  • Patent number: 8723308
    Abstract: Packaged integrated devices and methods of forming the same are provided. In one embodiment, a packaged integrated device includes a package substrate, a package lid, and an integrated circuit or microelectromechanical systems (MEMS) device. The package lid is mounted to a first surface of the package substrate using an epoxy, and the package lid and the package substrate define a package interior. The package lid includes an interior coating suited to good adhesion with the epoxy, and an exterior coating suited to RF shielding, where the materials of the interior and exterior coatings are different. In one example, the interior lid coating is nickel whereas the exterior lid coating is tin.

  • Publication number: 20140091406
    Abstract: A MEMS microphone system suited for harsh environments. The system uses an integrated circuit package. A first, solid metal lid covers one face of a ceramic package base that includes a cavity, forming an acoustic chamber. The base includes an aperture through the opposing face of the base for receiving audio signals into the chamber. A MEMS microphone is attached within the chamber about the aperture. A filter covers the aperture opening in the opposing face of the base to prevent contaminants from entering the acoustic chamber. A second metal lid encloses the opposing face of the base and may attach the filter to this face of the base. The lids are electrically connected with vias forming a radio frequency interference shield. The ceramic base material is thermally matched to the silicon microphone material to allow operation over an extended temperature range.
