    Abstract: A microelectromechanical is provided that includes a support layer, a device layer and a cap layer, a first cavity and a second cavity. The first cavity and the second cavity are delimited by the support layer, the device layer and the cap layer. Moreover, the cap layer includes a through-hole that extends from the top surface of the cap layer to the first cavity. The microelectromechanical component includes a plug inside the through-hole and that seals the first cavity.
