<p>The electronic device (100) comprises an electrical element (30), for instance a MEMS capacitor or a BAW filterin a cavity (37) that is protected from the environment by a cover (38). The cover (38) is a patterned layer which is mechanically embedded in isolating material (7) present beside the cavity (37) and may further include contact pads (41). The device (100) may be suitably manufactured from an accurately folded foil including a patterned layerand a sacrifice layer. After applying the foil to the cavity (37) the isolating material (7) is provided and the sacrifice layer is removed. The patterned layer, or part thereof, stays behind and forms the cover (38).</p> |
