An enclosure is disposed on the substrate, and comprises a main body, and a sidewall projecting axially from outer edges of the main body towards the substrate and contacting the substrate such that an internal volume is defined between the enclosure and the substrate. An insulating layer is insert molded on an inner surface of the enclosure, or over molded on an outer surface of the enclosure such that the insulating layer is not disposed on a portion of the sidewall proximate to the substrate.

Abstract: A sensor device includes a substrate having a front surface and an opposing back surface. The back surface defines an indented region having an indented surface. The substrate defines a bottom port extending between the front surface and the indented surface. The sensor further includes a microelectromechanical systems (MEMS) transducer mounted on the front surface of the substrate over the bottom port. The sensor also includes a filtering material disposed on the indented surface and covering the bottom port. The filtering material provides resistance to ingression of solid particles or liquids into the sensor device. The filtering material is configured to provide high acoustic permittivity and have low impact on a signal-to-noise ratio of the sensor device.
