Zusammenfassung:	The application describes MEMS transducers and associated methods of fabrication. The MEMS transducer has a flexible membrane with a vent structure comprising a moveable portion which opens in response to a differential pressure across the membrane to provide a flow path through the membrane. At least one edge of the moveable portion comprises one or more protrusions and/or recesses in the plane of the moveable portion.
