. The layer couples the first die and the second die together. The present disclosure also involves a microelectronic device. The microelectronic device includes a first die that contains a plurality of first interconnect layers. An inductor coil structure is disposed in a subset of the first interconnect layers. The microelectronic device includes a second die that contains a plurality of second interconnect layers. A patterned ground shielding (PGS) structure is disposed in a subset of the second interconnect layers. The microelectronic device includes an underfill layer disposed between the first and second dies. The underfill layer contains one or more microbumps.
