Integrated circuit ground shielding structure
First Claim
1. An apparatus, comprising:
- a first die that contains an electronic component;
second die that contains a ground shielding structure, wherein the ground shielding structure device includes a first segment and a second segment, and wherein the first and second segments are formed in different layers, wherein the first and second segments each have a meandrous shape, and wherein the first and second segments are positionally offset from one another in a top view; and
a layer disposed between the first die and the second die, wherein the layer couples the first die and the second die together.

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.
