Abstract
A package for a top port microphone with an enlarged back volume. The package includes on a substrate a lid enclosing thereunder a total volume and accommodating a MEMS chip and an ASIC. A stopper seals the ASIC against the lid thereby separating and dividing the total volume under the lid in a volume extension and a remaining volume. The volume extension can be used to arbitrarily enlarge the back volume or the front volume dependent on a placement of a sound port to the volume extension or the remaining volume. A sound path connects the volume extension and a partial volume enclosed between MEMS chip and substrate.
