Abstract

The MEMS package has a mounting substrate on which one or more transducer chips are mounted wherein the mounting substrate has an opening. A top cover is attached to and separated from the mounting substrate by a spacer forming a housing enclosed by the top cover, the spacer, and the mounting substrate and accessed by the opening. Electrical connections are made between the one or more transducer chips and the mounting substrate and/or between the one or more transducer chips and the top cover. A bottom cover can be mounted on a bottom surface of the mounting substrate wherein a hollow chamber is formed between the mounting substrate and the bottom cover, wherein a second opening in the bottom cover is not aligned with the first opening. Pads on outside surfaces of the top and bottom covers can be used for further attachment to printed circuit boards. The top and bottom covers can be a flexible printed circuit board folded under the mounting substrate.
