A recently granted patent (Publication Number: US11912564B2) discloses a microelectromechanical systems (MEMS) sensor package that includes a substrate with multiple layers, a transducer, and an inductor. The inductor is configured as a single layer trace on an inductor layer within the substrate, positioned between specific layers within the substrate. The transducer consists of a diaphragm and a back plate, with the substrate housing a sound port acoustically connected to the diaphragm. Notably, the design ensures no other inductors are present between layers in a direction perpendicular to the plane of the inductor layer, with the sound port passing between traces of the inductor.

Furthermore, the patent details additional features of the MEMS sensor package, such as the inclusion of a capacitor electrically coupled to the inductor, a capacitor physically located within the substrate, and an application-specific integrated circuit connected to the substrate. The configuration of the inductor, capacitor, and integrated circuit within the sensor package is meticulously described, emphasizing the specific electrical connections and contacts between these components. The patent also highlights the presence of solder pads and the strategic placement of the inductor adjacent to these pads, showcasing a comprehensive and innovative design approach in the development of sensor packages.
