    Abstract: The present invention relates to a method of manufacturing an MEMS device that comprises the steps of forming a first membrane layer over a sacrificial base layer, forming a second membrane layer over the first membrane layer, wherein the second membrane layer comprises lateral recesses exposing lateral portions of the first membrane layer and forming stoppers to restrict movement of the first membrane layer. Moreover, it is provided MEMS device comprising a movable membrane comprising a first membrane layer and a second membrane layer formed over the first membrane layer, wherein the second membrane layer comprises lateral recesses exposing lateral portions of the first membrane layer.
