Abstract
Integrated circuits having shielded micro-electromechanical system (MEMS) devices and method for fabricating shielded MEMS devices are provided. In an example, an integrated circuit having a shielded MEMS device includes a substrate, a ground plane including conductive material over the substrate, and a dielectric layer over the ground plane. The integrated circuit further includes a MEMS device over the ground plane. Also, the integrated circuit includes a conductive pillar through the dielectric layer and in contact with the ground plane. The integrated circuit includes a metallic thin film over the MEMS device and in contact with the conductive pillar, wherein the metallic thin film, the conductive pillar and the ground plane form an electromagnetic shielding structure surrounding the MEMS device. Further, the integrated circuit includes an acoustic shielding structure over the substrate and adjacent the electromagnetic shielding structure.
