Abstract: A microelectromechanical system (MEMS) hermetically sealed package device that is less labor intensive to construct and thus less expensive to manufacture. An example package device includes a package having a bottom section and a lid. A MEMS die includes upper and lower plates made in accordance with upper sense plate design. The MEMS die is mounted to the bottom section. The upper and lower plates form a cavity that receives a MEMS device. The upper and lower plates are bonded by one or more bond pads and a seal ring that surrounds the cavity. The seal ring includes grooves that allow exposure of the cavity to the space within the package. A getter material applied to a top surface of the MEMS die on the upper plate. The getter material is activated during or after the lid is mounted to the bottom section.

Abstract: A Leadless Chip Carrier (LCC) device and method of attaching a Microelectromechanical (MEMS) device into an LCC package. An alignment plate is die bonded into the bottom of an LCC. The alignment plate includes fiducials fabricated into top and bottom metal layers, thus producing a tolerance that will be an order of magnitude better than the tolerance of fiducials included in the LCC. A bump pattern and MEMS die are attached based on the alignment plate and fiducials giving a much improved die to bump alignment.
